摘要:

本文基于水滑石类插层材料(LDHs)特有的超分子结构及其功能可调控性,采用离子交换法成功合成了邻、间、对硝基苯甲酸阴离子(o-、m-、p-NBA-)插层的锌铝水滑石,并研究了插层产物的光敏性能。插层后这3种异构体化合物都在紫外光照射下表现出不同的光响应程度,即光敏作用:m-NBA-LDH>>o-NBA-LDH≈p-NBA-LDH。用PXRD、FTIR、UV/Vis和理论计算研究了光敏性能,并提出了可能的光敏机理,为其应用于新型感光材料提供了一定的理论基础。

Abstract:

The paper describes a systematic study on the synthesis of Zn-Al layered double hydroxides (LDHs). Different guest species intercalated LDHs have been synthesized by the methods of coprecipitation and ion exchange, respectively, such as o-, m-, p-nitrobenzoic acid. PXRD, FTIR, UV/Vis and theoretical calculation were used to study the photosensitivity, and the possible mechanism was proposed, which provides a theoretical basis and a prerequisite for the application of the new photosensitive materials.

Key words: layered double hydroxides, photochromism, supramolecular structure, intercalation
