Dendrimers and electronics

Polymeric (high molecular weight) semiconducting materials are expected as a key material for low cost, flexible and printable organic electronics. Especially, due to the unique and uniform molecular structure, dendritic materials have been a focus of constant attention. For example, several dendrimers that have charge transporting units at the terminal and chromophores at the core have been developed. However, laminating polymeric and dendritic materials is difficult, and the application to high-performance devices was limited. In this review, the progress of the semiconductive dendritic materials will be briefly reported, followed by the introduction of new classes of dendrimers containing phenylazomethine (for metal assembling) and carbazole (for photocrosslinking).
