We report on the first example of alight signal photodetecting device based on the new class of neutral bis(1,2-dithiolene) complexes [M(R-dmet)(2)], whose ligand is intermediate between those belonging to the classes dmit(2-) and R,R'-timdt(2-) (dmit(2-) = 2-thioxo-1,3-dithiole-4,5-dithiolato; R,R'-timdt(2-) = N,N'-disubstituted 2-thioxoimidazoline-4,5-dithiolato; R-dmet(2-) = N-substituted 2-thioxothiazoline-4,5-dithiolato). The device, hosting the active material [Ni(Et-dmet)(2)] (1) casted on a quartz substrate, acts as a photodetector responsive in a wide spectral range, reaching the appealing near-IR region, and features the highest efficiency values as compared to those based on the dithiolene complexes [Ni(Me,Non-timdt)(2)] (2) and [Pt(Et,Pent-timdt)(2)] (3).
