研究了非共轭聚喹啉铝 (Palq)在氯仿和乙醇不同极性的溶剂下所获得的薄膜的吸收和发光光谱。由于溶剂极性的不同 ,聚喹啉铝链在氯仿和乙醇溶液中表现出不同的聚集状态。当各种溶液分别旋涂成膜时 ,溶液中的聚喹啉铝的聚集态仍部分地保存下来 ,导致不同聚喹啉铝薄膜的电子结构状态的差别 ,结果 ,聚喹啉铝的薄膜表现出不同的发光特性。实验表明 ,在制作聚合物器件中 ,溶剂的选择对非共轭聚合物的发光特性有着重要的影响
The absorption and emission spectra of non-conjugated polyquinoline aluminum (Palq) films obtained under the different polar solvents of chloroform and ethanol were studied. Due to the different polarities of the solvents, the poly (aluminum chloroquine) chains show different aggregation states in chloroform and ethanol solutions. When a variety of solutions were spin-coated into films, the solution of poly-aluminum in the state of aggregation is still part of the preservation, resulting in different poly-aluminum-polyamine film electronic structure of the state of the difference, the results of poly-aluminum-aluminum film performance A different light emitting characteristics. Experiments show that in the production of polymer devices, the choice of solvent on the non-conjugated polymer luminescence properties have a significant impact
