ABSTRACT:
Novel chalcogenopentalene compounds having a tellurium atom in the 6a position, and methods of making chalcogenopentalenes having a tellurium or a selenium atom in the 6a position are disclosed. The chalcogenopentalene compounds are useful as sensitizers in electrophotographic compositions and elements containing an electron donor and as charge emitters in multilayer photoconductive elements.
