Application of disperse dyes of the benzoxanthene-3,4-dicarboxylic anhydride type and calculation of their electronic spectra

摘要: 研究了文题染料在涤纶纤维上的染色性能。结果表明:染样色彩鲜、耐升华和耐晒牢度都较好。还研究了其最大吸收波长和最大荧光波长之间的关系,并用P.P.P.-CI分子轨道法对此类染料的最大吸收波长、最大荧光波长进行了计算。计算值和实验值有较好的一致性。

Abstract: Dyeing properties of disperse dyes of the benzoxanthene-3, 4-dicarboxylic anhydridetype on polyester fibres were studied. Prepared samples gave brilliant colors and showedgood sublimation fastness as well as the light fastness. The relationship between themaximal absorption wavelengths and the maximal fluorescent wavelengths was studied.Maximal absorption wavelengths and maximal fluorescent wavelengths of these dyes werealso calculated by the P. P. P.-CI molecular orbital method, and the calculated valuesobtained were in good consistency with the experimental ones.
