摘要
合成了三(8-羟基喹啉)合铝(Al(Ox)_3)晶体化合物,产率93.6%。测定了Al(Ox)_3的物理化学常数和光物理常数,Al(Ox)_3在芳烃溶剂中荧光量子效率较低,在非芳烃溶剂中,和荧光寿命随溶剂的粘度增加而升高。计算了辐射失活速率常数和非辐射失活速率常数的升高与k_(nr)降低相关,比较了Al(Ox)_3在不同相态介质中的荧光行为。
The solid complex trioxinatoaluminium (AI (Ox)_3) was synthesized with ayeild of 93. 6%, and its physicochemical constants and the photophysical constants weremeasured. In aromatic solvents, the fluorescence quantum yeilds(Φ_f) are low. On theother hand, Φ_f and the fluorescence lifetimes are increased in non-aromatic solvents withthe increase of the viscosity of the solvents. The radiative and nonradiative decay rateconstants (k_r and k_(nr) , respectively) were calculated and found that the increase of Φ_f wasrelated to the decrease of k_(nr). A comparison of the fluorescence behavibur of AI(Ox)_3 invarious phase media was made.
