The synthesis of dyes based on a highly substituted terephthalic acid core is described, starting from readily available 2,5-dihydroxy-terephthalic acid diethyl ester. The dyes are highly colored, soluble in organic solvents and reasonably fluorescent in solution and in the solid state. The maxima for absorption and emission are around 402 and 502 nm, respectively. The fluorophores are readily cyclized
从容易获得的2,5-二羟基对苯二甲酸二乙酯开始,描述了基于高度取代的对苯二甲酸核心的染料的合成。染料是高度着色的,可溶于有机溶剂,并且在溶液和固态下均具有适当的荧光性。吸收和发射的最大值分别约为402和502 nm。荧光团容易环化以产生包含碱性6,13-二羟基-铬诺[2,3 - b ] x吨-7,14-二酮单元的化合物。这些新的衍生物是非荧光的。
