Bis(tetrathiafulvaleno)octadehydro[20]annulene with Multi-functionality

Sulfur-bridged octadehydro[20]annulene 1c annelated with two TTF rings was synthesized and its multi-functional properties were ascertained. The annulene exhibits paratropicity, solvatochromism, electrochromism and multi-redox potentials in solution,and its cation radical in the solid state shows self-association and electric conductivity.
