the increase of polarity of solvents, the fluorescence spectra change obviously and appear blue shift at room temperature. In addition, the light-emitting can be quenched by both electron donor (N,N-dimethylaniline, DMA) and electron acceptor (C60). When N,N-dimethylaniline is gradually added into the solution of F-MAOP, the emission intensities of fluorescence are unusually increased. But when the concentration
9,9-双[4'-[2''-苯基-5''-(3'''-(甲基丙烯酸-氨基)苯基)]-1'',3'',4''的光物理过程通过9,9-双(4'-碘苯基)芴(F-IP)与2-苯基-5- [3'-(甲基丙烯酰胺基)苯基] -1的Heck反应形成的-恶二唑基苯基]芴(F-MAOP), 3,4-恶二唑(OXD)已被仔细研究。结果表明,该化合物发出蓝光和蓝紫色光,且发射光谱显示出明显的溶剂作用。随着溶剂极性的增加,荧光光谱变化明显,在室温下出现蓝移。另外,可以通过电子给体(N,N-二甲基苯胺,DMA)和电子受体(C60)来猝灭发光。在F-MAOP溶液中逐渐加入N,N-二甲基苯胺 荧光的发射强度异常增加。但是当DMA的浓度超过一定范围时,荧光的发射强度逐渐降低。形成了F-MAOP和C60之间的双分子激基复合物,猝灭效应遵循Stern-Volmer方程。此外,还通过荧光猝灭研究了F-MAOP与碳纳米管(CNT)之间的相互作用。
