Abstract

2’-Hydroxychalcones of 2-cinnamoyl-4-nitro-1-naphthol series were obtained by the condensation between 2-acetyl- 4-nitro-1-naphthol and benzaldehydes. The presence of the 4-positioned nitro group in the 1-hydroxy-2-naphthyl fragment contributes to the excited state intramolecular proton transfer (ESIPT) fluorescence of these 2’-hydroxy- chalcones in the solid state. Compound with dimethyl- amino substituent, 2-(4-dimethylaminocinnamoyl)-4-nitro- 1-naphthol, also demonstrates ESIPT in solution.

2'-hydroxychalcones of 2-cinnamoyl-4-nitro-1-naphthol series 的光物理特性

通过 2-乙酰基-4-硝基-1-萘酚与苯甲醛缩合得到了 2'-羟基-2-肉桂酰基-4-硝基-1-萘酚系列的 2'-羟基查耳酮。1- 羟基-2-萘基片段中 4 位硝基的存在有助于这些 2'-羟基-查耳酮在固态下产生激发态分子内质子转移（ESIPT）荧光。具有二甲基氨基取代基的化合物 2-（4-二甲基氨基肉桂酰基）-4-硝基-1-萘酚在溶液中也显示出 ESIPT。

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
