Their properties can be modulated by using a drug carrier, for example, by trapping them into a macrocyclic cavitand and releasing the metallodrug in a controlled manner. In this work, we introduce new monofunctional platinum(II) compounds with the general structure cis-[PtII(NH3)2Cl(4-R-py)]+NO3- as direct analogs of pyriplatin, cis-[PtII(NH3)2Cl(py)]+. We investigated their chemical activation by aquation in host-guest (HG) complexes with the cucurbit[7]uril (CB7) macrocycle. We used a range of NMR techniques to characterize the HG complexation in detail, and the effects of the ligand on the structure and aquation of chloride at the platinum center in the HG complexes were rationalized with the support of molecular dynamics (MD) simulations and density-functional theory (DFT) calculations. Biological screening of the cytotoxicity and the drug uptake by cell lines A2780 and A2780/CP showed that the cytotoxicity of the Pt-compound with 4-phenylpyridine and 4-pentafluorophenylpyridine ligand was comparable to that of cisplatin and that the cytotoxicity and drug uptake of the Pt-compound with a 4-(1-adamantyl)pyridine ligand was greatly modulated by the CB7 carrier. Our observations indicate great potential for HG complexes in the future supramolecular design and structural tailoring of biological activity.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142487391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these challenges, we constructed ZIF-67@CoSx/MoO3 with a core–shell structure and CoSx/MoO3 with a hollow structure as separator-modified materials for LSBs by varying the degree of sulfidation of ZIF-67. The high intrinsic conductivity of CoSx facilitated ion transfer between the cathode and separator. Additionally, the introduction of MoO3 formed a heterogeneous structure with CoSx that enhanced the adsorption of LiPSs. Via in situ UV-vis and electrochemical impedance spectroscopy testing, we demonstrated the preferred selective trapping and conversion of LiPSs by CoSx/MoO3. As a result of the synergistic effect of the bimetallic heterogeneous structure, the modified LSB exhibited excellent cycling stability, with a capacity decay rate of only 0.041% after 500 cycles at 1C. Moreover, it achieved a high discharge capacity of 632 mA h g−1 at 2C.

Although the metal clusters constructed by calixarene and its derivatives have achieved great progress, the Al clusters based on this macrocyclic ligand are still in the preliminary research stage due to the obvious hydrolysis of Al3+ ions in solution. It is a great challenge to obtain high-quality measurable single crystals of aluminum oxo clusters (AlOCs). Herein, we used an oxygen-rich organic macrocyclic ligand of p-tertbutylsulfonylcalix[4]arene (H4BTC4A-SO2) to synthesize three Al4 clusters with the formulas as Al4(OH)2(BTC4A-SO2)2(MeO)2(DMA)2(MeOH)2 (Al4-DMA∙MeOH); Al4(OH)4(BTC4A-SO2)2(DMA)4 (Al4-DMA) and Al4(OH)4(BTC4A-SO2)2(DMF)4 (Al4-DMF) which are combined by different solvents. Interestingly, the cycloaddition of carbon dioxide proves that three AlOCs with different coordinated solvents display different catalytic activities and Al4-DMF shows highest catalytic yield up to 99%. This work not only reveals three interesting calixarene-based Al cluster structures, but realize the regulation of catalytic activities for the reaction of the cycloaddition of carbon dioxide. This provides insights into the assembly of AlOCs and their study as catalyst.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142487264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the majority of existing NB-UVB phosphors rely on photoluminescence that requires constant external excitation. This common but inconvenient photoluminescence style significantly slows down the progress of NB-UVB luminescence technology. Herein, we report the design and synthesis of a new Gd3+-doped NB-UVB-emitting persistent phosphor, LiCaPO4:Gd3+, which shows strong NB-UVB persistent luminescence peaking at 312 nm and a super-long persistence time of >100 h after ceasing X-ray excitation. Owing to the zero-background noise from the ambient light, a UVB camera can detect the NB-UVB light emission originating from the charged LiCaPO4:Gd3+ phosphor in a bright indoor environment. Through spectroscopic investigations and first-principles calculations, the nature of energy traps and the persistent luminescence mechanism of Gd3+ in LiCaPO4 host have been thoroughly studied. Besides, remarkable photochromic behavior when irradiating the phosphor with X-ray is also observed, and the possible intrinsic point defects that contribute to the colorization are proposed. This NB-UVB persistent phosphor shows great potentials in indoor optical tagging, optical information storage, and dermatological therapy.