三（8－羟基喹啉）合铝的合成和光物理行为

Synthesis and PhotophysicalBehaviour of Trioxinatoaluminium

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.
