| Abstract | Thiazolo[5,4-d]thiazole (TTz) was exploited as the electron-acceptor, diphenylamine as the electron-donor, and fluorene/fluorene-thiophene as the electron-bridge to create two new donor-acceptor-donor (D-A-D) type chromophores, 2DFL-TTz and 2DFL-Th-TTz. The structural characteristics of the chromophores were determined using UV spectroscopy, 1H and 13C NMR, and mass spectroscopic methods. Their linear and nonlinear optical properties were determined using Fluoromax. The outcomes showed that under femtosecond laser irradiation at 800 nm, the 2DFL-Th-TTZ compound displayed robust two-photon induced fluorescence. The two-photon excited fluorescence (2PEF) technique was employed to map the two-photon absorption spectra of 2DFL-Th-TTZ. The findings showed that this chromophore displayed strong two-photon activity (>500 GM) in the 680-850 nm spectral range, making it a possible candidate for an optical power limiter or optical power stabilizer. |
