Abstract

Abstract: Excitation hopping behavior in cY, wbis (9-anthryl)-n-alkanes (An (CH,),,, An (Am) with m= 3, 5, 7, 10, 12, 14, and 18) was explored by picosecond time-resolved fluorescence anisotropy measurements. The fluorescence anisotropy, r (t), was found to decay with time for A7, A10, A12, A14, and A18, while in a model compound, 9-ethylanthracene (EA), r (t) remained unchanged during its lifetime. Furthermore, no initial decay was observed for A3 ...
