چکیده انگلیسی
A new A-Ï-D-Ï-A type organoboron compound, 3,6-bis(dimesitylboryl)-N-butyl-carbazole (abbreviated as BBC), with trivalent boron as electron acceptor and carbazole as electron donor and Ï-conjugated core, has been synthesized and its single and two-photon related photophysical properties experimentally investigated. Pumped by 720Â nm laser pulses in femtosecond regime, it showed strong two-photon excited blue-violet fluorescence at 393Â nm in toluene and 403Â nm in THF. The measured two-photon absorption cross-section by two-photon fluorescence method in toluene and THF is 34Â GM and 38Â GM, respectively.
