considerable attention owing to their potential applications in optoelectronic devices, cell imaging, fluorescent sensors and so on. Hence, new aggregation induced emissive materials are in high demand. Here, we report, a series of N,C-chelated B–N coordinated tetraaryl pyrazoles (TAP-B1 to TAP-B4). The cumulative effect of the rigid organization of the phenyl groups imparts aggregation induced emissive
发光材料,尤其是聚集诱导发光材料因其在光电器件、细胞成像、荧光传感器等方面的潜在应用而备受关注。因此,对新型聚集诱导发光材料的需求量很大。在这里,我们报告了一系列 N,C 螯合的 B-N 配位四芳基吡唑( TAP-B1到TAP-B4)。苯基的刚性组织的累积效应赋予聚集诱导的发射行为,并且由 B-N 配位施加的扩展共轭使它们成为有吸引力的新聚集诱导分子。使用TAP-B4制造 CIE 为 (0.15, 0.15) 的深蓝色 OLED表现出降低的效率滚降和高达 8024 cd/m 2的出色亮度和 4.5 lm/W 和 6.1 cd/A 的显着最大 EL效率,最大外部量子效率为 4.8%。
