Bi- and Terpyridine-Based Materials

PYRIDINE AND RELATED SYSTEMS A. Bi- and Terpyridine-Based Materials 

Petzold and Harruna have synthesized three-dimensional high-performance coordination polymers. A munber of these thermally stable, soluble ruthenium-coordinated polymers (47) were examined by optical spectroscopy. Solutions of rigid polyamides exhibited birefringence and the 3D polymers emitted at a Vax of 620 nm. 

The incorporation of bipyridine molecules coordinated to transition metals into the sidechains of polymers has also been utilized to tune the electronic and optical properties of polymers. Frechet and coworkers synthesized polymers incor-
