Stoichiometry-controlled inversion of circularly polarized luminescence in co-assembly of chiral gelators with an achiral tetraphenylethylene derivative

A supramolecular circularly polarized luminescence (CPL) system was constructed based on the co-gelation of an achiral tetraphenylethylene derivative and chiral organic gelators of glutamic acid in chloroform. Adjusting the stoichiometric ratio was found to be an effective strategy for regulating the handedness of CPL.
