instance, strained cyclic π-conjugated molecules: substituted [8]cycloparaphenylene-triphenylenes ([8]CPPTs) via intermolecular cycloaromatization routes . Certain CPPTs like 5b and 12 showed distinct AIE properties (Figure and 11f), with their AIE behavior attributable to restricting the rotational and twisting behavior of the triphenylene moiety. In reality, the AIE mechanisms of many macrocyclic molecules need to be explained by both RIV and RIR mechanism . In addition to the rotation of the phenyl ring, the vibration of structures such as pyrazine , imidazolium , thiophene , and pyrrolyl in the cyclic system can also partially explain the enhanced aggregation-induced emission.
