摘要
具有刚性连接基团的Gemini两亲分子由于其的结构特殊性,可以通过调控分子结构或者自组装的外界环境,使其组装成为一系列具有不同特性的功能材料。我们以连接基团为偶氮苯和联吡啶的Gemini两亲分子为组装单元,通过调控自组装的环境或者利用配位作用将组装单元偶联,可以制备出多种具有不同形貌的聚集体,它们分别是宏观尺度的线束和高度有序的晶体材料~(1,2)。通过对这些聚集体的进一步研究,我们发现这些聚集体具有非常良好的功能化材料特征:所得的线束是宏观尺度的分子导线,且导线的导电能力可以通过光刺激来调节;所得晶体1对有机蒸汽可以发生特异性的吸附,选择性超过2000;所得晶体2可以实现对水的选择性吸附,并且表现出晶体颜色的变化。
Contributed to the molecular design and controlling assembling environment,a series of functional materials will be performed via self-assembly.Here,two Gemini amphiphile bearing azobenzene and bipyridine groups were reported as the assembling units and the resulting aggregates are wire bundle and single crystals.It is found that wire bundle is conductive and the conductivity can be controlled by light stimulus.Besides,one of the resulting crystals shows specific adsorption toward VOC vapor and the other crystal exhibits color transition in different humidity.
