ABSTRACT

This chapter reviews the utilization of charge transfer (CT) interaction from the viewpoint of polymer chemistry, such as linear polymers connected via CT interaction, and secondary structure variation of synthetic polymer chains via CT interaction, in detail. It focuses on CT interaction from the viewpoint of polymer chemistry, thus linear polymers linked by CT interaction, and control of secondary structure of polymeric chains via CT interaction. The chapter reviews the preparation of linear polymers connected with CT interaction has been accomplished by rational molecular designs. Tetrathiafulvalene (TTF) is p-conjugated organosulfur cyclic compound possessing 14 p-electrons, and it can act as an electron donor to present CT interaction. The sandwich-type CT complex formation or the use of host molecule are essential to grow the linear polymer chains, both for accomplishing extremely high association constant and preventing infinite growth of alternating stacks to the vertical direction of the p-conjugated planes.
