The formation of coordination compounds of Ruheman's purple (RP), the reaction product of ninhydrin with amino acids, with 21 metal salts was studied with particular focus on those with fluorescent properties.
Abstract
A model explaining the structural and photophysical features that cause fluorescence of the metal-RP compounds is presented together with an interpretation of available X-ray structural and spectral data for these complexes. The data is discussed in relation to the development of ninhydrin analogs with optimal chemical and spectroscopic properties and selection of metals that will form coordination compounds with desired spectroscopic features. Lastly, the application of such complexes to latent fingerprint detection is examined. 3 figures and 2 tables (Author abstract modified)
