Conjugated Oligomers and Polymers Based on Anthracene, Tetracene, Pentacene, Naphthodithiophene, and Anthradithiophene Building Blocks

Acene derivatives provide unique materials for organic semiconductor applications. Recent synthetic achievements have provided several oligomers and polymers based on acene building blocks of varied structural motifs, including anthracene, tetracene, pentacene, as well as naphtho- and anthradithiophene. This report highlights recent work in this area, particularly for the higher acenes tetracene, pentacene, and anthradithiophene. When possible, the properties of defined-length oligomers are compared and contrasted to those of mono- and polymeric systems.
