Platinum(II) and Gold(III) Allenylidene Complexes: Phosphorescence, Self‐Assembled Nanostructures and Cytotoxicity

Abstract

The bright side of triple double bonds: Two series of stable tridentate cyclometalated PtII and AuIII allenylidene complexes were found to exhibit many functionalities, such as long‐lived excited states, self‐assembly into supramolecular nanostructures, DNA and nucleus binding and cellular imaging capabilities (see figure).

Cyclometalated Gold(III) Complexes: Synthesis, Reactivity, and Physicochemical Properties

“…[60,61] Furthermore,t he presence of strong aurophilic interactions between two discrete cationic gold complexes has also attracted increasing attention, particularly in the case of 43 e,w hich, in contrast to some of the other members of this family,p roved to be stable both as as olid as well as in solution.

Water soluble luminescent cyclometalated platinum(II) complex — A suitable probe for bio-imaging applications

“…One of the prime challenges in utilizing such complexes as probe molecule in bio- However, this complex is highly toxic (IC 50 = 11.5 µM). Che and co-workers have described [15] Pt(II)-allenylidene complex as nucleus staining, but it is also toxic (IC 50 = 19 mM …”
