Three β-substituted Ninhydrin Derivatives:Synthesis and Study on the Development of Latent Fingerprints
摘要
Abstract
The synthesis of three β-substituted ninhydrin derivatives and their application to the development of latent fingerprints on paper surfaces were investigated.Under the same concentration,the effects of β-OMe,β-NO2,β-Me ninhydrin were compared through latent fingerprint developments on different papers with multiple dimensions,respectively,and their effects were also compared with ninhydrin to analyze the advantages and disadvantages.Three β-substituted ninhydrin derivatives could develop fingerprints on different papers.The effect of β-NO2 ninhydrin was slightly inferior to the others as its solution was brown at the same time the displayed fingerprint was dark brown;the effect of β-OMe,β-Me ninhydrin was equivalent to ninhydrin in many dimensions and the sensitivity was slightly higher than ninhydrin,as well as the stability of Ruhemann's purple.The modification on β-position could change the fingerprint development effect of ninhydrin;the substitution of electron-donating groups could improve the fingerprint development effect of ninhydrin;the fluorescence performance of these compounds was not directly related to the visual effect of fingerprint display.关键词
