A novel luminescent compound 9,10-di-(N-carbazovinylene)anthracene (DCVA) was synthesized by Heck reaction of 9,10-dibromoanthracene and N-vinylcarbazole. The structure was characterized by MS, 1H NMR and Elemental analysis. The photoluminescent properties of DCVA have been carefully investigated by UV-vis absorption and fluorescence emission spectra. The results showed that the luminescent quantum yield of DCVA was 0.73 in THF and it emitted blue-light with the band gap of 3.60 eV estimated from the onset absorption. In addition, the light-emission of DCVA can be quenched by electron acceptor (dimethyl terephthalate), however, the fluorescent intensities of DCVA were slowly increased with the addition of electron donor (N,N-dimethylaniline). Furthermore, the molecular interactions of DCVA with fullerene (C60) and carbon nanotubes (CNTs) were also investigated, which indicated the organic luminescent compound can be used as new fluorescent probe.
一种新型发光化合物 9,10-二（N-咔唑乙烯基）蒽（DCVA）通过 Heck 反应由 9,10-二溴蒽和 N-乙烯基咔唑合成。通过 MS、1H NMR 和元素分析对其结构进行了表征。通过紫外-可见吸收光谱和荧光发射光谱仔细研究了 DCVA 的光致发光性能。结果表明，DCVA 在 THF 中的荧光量子产率为 0.73，其带隙为 3.60 eV，可从起始吸收估算出。此外，电子受体（二甲基对苯二甲酸酯）可以猝灭 DCVA 的发光，然而，随着电子给体（N，N-二甲基苯胺）的加入，DCVA 的荧光强度缓慢增加。此外，还研究了 DCVA 与富勒烯（C60）和碳纳米管（CNTs）的分子相互作用，表明该有机发光化合物可用作新型荧光探针。
