摘要

为了解决有机发光材料的宽发射光谱问题，提出了一种新颖有效的分子设计策略，通过将多共振（MR） B-N段集成到芘基骨架体系DtBuCzB-Py中来减小发射半最大值全宽度（FWHM）。利用bn -核心的窄带发射特性和平面刚性结构，得到的化合物DtBuCzB-Py不仅在甲苯溶液中具有窄带发射特性（FWHM = 25 nm）；FWHM = 38 nm)，荧光量子产率高(在甲苯溶液中ΦF = 77.2%；ΦF = 36.8%（自旋涂膜），而且自组装能力强。

High performance self-assembled pyrene-based emitter with narrowband emission and excellent luminescence efficiency†

To address the problem of broad emission spectra of organic luminescent materials, a novel and effective molecular design strategy is presented to reduce the full width at half maximum (FWHM) of emission by integrating the multi resonance (MR) B–N moiety into the pyrene-based backbone system, named DtBuCzB-Py. Taking advantages of BN-core in narrowband emission and planar rigid structure, the obtained compound DtBuCzB-Py not only exhibited narrowband emission (FWHM = 25 nm in toluene solution; FWHM = 38 nm in spin-coated film) and high fluorescence quantum yield (Φ_F = 77.2% in toluene solution; Φ_F = 36.8% in spin-coated film), but also strong self-assembly ability.
