AB The recent demand for fluorescent labeled materials(FLMs) in forensic security concepts such as latent fingerprints (LFs)that encodes information for anti-counterfeiting and encryption ofconfidential data makes necessary the development of building newand innovative materials. Here, novel FLMs based on PolyhedralOligomeric Silsesquioxanes (POSS) functionalized with fluorophoresvia “click” reactions have been successfully synthesized and fullycharacterized. A comprehensive study of their photophysicalproperties has displayed large Stokes’s shift together with goodphotostability in all cases, fulfilling the fundamental requisites for anylegible LF detection on various surfaces. The excellent performanceof the hetero-bifunctional FLM in the visualization of LF is emphasizedby their legibility, selectivity, sensitivity and temporal photostability. Inthis study, development mechanisms have been proposed and theoverall concept constitute a novel approach for vis-à-vis forensicinvestigations to trace an individual’s identity.
