An inherently chiral C -symmetric triaminotribenzotriquinacene was condensed in racemic and enantiomerically pure form with a bis(salicylaldehyde) to form [2+3] salicylimine cage compounds. Investigations on the chiral self-sorting revealed that while entropy favors narcissistic self-sorting in solution, selective social self-sorting can be achieved by exploiting the difference in solubility between the homochiral and heterochiral cages. Gas sorption measurements further showed that seemingly small structural differences can have a significant impact on the surface area of microporous covalent cage compounds.
一种固有手性 C 对称的三氨基三苯并三嗪与双（水杨醛）缩合，以形成[2+3]水杨亚胺笼状化合物，无论是外消旋体还是对映体纯形式。对手性自分拣的研究表明，虽然熵有利于溶液中自恋的自分拣，但通过利用同手性和异手性笼之间的溶解度差异，可以实现选择性的社会自分拣。气体吸附测量进一步表明，看似微小的结构差异会对微孔共价笼状化合物的表面积产生重大影响。
