A pair of chiral, emissive and porous tubular multi-functional organic molecular cages were synthesized easily by imine chemistry of 4,4′,4′′,4′′′-(ethene-1,1,2,2-tetrayl)-tetrabenzaldehyde (ETTBA) with (R,R)- or (S,S)-diaminocyclohexane (CHDA). It was found that the chirality of CHDA was transferred and amplified to tetraphenylethylene (TPE) in the process of formation of cages, which further endowed the cages with circularly polarized luminescence (CPL) characteristics. As a result of the synergy of the chirality and porous structure in the solid state, both cages exhibited a good chiral adsorption enantioselectivity to a series of aromatic racemates.

手性发光多孔有机笼

通过4,4',4'',4'''-(ethene-1,1,2,2-tetrayl)-的亚胺化学合成了一对手性、发光和多孔管状多功能有机分子笼。四苯甲醛 (ETTBA) 与 ( R , R )- 或 ( S , S )-二氨基环己烷 (CHDA)。发现CHDA的手性在笼的形成过程中被转移并放大到四苯乙烯（TPE），进一步赋予了笼的圆偏振发光（CPL）特性。由于手性和多孔结构在固态下的协同作用，两种笼均对一系列芳香族外消旋物表现出良好的手性吸附对映选择性。
