本論文成功合成出含有thiazolothiazole為拉電子基團之模型分子，並完成其線性與非線性光學實驗。非線性光學實驗上利用飛秒脈衝式雷射來激發模型分子，測得其螢光以實驗證明為雙光子機制所誘發之螢光，模型分子1b在800nm光源激發下具有很強的雙光子激發螢光，並在680nm到850nm之間具有良好的雙光子特性(GM> 500)，其模型分子在光學功率限幅器與光學功率穩定器之應用上具有很大的潛力。;Two new chromophores using thiazolothiazole as the electron-acceptor and diphenylaminofluorene/diphenylaminofluorene-thiophene as the electron-donor are synthesized and characterized for their linear and non-linear optical properties through corresponding methods. It is found that compound 1b exhibits strong two-photon induced fluorescence under irradiation of femtosecond laser at 800 nm. Two-photon absorption spectrum of chromophores 1b is mapped out by using two-photon excited fluorescence (2PEF) method and it is realized that this chromophore manifests intense two-photon activities (>500 GM) in the spectral range of 680-850 nm, which makes it a potential candidate for optical power-limiter or optical power-stabilizer.
