Abstract

Host–guest chemistry represents a prominent field within many inorganic solids, where the host entity typically retains its original lattice. The hybrid composition and soft lattice of organolead halides make their structural changes and optical properties highly sensitive to host–guest interactions, distinguishing them from conventional inorganic solids. Herein, 3D electron diffraction tomography, an advanced crystallographic technique, is employed to observe the pronounced structural deformation of the lead bromide layers upon the cleavage of coordinated solvent molecules, which renders a coordination unsaturated side for the activated Pb2+ sites. Moreover, the structural transmutation induced by this process leads to a significant enhancement and red‐shift in self‐trapped emission, which is analyzed in‐depth using a variety of photophysical studies. More importantly, the activated Pb2+ centers are able to re‐coordinate with the environmental N,N‐dimethylformamide vapors in a selective and reversible manner, highlighting high application potentials in multilevel information encryption and anti‐counterfeiting.
主客体相互作用诱导卤化铅框架中明显结构变形的直接晶体学观察
主客体化学在许多无机固体中是一个突出的领域,在这些领域中,主客体通常保持其原始晶格。有机卤化铅的杂化组成和软晶格使其结构变化和光学性质对主客体相互作用高度敏感,使其区别于传统的无机固体。本文采用先进的晶体学技术三维电子衍射层析技术,观察了配合溶剂分子解理时溴化铅层的明显结构变形,使活化的Pb2+位点呈现配位不饱和侧。此外,这一过程引起的结构嬗变导致了自捕获发射的显著增强和红移,这是通过各种光物理研究进行深入分析的。更重要的是,活化的Pb2+中心能够以选择性和可逆的方式与环境中的N,N -二甲基甲酰胺蒸气重新协调,在多级信息加密和防伪方面具有很高的应用潜力。
