利用荧光法研究了甲基丙烯酸 β 萘基酯 (NMA)与咔唑 (VCZ)合成的共聚功能高分子Copolymer(NMA VCZ)的发光特性 ,结果表明 ,Copolymer(NMA VCZ)可表现出萘和咔唑两种荧光团特征的激发和发射光谱 ,但在低的浓度下 (约 10 -9mol·L-1) ,主要表现出萘环的发光特性 ,其荧光可被电子受体化合物对苯二甲酸二甲酯 (DMPT)以及电子给体化合物三乙胺 (Et3 N)所猝灭。通过对相应吸收光谱的测定 ,发现DMPT ,Et3 N均能与Copolymer(NMA VCZ)形成 1∶1的电荷转移配合物。
The luminescent properties of Copolymer Functional Polymer (NMA VCZ) synthesized from β-naphthyl methacrylate (NMA) and carbazole (VCZ) were studied by fluorescence spectroscopy. The results showed that Copolymer (NMA VCZ) There are two kinds of fluorophores: the excitation and emission spectra of the two fluorophores. However, at low concentration (about 10 -9 mol·L-1), the luminescence properties of the naphthalene ring are mainly exhibited. The fluorescence of the naphthalene ring can be excited by the electron acceptor compound terephthalic acid Dimethyl ester (DMPT) and electron donor compound triethylamine (Et3N). Through the determination of the corresponding absorption spectra, DMPT and Et3N were found to form a 1: 1 charge-transfer complex with Copolymer (NMA VCZ).
