摘要

So far,regardless of the importance of various liquids and solutions,lots of materials with different functions should be utilized in the solid state.This is also the case for organic solids,a special kind of materials,possessing the structure of π system,with peculiar optical,electronic and magnetic properties.Actually,in addition to the modification of the π systems with different structures,their different packing states,would result in much different opto-electronic properties.However,as the π systems could inherently affect their possible packing states to regulate the material performance,the molecular design plays a key role in the research field of organic solids.Thus,once a new fundamental molecular design principle is proposed,it would evoke the rapid development of the related research fields,as demonstrated by the recent arising hot topic of AIEgens (their molecular structures are controlled as propeller shape)with the characteristic of aggregation induced emission (AIE) [1].This standpoint,somehow,might be confirmed once again by a new story initiated this April [2].
