A theoretical investigation on the electronic structure of 4-dimethylamino-4'-nitrostilbene (DANS), 4-(dicyanomethylene)-2-methyl-6-p-(dimethylamino) styryl-4H-pyran (DCM), and their protonated forms is presented in an effort to rationalize recent experimental results on the tuning of the emitted color of organic light-emitting diodes through photochemically

External electric field effects on state energy and photoexcitation dynamics have been examined for para-substituted and unsubstituted all-trans-diphenylpolyenes doped in a film, based on the steady-state and picosecond time-resolved measurements of the field effects on absorption and fluorescence. The substitution

The capability of ammonium 18-molybdodiphosphate, (NH(4))(6)P(2)Mo(18)O(62) (Mo(18)(6-)), and ammonium 18-tungstodiphosphate, (NH(4))(6)P(2)W(18)O(62) (W(18)(6-)), to photochemically generate acid within films of a polymer with hydroxylic functional groups (namely, within poly(2-hydroxyethyl methacrylate) (PHEMA) films) is demonstrated. Upon UV irradiation, both 2:18 polyoxometalates (POMs)
