Molecules containing conjugated p-electron building blocks continue as the focus of many investigations in synthesis and structure property relationships for organic electronics. Compared to these conjugated systems, organic and organometallic materials based upon substituted pentafulvenes have received little research investigation in this area. In the course of our studies on 6-substituted 1,3-diphenylfulvenes, we discovered a synthetic methodology that allows for the selective and stepwise attachment of functional substituents at the 1, 3 and 6 positions of the fulvene nucleus. This substitution pattern provides entry into the versatile design of unique new materials because the 1,3,6-trisubstituted core allows for incorporation of the fulvene skeleton into polymeric or supramolecular networks which have led into investigations of donor-acceptor properties important in electronic materials.
