These factors influence the hydroxyl nucleophilicity, leading to changes in catalytic activity. To further examine substituent effects, the occupied orbital energies were calculated with several different substituent groups (-CF3, -OMe, -OH, -NH2, and -N(Me)2). It was found that the HOMO or HOMO-1 energy decreases with the increase of the σp value. Further, the catalyst activity of the [FeIII(μ-OH)ZnIIL]2+ complexes was found to be mainly affected by the phenolate ligand (B) coordinated to the iron and zinc centers. These fundamental aspects of the hydrolysis reactions of BNPP- catalyzed by [FeIII(μ-OH)ZnIIL]2+ complexes should contribute to improved understanding of the mechanism and to catalyst design involving hetero-binuclear metals complexes.We present three new hybrid layered lead(II) bromide perovskites of generic composition A2PbBr4 or AA'PbBr4 that exhibit three distinct structure types. [TzH]2PbBr4 ([TzH+] = 1,2,4-triazolium) adopts a (001)-oriented layer structure and [AaH]2PbBr4, ([AaH+] = acetamidinium) adopts a (110)-oriented type, whereas [ImH][TzH]PbBr4, ([ImH+] = imidazolium) adopts a rare (110)-oriented structure with enhanced corrugation (i.e., 3 × 3 type). The crystal structures of each are discussed in terms of the differing nature of the templating molecular species. Photoluminescent spectra for each are reported and the behaviors discussed in relation to the different structure of each composition.2D metal-organic framework (MOFs) can be ideal sacrificial templates for fabricating nanomaterials because of active sites exposed on the surface rather than in pores and channels, often exhibiting improved performance in catalysis applications. In this study, the novel 2D layered cobalt-based MOF [Co(TPT)(fma)(H2O)2]·3H2O (Co-MOF) has been cons
