Circularly Polarized Luminescence from
Gelator Molecules: From Isolated Molecules
to Assemblies
Tonghan Zhao, Pengfei Duan, and Minghua Liu
Abstract Currently, molecular gels have become one kind of the fascinating
candidates for fabricating chiroptical materials with circularly polarized luminescence (CPL) properties, due to the tunable and modifiable structure, simple yet
facile synthesis, controlled and reversible assembly, and so on. Since self-assembly
approach has been regarded as an efficient way for amplifying the chirality, supramolecular gelation provides a remarkable method for fabricating CPL materials with
high dissymmetry factor (g lum ). Various gel systems, including chiral-, achiral-,
organic-inorganic hybrid systems can be endowed with CPL activities through
supramolecular gelatinization, possessing excellent luminescence circular polarization. This chapter summarizes and reviews the present status and progress of
supramolecular gel systems with CPL activity.
