摘要

多色长波长有机余辉材料在防伪领域具有重要意义,但其制备仍具有挑战性。本文以聚乙烯醇(PVA)为刚性基体,9,10-二氨基菲(DAphe)为客体分子,构建了一系列室温磷光(RTP)薄膜。令人惊奇的是,通过调整 DAphe 的掺杂含量,其 RTP 发射峰宽度可相应调整,寿命可达 3.25 秒。它们的发光特性与掺杂剂含量和激发波长有关,理论计算的结果表明,观察到的 RTP 宽发射峰可能是由客体分子聚集产生的多个发光中心造成的。有趣的是,通过掺入几种合适的荧光染料作为能量接受体,可获得从蓝色到红色的多色、长效余辉复合薄膜,在 661 纳米波长下可实现 0.42 秒的延迟荧光,荧光量子产率为 32.22%。此外,这些可调余辉材料还具有良好的成型加工性,因此可实现多种密码图案,在先进的防伪技术中具有良好的应用前景。

Ternary composite fluorescent films with tunable color and long lifetime based on efficient TS-FRET
Multi-color long-wavelength organic afterglow materials are of great significance in anti-counterfeiting, but their preparation is still challenging. In this paper, a series of room temperature phosphorescence (RTP) films were constructed with polyvinyl alcohol (PVA) as rigid matrix and 9,10-diaminophenanthrene (DAphe) as guest molecule. Surprisingly, by adjusting the doping content of DAphe, their RTP emission peak width could be adjusted accordingly, and the lifetime was up to 3.25 s. Their dopant content dependent and excitation wavelength dependent luminescence characteristics and theoretical calculation results indicated that the observed broad emission peaks of RTP might be attributed to multiple luminescence centers generated by the aggregation of guest molecules. Interestingly, by doping several suitable fluorescent dyes screened as energy acceptors, multi-color, long-lasting afterglow composite films from blue to red were obtained, achieving 0.42 s delayed fluorescence at 661 nm with a fluorescence quantum yield of 32.22 %. In addition, these adjustable afterglow materials had good molding processability, so several cryptographic patterns were achieved to demonstrate their good application prospects in advanced anti-counterfeiting technologies.
