Supramolecular polymerization of biphenyl-cyanostilbenes. Triggering circularly polarized luminescence by self-assembly

We report on the synthesis of a series of cyano-luminogens with cyanostilbene fragments, benzamide units, and a nonplanar biphenyl core. Benzamide units drive supramolecular polymerization, forming helical H aggregates via kinetically controlled self-assembly. A sergeants-and-soldiers experiment rev...
