Synthesis and characterization of bis(dithiafulvenyl)-substituted fluorenones and fluorenylidene-1,3-dithioles

A series of π-conjugated oligomers containing redox-active dithiafulvenyl (DTF) end groups and fluorenone/fluorenylidene-1,3-dithiole central units was synthesized and their structural, electronic, and electrochemical properties were investigated.
