eng	Diphenylamino-distyrylbenzenes - solid state fluorescence behavior of various acceptors	The series of all-trans push-pull end-capped side-diphenyl substituted distyrylbenzenes (DP-DSBs) was prepared by Horner-Wadsworth-Emmons coupling and the fluorescence in polar and non-polar solvents and solid-state was studied. The design of new organic solid-state fluorophores have to bear in mind intermolecular non-radiative decay processes which affect the resulting efficiency of fluorescence in the condensed phase adversely and effective reduction of these processes is essential. The dependence of the excitation energies and reorganization accompanying excitation on the presence and electronic strength of an acceptor substituent were studied theoretically using time-dependent density functional theory.	fluorescence; distyrylbenzenes; Horner-Wadsworth-Emmons
