摘要:

利用聚-(菲醌-alt-芴)(L-PPQF)中邻位羰基高效的反应活性, 将L-PPQF与乙二醇进行缩合反应, 制备了一类新型的含有菲基-螺-氧杂环的聚合物: 聚-(芴-alt-螺氧菲)(L-PPOF), 同时将L-PPQF的齐聚物二芴基-菲醌(L-DFPQ)与乙二醇反应生成二芴基-螺-氧-菲(L-DFPO). 对比L-DFPQ与L-DFPO的核磁、 质谱和元素分析, 确定了螺-氧杂环结构的生成. L-PPQF和L-PPOF的核磁和红外光谱等分析结果也证实了L-PPOF同样具有螺-氧杂环结构. L-PPOF的光物理和电化学分析结果表明, 相对于L-PPQF和商业化产品聚芴(PF), 新生成的L-PPOF具有较高的溶液和固态效率以及合适的电子注入能级. 初步的电致发光器件测试结果证明, L-PPOF在电致发光功能性材料开发领域具有一定的价值.

Abstract:

The reaction between carbonyl group in ketone or aldehyde and glycol is a class protection reaction in organic chemistry, and usually, the sprio-dioxolane structure was inserted to the original framework. In this work, the high-efficiency reaction was used between a kind of reactive polymer(L-PPQF) and glycol, because of the existence of reactive position in phenanthrenequinone block due to its ortho-carbonyl structure. A novel polymer containing sprio-dioxolane based on phenanthrene block was prepared by in situ reaction, and named L-PPOF. Collecting the results of NMR, MS and elemental analysis from the model oligomer(L-DFPQ) of L-PPQF and its product after in situ reaction, this new heterocyclic structure was confirmed. The polymer structure was also clear after chartering by the measurement in further such as NMR and FTIR. The data of photo-physical and electrochemistry show that, the newborn polymer containing sprio-dioxolane modified phenanthrene unit exhibited higher fluorescence quantum efficiency in solution and solid, more suitable electron-injection energy level than its matrix polymer L-PPQF or PF. The primary OLED performance implied the L-PPOF had good potential value.

Key words: Sprio-dioxolane polymer based on phenanthrene block, Phenanthrenequinone, Spiro, O-Containing heterocyclic, Functional, Photo-electro property
