Heteropolynuclear cycloplatinated complexes: Structural and photophysical properties

摘要

Cyclometalated Pt~(II) complexes have drawn a lot of interest because they show interesting photolumines-cence properties with potential applications in optical materials such as OLEDs and WOLEDs. Recently, heteropolymetallic cycloplatinated complexes have also been identified as systems of interest because they readily allow emission tuning by suitable choice of heterometal, cyclometalated groups and coli-gands. This review describes the synthetic routes, structural aspects and photoluminescence properties of heteropolynuclear complexes containing cycloplatinated fragments. In turn, cycloplatinated complexes have also been investigated as molecular sensors of ions via photoluminescence responses.
