Inverting the Circularly Polarized Luminescence Handedness of Chiral Supramolecular Polymers Using Temperature.

ABSTRACT: The supramolecular polymerization and chiroptical properties of two enantiopure triarylamine trisamide (TATA) monomers bearing aggregation-induced emissive tetraphenylethene (TPE) units are described. A monosubstituted and a trisubstituted monomer were synthesized and their self-assembly was investigated upon either fast or slow cooling of chlorobenzene solutions. Depending on the cooling rate, two distinct fluorescent self-assemblies of opposite supramolecular chiralities were obtained from each monomer. Both the TATA and the TPE units were found to play important roles in the self-assembly process and chiroptical properties. Remarkably, the self-assembly of the monosubstituted monomer gave rise to a strong circularly polarized luminescence originating from the TATA core (g_lum
