Abstract
Disclosed are semiconducting or conducting organic small molecules and oligomers that contain a central, electron rich, functionalized dihydrodicyclopentylanthracene core (or electron donor core) that is connected to at least one or two comparatively electron deficient monomeric unit or units (or electron acceptor units) that feature group 16 heteroatoms sulfur, selenium or tellurium or combinations thereof. Multiple electron rich cores can be linked together through one or more alkynyl linkages. The small molecules and oligomers can have the following generic structure and can be used in areas such as organic photovoltaic materials:
