在有机发光二极管（OLED）的研究中经常提到共轭体，但直接使用现成的共轭体作为荧光探针几乎没有报道。本文首次将基于4,4′，4″-三（n -咔唑基）三苯胺（TCTA）和1-苯基- 1H-苯并[d]咪唑- 1,3,5 -三嗪（PIM-TRZ）组成的荧光配合物f1作为有机胺蒸气的荧光膜探针。f1膜可以准确识别苯胺（AN）和n -甲基苯基乙胺（MPEA，甲基苯丙胺的一种模拟物）蒸气，并可以通过不同的输出信号轻松大致区分脂肪胺和芳香胺蒸气：AN蒸气使f1膜的荧光猝灭，并伴有明显的红移光致发光（PL）光谱，常见的脂肪族胺蒸气使TCTA的发射峰出现，而常见的芳香胺蒸气仅使f1膜的荧光部分猝灭。据我们所知，这是第一个多功能荧光探针，可以同时在多种胺中高度识别AN和MPEA蒸气。因此，本研究为AN和MPEA的精确荧光多功能探针和有机胺蒸汽荧光传感器的构建提供了新的策略。并对荧光复合物的新应用进行了探讨。
Exciplexes are often mentioned in the research of organic light-emitting diode (OLED), but there are nearly no reports using the ready-made exciplexes as fluorescent probes directly. In this work,F1based on the fluorescent exciplex composed of 4, 4′, 4″- tris (N-carbazolyl) triphenylamine (TCTA) and 1- phenyl- 1H- benzo[d]imidazole −1, 3, 5- triazine (PIM-TRZ) is firstly applied as fluorescent film probe to organic amine vapors. TheF1film can accurately identify aniline (AN) and N-methylphenethylamine (MPEA, a simulant of methamphetamine) vapors, as well as roughly distinguish aliphatic and aromatic amine vapors easily by different output signals: the AN vapor causes an instantaneous and entire fluorescence quenching, MPEA vapor leads to the fluorescence quenching of theF1film along with obvious red-shifted photoluminescence (PL) spectrum, the common aliphatic amine vapors bring the emergence of emission peak of TCTA, and the common aromatic amine vapors only result in partial fluorescence quenching of theF1film. To the best of our knowledge, it is the first multifunctional fluorescent probe to highly identify AN and MPEA vapors simultaneously among various amines. Hereby, the study provides both promising accurate fluorescent multifunctional probe to AN and MPEA and new strategy for the construction of fluorescent sensors to organic amine vapors. Moreover, the new application of fluorescent exciplex is explored.
