Time-resolved fluorescence anisotropy study on intramolecular interactions of branched styryl derivatives based on 1,3,5-triazine

Abstract

Abstract-A series of branched styryl derivatives based on 1, 3, 5-triazine have been studied by time-resolved fluorescence anisotropy method to study the intramolecules interferaction between branches. The obtained results further confirmed the TPA enhancement mechanism, the anisotropy of trimer shows faster decay and small residual value indicates there are strong intramolecules interactions among branches, this maybe the enhancement mechanism of TPA properties for the trimer.
