Abstract:
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 revealed frustrated asymmetry amplification due to the contamination of linear dichroism. The planarization of the central π-conjugated systems enhances aggregation-induced emission affording circularly polarized luminescence-active helical aggregates.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
