Remarkably, this chemosensor exhibits selective recognition of Zn(II) and Al(III) ions in 9:1 EtOH–water and DMSO–water media, respectively, among competing cations. Followed by an optical colour change, the presence of Zn(II) and Al(III) ions enhances the luminescence property of the probe H2L. The limit of detection for both ions is within the nanomolar range. As a practical advantage, the sensor can also be employed in several applications for easy, on-site detection, such as paper strips, cotton buds, and fluorescent ink. The chelation-enhanced fluorescence emission in the presence of two target cations is the primary reason for the increased emission intensity when both analytes are present. The probe-analyte NMR titration confirms the deprotonation of H2L and its coordination to the target metal ions. The Job's plot and mass spectral data are used to assess the stoichiometric addition of the probe to the analyte. The high binding constants obtained for the probe–analyte interactions confirm strong affinity between H2L and the target ion, which is further supported by the successful isolation and characterisation of the corresponding solid Zn(II) complex (complex 1).","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"91 7","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148443525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Single-crystal X-ray diffraction studies revealed that chromophore 2 crystallizes centrosymmetric monoclinic P21/n space group with non-covalent interactions (intermolecular hydrogen bonding and CH…π interactions), which favors SHG efficiencies. The solvatochromic studies were conducted to elucidate the intramolecular charge–transfer (ICT) process, which results in a 46 nm blueshift in the emission spectra of chromophore 2 relative to its absorption spectra, due to a higher ground-state dipole moment. The aggregation-induced emission (AIE) studies in THF/H2O mixture at 90% showed enhanced emission for chromophore 2 due to restricted intramolecular rotation (RIR). Additionally, chromophore 2 exhibited mechanofluorochromic and acidochromic behavior, which resulted in an increased emission maximum and intensity. The second-order non-linear optical (NLO) property of the chromophores was studied using Kurtz Perry powder technique, utilizing KDP as a standard reference. Chromophore 2 exhibits 1.35 times higher Second Harmonic Generation (SHG) efficiency than chromophore 1, attributed to efficient charge transfer facilitated by enhanced π-extension of the naphthalimide acceptor. Furthermore, density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations were performed to validate the experimental results using B3LYP/6-31+G** level of theory.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"91 7","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148417134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the human body may suffer serious cellular damage because of the overproduction and buildup of excess H2O2. For the detection of H2O2, the Ag2S/NiS-adhered reduced graphene oxide (Ag2S/NiS/rGO) nanozyme was developed, which oxidizes 3, 3, 5, 5-tetramethylbenzidine (TMB) into a blue-colored product, resulting in the development of an efficient and cost-effective colorimetric method. In real sample analysis, this approach showed good recovery (97.5%–100.6%) and a sensitivity to H2O2 concentrations from 0.1 to 100 mM, with the lowest limit of H2O2 observed at 0.1 mM, with Km value as low as 0.498 mM. Additionally, investigations on selectivity, storage stability (3 weeks), and recycling stability were conducted. The same nanozyme is also utilized to remove organic dyes when H2O2 is present. According to the results, methyl orange (MO) and rhodamine B (RhB) dyes decay in 8 and 6 min, respectively, with apparent rate constants of 0.02287/min for MO and 0.02132/min for RhB. This multifunctional nanozyme offers a promising platform for real-time environmental monitoring and sustainable wastewater treatment by enabling sensitive H2O2 detection and rapid degradation of hazardous organic dyes.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"91 7","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148417176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Structural confirmation was achieved via 1H NMR, 13C NMR, and FTIR, with molecular weights (Mn) determined by 1H NMR. Ultrasound-initiated styrene polymerization, yielding higher Mn and rapid conversion within 60 min, whereas free radical polymerization achieved higher overall conversion over longer times, demonstrating its time-dependent reliability. Ultrasound initiation proved ineffective for liquid crystalline acrylate polymers (P5–P8) and its copolymers (CP3–CP4), likely due to incomplete initiator activation, residual oxygen, monomer structural constraints, and equipment set up limitations, whereas free radical polymerization enabled successful synthesis (P1–P4, CP1–CP2). POM analysis of polymer P4 revealed that the nematic mesophase at 166 °C and CP2 at 106 °C. All polymers exhibited outstanding thermal stability, with 5% weight loss above 350 °C, highlighting their suitability for high-temperature processing and applications.

Different physicochemical and spectroscopic analyses confirmed the existence of cobalt(II) species as Co(OH)2 in zeolite-NaY framework. Zeolite-NaY played a pivotal role in trapping the free radicals, activating the PMS, and stabilizing the active Co(peroxo) species, Co(O–O). The involvement of Co(O–O) species in the reaction mechanism was evidenced by characteristic spectroscopic analyses, including the FTIR band at 926 cm−1 and the Raman band at 983 cm−1, attributed to the ν(O–O) vibration through Fermi resonance. The formation of cobalt(oxo)(hydroxy) complex as the intermediate redox active centre was believed to help the BA oxidation reaction to proceed through a non-free radical pathway. Noninvolvement of the free radical in the course of the reaction was evident from the electron paramagnetic resonance spectroscopic analysis. Benzaldehyde was selectively obtained up to 85% through the benzylic CH bond activation process in water making it a green reaction. Density functional theory calculations further supported the proposed mechanism, indicating that the reaction is thermodynamically favourable at 50°C in water. The catalyst exhibited good recyclability, maintaining product selectivity over three cycles.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"91 7","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148409749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inclusion of two isosteric hydrogen-bond donors led to structural diversity and different photochemical behavior when combined with trans-1,2-bis(4-pyridyl)ethylene. The realization of a three-component mixed cocrystal was achieved when combining neighboring halogen atoms such as Cl/Br and Br/I pairs. The mixed cocrystal based upon 2,4,6-trichlorophenol and 2,4,6-tribromophenol was the only mixed solid to undergo a [2 + 2] photocycloaddition reaction. The overall yield for the equal molar-mixed cocrystal lies at the midpoint between the two binary cocrystals, which demonstrates that the extent of a solid-state photoreaction can be affected using halogen exchange. The mixed cocrystal containing 2,4,6-tribromophenol and 2,4,6-triiodophenol yielded a different face-to-face π–π stacking pattern, which illustrates that the type of halogen atom can influence crystal packing. The mixed cocrystal was determined to be photostable owing to improper positioning of the carbon─carbon double bond. To test structural reliability, an additional isostructural mixed cocrystal for each system was also realized by using 1,2-bis(4-pyridyl)acetylene as a hydrogen-bond acceptor.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"91 7","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148389188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
