Solvent-regulated energy transfer efficiency and white light emitting in amphiphilic glutamide-cyanostilbene based supramolecular gel

To improve the energy transfer efficiency in chiral system is significant for natural system is composed of chiral compounds. Here, organogelator GCS based on glutamide-cyanostilbene is designed and synthesized, it is found that the gelator could form gel in both polar and non-polar solvents, show obvious circular dichroism signals. Moreover, after co-assemble with energy acceptors, the energy transfer efficiency in the two component gels could be tuned by the polarity of the solvents and white light emitting gels in polar solvents could be also obtained by modulating the molar ratio of the donor/acceptor. This work proves the external modulation such as solvent polarity is significant to the energy transfer efficiency in chiral systems.
