Herein, a Zn(II)-based macrocyclic metal–organic framework (FCS-6) was constructed and employed as an ultrasensitive chemical sensor for antibiotics detection. FCS-6 demonstrates excellent structural stability and exhibits distinct fluorescence responses in simulated antibiotic-contaminated wastewater. Specifically, the fluorescence of FCS-6 could be selectively enhanced by norfloxacin (NFX) and ciprofloxacin (CFX), while being quenched by nitrofurantoin (NFT). Notably, FCS-6 displayed excellent detection ability, with limits of detection (LOD) of 1.9, 4.7, and 10.1 ppm for NFX, CFX, and NFT, respectively. Mechanism studies demonstrated that the fluorescence variation of FCS-6 toward NFX, CFX, and NFT could be attributed to specific molecular recognition and electron transfer processes between FCS-6 and the antibiotics. This study provides a reference for the rational design and synthesis of MOF-based multiresponsive fluorescent sensors and offers more possibilities for the ultrasensitive detection of antibiotics in water.","PeriodicalId":34,"journal":{"name":"Crystal Growth & Design","volume":"25 18","pages":"7810–7816"},"PeriodicalIF":3.4,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145094527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A combined analysis protocol using polarized optical microscopy (POM), differential scanning calorimetry (DSC), small-angle X-ray scattering (SAXS), and wide-angle X-ray scattering (WAXS) revealed a favorably wide range of nematic phases near room temperature and a slow tendency to crystallize. This should be advantageous in applications requiring good surface-alignment of the reactive mesogen in the nematic phase. This behavior could be attributed to the effects of polymerization under prolonged high temperatures for acrylates and the high entropy of long, branched, flexible alkyl chains in dienes. The polymerization process induces a kinetic competition between LC ordering and network formation. This work establishes protocols for real-time phase monitoring during polymerization, resolving longstanding ambiguities in LC phase identification under thermal polymerization. Furthermore, photocuring tests of the acrylate and diene monomers demonstrated high photopolymerization efficiency and good thermal stability, particularly for the acrylate monomers.","PeriodicalId":34,"journal":{"name":"Crystal Growth & Design","volume":"25 18","pages":"7669–7683"},"PeriodicalIF":3.4,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145094674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we examine the influence of charged nanobubbles, generated through vortexing ionic solutions (bi-/carbonate buffer at pH 10) with rotating nonmagnetic and magnetic impeller, on the formation of amorphous CaCO3 (ACC). Multi-angle light scattering and zeta potential nanoparticle tracking analysis show that alternating magnetic fields influence the size and charge of nanobubbles created by shear forces in vortexing. The altered nanobubble populations delay the formation of solid ACC by inhibiting the aggregation and coalescence of dense liquid calcium carbonate. We propose colloidal stabilization of the dense liquid intermediate by the nanobubbles along the pathway to solidification. Our findings suggest that magnetically manipulating nanobubble populations is a novel approach to controlling mineral scaling and designing advanced materials. This work highlights the potential role of nanobubbles in affecting mineral formation processes and provides new insights into mineralization control through physical treatment methods.This study demonstrates that magnetic vortexing creates a stable, negatively charged nanobubble population which delays the formation of solid ACC by inhibiting the aggregation and coalescence of dense liquid calcium carbonate.

Optimal enhancements were achieved with specific ion concentrations: the CMSO:0.01Cr phosphor codoped with 0.8 at. % Na2CO3 exhibited a 1.8-fold increase in emission intensity, while the CMSO:0.04Cr phosphor codoped with 1.5 at. % Li2CO3 demonstrated an 8-fold enhancement. Charge compensation also improved the internal quantum yield (IQY) and photoelectric conversion efficiency without compromising the thermal stability.

