采用Suzuki耦合反应合成了一种新型的线性双偶极小分子红光有机电致发光材料, 即2,7-二噻吩基-9-芴酮(2,7-di(2-thienyl)fluoren-9-one, DTFO), 对其结构及电子性能进行了模拟计算, 通过各种测试方法表征了其化学结构, 并对其光物理性能、热稳定性及成膜性进行了详细表征。实验结果表明, DTFO为线性近平面交替共轭结构；在光致发光谱中, 溶液中DTFO发射的峰值波长为616 nm, 固态DTFO为 618 nm；电致发光光谱显示其发光为峰值波长为570 nm的红光发射。此外, DTFO还具有优良的热稳定性和成膜性。

A novel type of linear bipolar compound, 2,7-di(2-thienyl)fluoren-9-one (DTFO), was synthesized via Suzuki coupling reaction and was employed as a red-light organic electroluminescence material. The structure and electronic properties of DTFO were simulated; chemical structure of DTFO was identified. Moreover, its photo physical properties, thermal stability and film formability were characterized in detail. The analog results indicate that the structure of DTFO is nearly flat and linear structure with alternating conjugate. In photoluminescence spectra, DTFO exhibits a maximum emission peak at 616 nm, which emits strong red light. In addition, both the thermal stability and film formability are excellent for this novel material.
