摘要:

合成了苯基桥联双咔咯(1)及其镓配合物(2), 利用紫外-可见光谱(UV-Vis), 核磁共振波谱(1H NMR,19F NMR)及质谱(MS)对它们进行了表征. 采用稳态和时间分辨荧光光谱对化合物1和2的发光性质进行了研究. 实验结果表明, 双咔咯1及其镓配合物2的荧光量子产率分别为0.142和0.473, 荧光寿命相应为5.2与3.2 ns, 且配合物2的荧光光谱显著蓝移. 瞬态吸收光谱显示, 在无氧条件下双咔咯1和配合物2的三重激发态(T1)寿命分别为58与34 μs, 其T1态的量子产率则分别为0.47和0.63.

Abstract:

An m-phenyl bridged biscorrole 1 and its gallium complex 2 were synthesized and characterized by UV-Vis, 1H NMR, 19F NMR and MS. The photoluminescent properties of them were investigated using steady state and time-resolved fluorescence spectroscopy. Fluorescence quantum yield/life time of compounds 1 and 2 are 0.142/5.2 ns and 0.473/3.2 ns, respectively, and the fluorescence spectrum of compound 2 was blue-shifted significantly. Transient absorption spectroscopic investigations showed the quantum yield/life time of first excited triplet(T1) state of compounds 1 and 2 in toluene were 0.47/58 μs and 0.63/34 μs respectively.

Key words: Biscorrole, Gallium, Fluorescence, Transient absorption spectrum
