Two new diimine-diselenolate PtII chromophores [Pt(bipy)-(Me-dset)] (1) and [Pt(phen)(Me-dset)] (2) (Me-dset2– = Nmethyl-2-thioxothiazoline-4,5-diselenolate) were synthesized and characterized. The effect of replacing sulfur with selenium was investigated by comparing the UV/Vis spectroscopic and electrochemical properties of 1 and 2 with those of the corresponding sulfur analogues, [Pt(bipy)(Me-dmet)] (3) and [Pt(phen)(Me-dmet)] (4), with a particular focus on their linear and nonlinear optical properties.
On the role of Chalcogen Donor atoms in Diimine-Dichalcogenolate Pt(II) SONLO chromophores: is it worth replacing sulfur with selenium?

Abstract
Two new diimine-diselenolate PtII chromophores [Pt(bipy)-(Me-dset)] (1) and [Pt(phen)(Me-dset)] (2) (Me-dset2– = Nmethyl-2-thioxothiazoline-4,5-diselenolate) were synthesized and characterized. The effect of replacing sulfur with selenium was investigated by comparing the UV/Vis spectroscopic and electrochemical properties of 1 and 2 with those of the corresponding sulfur analogues, [Pt(bipy)(Me-dmet)] (3) and [Pt(phen)(Me-dmet)] (4), with a particular focus on their linear and nonlinear optical properties.
