Abstract
The unusual NIR-photoconducting properties of [M(Et,Pent-timdt)2] neutral dithiolenes (M = Ni, Pd, Pt; Et,Pent-timdt= monoreduced N-ethyl,N′-pentylimidazolidine-2,4,5-trithione) have been investigated with the aim of developing wavelength-selective air-stable photodetectors. In addition, the ps time-resolved dynamics of the absorption saturation has been studied on the Pd-complex by means of pump-probe experiments.
