中文摘要：由于银硫簇的不稳定性和有限的刺激响应特性,构建新型的具有光开关性质的银-硫簇基金属有机框架(SCC-MOF)面临着重大挑战.基于此,本文设计并合成了一种新型光致变色的SCC-MOF(Ag12-BMPTC),该材料利用二芳基乙烯配体和银硫簇前驱体通过溶剂缓慢挥发而得到.Ag12-BMPTC在365和500 nm光照射下表现出优异的可逆光响应特性.此外,这种光开关性质为其在信息加密和手性开关方面提供了潜在应用.本研究不仅扩大了SCC-MOF的种类,而且为设计和合成新型光致变色材料提供了新的思路和潜在应用.

外文标题：A fast responsive photochromic SCC-MOF for photoswitching and information encryption

外文摘要：Constructing novel photoswitch silver-chalco-genolate cluster-based metal-organic framewrorks(SCC-MOFs)presents a considerable challenge owing to their in-stability and limited stimulation-responsive properties.Herein,a novel photochromic SCC-MOF(Ag12-BMPTC)was designed and synthesized using a diarylethene ligand and an SCC.Ag12-BMPTC exhibits superior reversible photo-responsive characteristics under light irradiation(365 and 500 nm).This photoswitching behavior enables its potential applications in information encryption and chirality switches,making it as the first example of such capabilities in photo-chromic SCC-MOFs.This study not only expands the range of SCC-MOFs but also proposes a new strategy for designing and synthesizing novel photochromic materials.
