Design and synthesis of metal ion-recognition-induced conjugated polymers: An approach to metal ion sensory materials

Wang, Bing,Wasielewski, Michael R.

, p. 12 - 21 (1997)

The synthesis and metal ion responsive properties of two 2,2'-bipyridyl-phenylene-vinylene-based polymers is reported. These polymers are designed to be partially conjugated in their metal-free state and fully conjugated when exposed to metal ions so that
