新型螺芴类蓝光材料的合成与性能

通过一系列反应成功合成了一种新型螺芴化合物DCSF,通过核磁共振氢谱(¹H NMR)、核磁共振碳谱(¹³C NMR)、质谱(MS)、傅立叶-红外(FT-IR)光谱对其结构进行表征,利用紫外可见吸收光谱、荧光光谱研究其发光性能。以硫酸奎宁的0.05 mol/L的硫酸溶液为标准,测定其荧光量子产率为0.391。通过循环伏安曲线,计算出DCSF的HOMO和LUMO能级的能隙E_g为3.20 eV。

Synthesis and Optoelectric Properties of Novel Spirofluorene for Blue Light-emitting Materials

A type of spirofluorene, DCSF, was successfully synthesized through a series of organic reactions, and determined by ¹H NMR、¹³C NMR、MS、FT-IR. Optoelectric properties were researched by UV-Vis absorption spectra and fluorescence spectra. The photoluminescence quantum yield was measured by the relative comparison method, using quinine sulfate in 0.05 mol/L H₂SO₄ as standard, which was measured to be 0.391.The energy gap of the HOMO energy and LUMO energy was calculated through cyclic voltammeter measurement, which was estimated to be 3.32 eV.
