Four chiral 1,2-diaminocyclohexane (DACH)-based molecules (R,R/S,S-2 and R,R/S,S-4) incorporating 1,8-naphthalimide fluorophores exhibit strong circularly polarized luminescence (CPL) emission signals in common organic solvents. Interestingly, the reversed CPL signals can be observed in the aggregated state, which is due to the orderly aggregation.
四种基于手性1,2 - 二氨基环己烷（DACH）并含有1,8 - 萘二甲酰亚胺荧光团的分子（R,R/S,S - 2和R,R/S,S - 4）在常见有机溶剂中表现出强烈的圆偏振发光（CPL）发射信号。有趣的是，在聚集态中可以观察到相反的CPL信号，这是由于有序聚集所致。
