四个具有螺环结构特征的三维结构分子1a-d被开发。1a和1b由于其刚性的三维结构，通过旋涂形成均匀且无定形的薄膜。1a-d的PL光谱在空气退火后表现出优异的热稳定性。在空气中200 ℃连续退火12小时后，其蓝色仍保持完整. OLED制造表明，所有1a-d在不同的工作电压下都表现出纯蓝色EL性能和良好的颜色完整性。
Four three-dimensionally architectured molecules 1a-d with spiro-annulated structural features were facilely developed. 1a and 1b form uniform and amorphous films via spin-coating due to their rigid three-dimensional architecture. The PL spectra of 1a-d exhibit 0 excellent thermal stability upon air annealing. Their blue color integrity remained after continuous annealing for 12 h at 200 C in the air. OLED fabrication reveals that all 1a-d exhibit pure blue EL performance and good color integrity at different operating voltages.
