Metal Bis(1,2-dithiolene) complexes belonging to the class [Ni(Ar-edt) 2 ] x-[Ar-edt 2-= arylethylene-1,2-dithiolate; Ar = phenyl, ( 1x-), 2-naphthyl (2 x-); x = 0, 1] were fully characterized by NMR, UV-Vis-NIR, diffuse reflectance, and FT-IR spectroscopy, as well as cyclic voltammetry, and single crystal X-ray diffraction analysis. These complexes have emerged as new photoconducting materials that allowed for the development of a prototype of photodetectors with response in the Vis-NIR region. The photodetecting devices showed in some cases quantum efficiencies with orders of magnitude higher than those of previously reported 1,2-dithiolene systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
