All 7r-conjugated poly (ary lene)s change their color when electrochemically oxidized and reduced (cf. equation (5.10)). This phenomenon is called electro-chromism and much effort has been made to derive practical benefits from it [42]. For example, poly(vinyl alcohol) having PTh pendant group serves as an excellent polymer electrolyte showing electrochro-mism [43a,b] poly(vinyl alcohol) serves as an excellent...

Batteries. Many 7t-conjugated polymers can be reversibly oxidized or reduced. This has led to interest in these materials for charge-storage batteries, since polymers are lightweight compared to metallic electrodes and liquid electrolytes. Research on polymer batteries has focused on the use of polymers as both the electrode and electrolyte. Typical polymer electrolytes are formed from complexes between metal-ion salts and polar polymers such as poly(ethyleneoxide). The conductivity is low at room temperature due to the low mobility of cations through the polymer-matrix, and the batteries work more efficiendy when heated above the glass-transition temperature of the polymer. Advances in the development of polymer electrolytes have included polymers poly(ethylene oxide) intercalated into layered silicates (96). These solid-phase electrolytes exhibit significantly improved conductance at room temperature. 

The conjugated polymeric liquid crystal, poly(bis(4-methoxy-4 -hexyloxybiphenyl)dipropargylmalonate) (PMHBDPM), can be reversively doped by using electrochemical doping with the common three-electrode method utilizing acetonitrile solution containing tetrabutylammonium fluoroborate (TBAFB) as an electrolyte.
