研究了由聚喹啉铝的乙醇或氯仿溶液制备的两种薄膜发光光谱及其电致光谱。通过比较两种薄膜及其它喹啉金属配合物的光致光谱,认为这些材料发光主要来自单个喹啉,喹啉基团间的相互作用影响了喹啉基团上共轭电子的离域程度,对光谱有调节作用。聚喹啉铝中的柔性碳链和氢键产生较大位阻,能影响喹啉基团的相互作用,这是导致聚喹啉铝(Palq)发光光谱相对喹啉铝蓝移的主要原因。
The luminescence spectra and electrolysis spectra of two kinds of thin films prepared from ethanol or chloroform solution of polyquinoline aluminum were studied. By comparing the photoluminescence spectra of the two films and other quinoline metal complexes, it is considered that the luminescence of these materials mainly comes from a single quinoline. The interaction between the quinoline groups affects the degree of delocalization of conjugated electrons on the quinoline groups, Have a role in regulating the spectrum. Polycarbonates have a large steric hindrance to the flexible carbon chains and hydrogen bonds, which can affect the interaction of quinoline groups. This is the main reason that the emission spectra of Palq are shifted relative to blue.
