Abstract

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.

摘要

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。
