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 st ruct ural charact eri stics of the chromophores were determined using UV spectroscopy,1 H and13C 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. © 2024, Khon Kaen University,Research and Technology Transfer Affairs Division.