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142486765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These residues are present in the active sites of crucial proteins including thioredoxin reductase. Despite extensive exploration of AF-protein interactions over the years, experimental data at the molecular level are still limited. In this work, we studied the vibrational and structural features of solvent-free complexes obtained by the reaction of AF with Cys and Sec, [(Et3P)AuCys]+ and [(Et3P)AuSec]+ ions, respectively. Using tandem mass spectrometry and IR ion spectroscopy supported by density functional theory (DFT) calculations, we unveiled markedly different behaviors for the Cys and Sec bound complexes. In particular, our results indicate that, whereas the [(Et3P)AuSec]+ ions are mainly Se-bound, in agreement with the well-known affinity of Se for gold(I), the sampled [(Et3P)AuCys]+ ionic population is composed of both N- and S-bound isomers, with their ratio depending on the dielectric constant of the solvent used in the starting solution. Additionally, we found that the deamination process occurring in the gas-phase during collision-induced dissociation experiments significantly differ between the two complexes. This work findings contribute to a deeper understanding of AF’s reactivity with Cys and Sec-containing protein targets and highlight how the chemical environment may influence target selectivity of gold-containing drugs, which is crucial for their pharmacological activities.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142487265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we propose a strategy of π-π interactions microregulating to achieve the simultaneous optimization of multiple properties of halide optical materials. Using this strategy, we obtained a new lead-free zero-dimensional (0D) zinc halide [DPE]ZnCl4 (DPE = 1,2-di(4-pyridyl)ethylene), in which the protonated DPE cations are orderly arranged via π-π interactions, facilitating the ordered embedding and local regulation of [ZnCl4]2- units within long-range one-dimensional cationic π-π stacking. As a result of these modifications, [DPE]ZnCl4 exhibits efficient blue light emission with a high photoluminescent quantum yield (PLQY) of 18.55%, far exceeding that of corresponding organic salt halides. Furthermore, this compound demonstrates enhanced third-order nonlinear optical (NLO) response, with the modulation depth and the third-order NLO absorption coefficient reaching 0.70 and 3.81 × 10-10 m W-1, respectively, surpassing those of three-dimensional (3D) perovskite quantum dots and most organic-inorganic hybrid halides. Notably, the modulation of π-π interactions results in a significant breakthrough in water resistance, allowing [DPE]ZnCl4 to maintain excellent structural and performance stability in water for a week. This innovative strategy of π-π interaction modulation provides new avenues for the multifunctional regulation and waterproof design of halide optical materials, and it is expected to advance the development and functionalization of stable halide optical materials.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142452309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through a post-synthetic modification, cysteamine (Cys) was rationally anchored onto the unsaturated Cd clusters of a pyrene-based MOF (namely WYU-11) via chemical bonds, giving rise to a modified MOF of WYU-11-Cys. This modification induced the growth of CdS nanoparticles (NPs) on the surfaces of WYU-11-Cys via the chemical bonds between CdS and Cys, resulting in the formation of MOF composite of CdS@WYU-11-Cys. The introduction of Cys could regulate the charge transfer between CdS and WYU-11, leading to the conversion from type II to Z scheme with a high redox potential of -1.93 V vs. normal hydrogen electrode. CdS@WYU-11-Cys could reduce CO2 to CO2-, which was confirmed by electron paramagnetic resonance (EPR) experiment, and promote the photocatalytic cyclization of CO2 and propargylic amines.