However, tuning their solid-state photoluminescent emissions remains a significant challenge. In this study, we report the synthesis and characterization of five cocrystals (two cocrystal polymorphs) derived from a pristine imidazolinone derivative (A) and the various coformer molecules, namely 1,2,4,5-tetrafluoro-3,6-diiodobenzene, 1,2,4,5-tetrafluoro-3,6-dibromobenzene, perfluoronaphthalene, and 3,4,5-trifluorobenzoic acid. The structural and optical properties of these cocrystals were examined by using single-crystal X-ray diffraction, absorption spectroscopy, photoluminescence spectroscopy, and photoluminescence decay spectroscopy. Cocrystals I, II, and III are isomorphous pairs and exhibit three-dimensional isostructurality, where the coformer molecules bridge adjacent helices of compound A, leading to aggregation-induced emission. In contrast, the cocrystal polymorphs IVA and IVB developed using coformer 3,4,5-trifluorobenzoic acid form two-dimensional sheet-like structures mediated by π-stacking interactions between the coformers and molecule A, with interplanar distances ranging from 3.2 to 3.5 Å. These stronger π–π interactions promote nonradiative decay pathways, resulting in reduced or quenched fluorescence and an aggregation-caused quenching effect. To gain further insights into their electronic properties, theoretical analysis including frontier molecular orbitals, time-dependent density functional theory, Hirshfeld surface analysis, molecular electrostatic potential, and noncovalent interaction plots were performed.","PeriodicalId":34,"journal":{"name":"Crystal Growth & Design","volume":"25 18","pages":"7473–7488"},"PeriodicalIF":3.4,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145094636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proton transfer was elucidated by analyzing molecular electrostatic potential differences at the hydrogen-bonding sites. Moreover, the formation mechanism of salts was explored through structural analyses, such as Hirshfeld surface calculations, energy framework assessments, and crystal void analysis. Considering the distinct properties of various chiral salts, we conducted competitive cocrystallization experiments, establishing a complementary chiral pairing principle that provides a theoretical foundation for cocrystallization-based chiral resolution. Based on these findings, we developed multiple processes for the separation of R- and S-mandelic acid as well as l- and d-prolinamide, achieving product purities exceeding 80%, which strongly demonstrate the feasibility of cocrystallization separation technology for chiral resolution.

Upon thermal annealing of GO, the resulting reduced graphene oxide (rGO) films exhibit spatially varying coverage, leading to three distinct GaN nucleation outcomes: (i) ELOG-like nucleation on exposed substrate regions, (ii) thru-hole epitaxy (THE)-like nucleation through appropriately thin areas, and (iii) complete nucleation suppression on thickly stacked zones. On spin-coated GO films without TBA, all three behaviors coexist, and undesired ELOG- and no-nucleation modes persist due to uneven coverage. Importantly, these issues cannot be resolved by simply adjusting GO flake concentration, as concentration tuning alone fails to eliminate the formation of locally bare and overly thick regions. In contrast, the addition of TBA results in a more uniform, moderately stacked rGO morphology that suppresses both ELOG- and no-nucleation modes while expanding THE-like nucleation regions. This reshaped nucleation landscape confines GaN growth to areas with engineered percolative transport. The approach offers a scalable, lithography-free route for controlling GaN epitaxy using solution-processable two-dimensional (2D) material masks.","PeriodicalId":34,"journal":{"name":"Crystal Growth & Design","volume":"25 18","pages":"7557–7567"},"PeriodicalIF":3.4,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145094288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Construction of such autonomous macroscopic dynamics at a molecular system level remains one of the central challenges in the field of chemistry. Looking further ahead, constructing motile systems that can receive external information and adapt their autonomous behavior represents the next frontier toward newly functional molecular devices such as microrobots. In this study, we focused on a light-driven self-oscillatory crystal that exhibits continuous flipping motion under constant light irradiation. We experimentally evaluated the oscillation frequency of the crystal under polarized light, confirmed the validity of our previously proposed mechanism, and clarified the requirements for self-oscillation. Based on this mechanism, we constructed a mathematical model that demonstrates the motion of the crystal itself. The model revealed that diverse oscillatory behaviors at the macroscopic level can arise from differences in the energy acceptance capability, even when the underlying molecular-level processes are identical. Furthermore, we found that the oscillatory behavior depended on the state generated by the previously applied light. This finding suggests that a memory effect also contributes to the adaptive and complex motion of the crystal.","PeriodicalId":34,"journal":{"name":"Crystal Growth & Design","volume":"25 18","pages":"7543–7556"},"PeriodicalIF":3.4,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145094481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
