一种含有咔唑基团的荧光化合物光学性能研究

Research on Optical Properties of a Novel Fluorescent Compound Containing Carbazole Group

为探究荧光化合物对pH的敏感性,采用一锅法将硝基还原成氨基,然后发生取代反应,引入酰胺键,并在咔唑部分引入苯萘基团,制备具有不对称结构的咔唑基荧光化合物,对合成的化合物进行核磁表征和光学性能测试.结果表明,具有酰胺键结构的咔唑基化合物具备一定的酸碱敏感度和聚集态诱导发射性能,并通过高斯密度泛函理论计算对实验结果进行了解释.

In order to explore the sensitivity of fluorescent compounds to pH,nitro group was reduced to amino group by one pot method, and then amide bond were formed by substitution reaction and phenylnaphthalene group was introduced into the carbazole unit to prepare carbazole-based fluorescent compound with asymmetric structure.The synthesized compounds were characterized by NMR and optical properties.The results showed that carbazole-based fluorescent compound with amide bond structure have certain acid-base sensitivity and aggregation induced emission properties, and the experimental results are explained by Gaussian density functional theory.
