Abstract

The four-cyclic condensed aromatic ketone 7H-benz[de]anthracene-7-one and its derivatives belong to the class of important anthraquinoid dyes, including laser and luminescent dyes. Current work is devoted to the synthesis of 3-cyanobenzanthrone and its evaluation of being a useful precursor for obtaining new 3-substituted derivatives with heterocyclic moieties, a handful of which have been synthesized up to now. The photophysical properties of the prepared compounds are investigated. The synthesized derivatives have pronounced fluorescence and are fluorescent “turn-off” probes for acidic environment. Therefore, these compounds can be used for pH sensing and as dyes in materials science and for visualization of biological structures.

摘要

四环稠合芳香酮7H-苯并[ de ]anthracene-7-one及其衍生物属于重要的蒽醌类染料，包括激光染料和发光染料。目前的工作致力于 3-氰基苯并蒽酮的合成及其作为获得具有杂环部分的新型 3-取代衍生物的有用前体的评估，其中少数已合成。研究了制备的化合物的光物理性质。合成的衍生物具有显着的荧光，是酸性环境的荧光“关闭”探针。因此，这些化合物可用于 pH 传感和材料科学中的染料以及生物结构的可视化。
