Triplet Excimer Formation in a Platinum Acetylide (Preprint)

Abstract

To prove the source of ground state self-quenching in trans-Pt(P(P(C8H17)3)2(C=CC6H4C=CC6H5)2 is a result of triplet excimer formation, we carried out nanosecond transient absorption measurements on multiple concentrations. By constructing a kinetic model for the system we were able to determine rate constants for the formation and decay of the triplet excimer, 4.7 x 106 M-1s-1 and 6.9 x 105 s-1 respectively. We determined the transient absorption spectrum for the excimer which has an extinction coefficient maximum per excimer unit of 95,680 M-1cm1 at 600nm. Experimental analysis suggests that the formation of the triplet excimer is largely due to a ligand to ligand interaction.
