摘要

合成了一种具有深的HOMO （-6.15 eV）分子轨道和高三线态能级（T

，2.82 eV）的新型化合物10-（2-螺-9，9'-氧杂蒽芴基）吩噻嗪（SFXPz）。因其宽的能带结构（

，4.22 eV）和深的HOMO能级而有望制备高效蓝色有机电致磷光器件。热重分析和差热扫描曲线表明，该化合物具有良好的热稳定性（

，259℃）和高的形态稳定性（

，206℃）。完全相互分离的HOMO和LUMO轨道有利于阻止分子内能量反转。SFXPz的紫外吸收峰分别位于230，260，292和310 nm左右；其荧光光谱两个发射峰分别位于311，324 nm左右。此外，该化合物的分子结构经LC-MS、

H NMR和

C NMR进行了详细表征。

Abstract

A novel 10-(spiro[fluorene-9

9'-xanthen]-2-yl)-phenothiazine(SFXPz) with deep HOMO(the highest occupied molecular orbital)(-6.15 eV) and high triplet energy(T

2.82 eV) has been synthesized

which is expected to fabricate high-efficient blue phosphorescent organic light-emitting diodes(PhOLEDs) due to the importance of a wide energy gap(

4.33 eV) and deep enough HOMO in blue PhOLEDs. The good thermal stability(

259℃) and high stable morphology(

206℃) of SFXPz were demonstrated by thermo gravimetric analysis(TGA) and differential scanning calorimetry(DSC) curves. The complete separation of HOMO and the lowest unoccupied molecular orbital(LUMO) of the compound is preferable to prevent the back of energy transfer. The UV-Vis spectrum peaks of SFXPz exhibit at around 230

260

292

310 nm

respectively

and the corresponding fluorescence emission spectrum peaks show at about 311

324 nm

respectively. In addition

the molecular structure is characterized detailedly by LC-MS

H NMR and

C NMR

respectively.
