一种新型查尔酮类荧光染料的制备及其应用

Preparation and Application of a New Chalcone Fluorescent Dye

以三苯胺和5-甲氧基-1-茚酮为原料,制备了一种查尔酮类的新型染料。通过^(1)H-NMR、^(13)C-NMR和HRMS确定了染料的结构。该物质DMSO溶液的最大吸收波长是423 nm,最大液体荧光发射波长507 nm,最大固体荧光发射波长594 nm。将其吸附在蒙脱土上制备一种荧光指纹粉,荧光显像测试表明,它在玻璃、大理石、锡纸和塑料表面能很好地显现指纹潜影。

A new type of chalcone dye was prepared from triphenylamine and 5-methoxy-1-indanone.The structure of the dye was determined by ^(1)H-NMR,^(13)C-NMR and HRMS.The maximum absorption wavelength of the dye was 423 nm in DMSO solution,its maximum liquid fluorescence emission wavelength was 507 nm,and its maximum solid fluorescence emission wavelength was 594 nm.A new type of fluorescent fingerprint powder was prepared by adsorbing it onto montmorillonite.Fluorescence imaging tests showed that it could effectively display fingerprint latent images on surfaces of glass,marble,tin foil and plastic.
