Electrochromic polymers film characterization

This information can be obtained using various techniques. In situ UV-vis spectroscopy, electrochemistry and sur ce studies have been used to characterize electrochromic polymer films iq>on oxidation and reduction. We present here the investigation of BBB, BBL and PPTZPQ. 

We describe die moiphologicai, electrochemical, spectroelectrochemical characterization, and electrochromic device properties of several polymer films ladder poly(benzobisiniidazobenzophenandiroline) (BBL),...

While an invaluable tool in producing conjugated polymers on conducting substrates, electropolymerization has limitations that include a lack of primary structure verification and characterization along with the inability to synthesize large quantities of processable polymer. To overcome the insolubility of PEDOT, a water-soluble polyelectrolyte, poly(styrenesulfonate) (PSS) was incorporated as the counterion in the doped PEDOT to yield the commercially available PEDOT/PSS (Baytron P) (39), which forms a dispersion in aqueous solutions [140]. While this polymer finds most of its application as a conductor for antistatic films, solid state capacitors, and organic electronic devices, its electrochromism is distinct and should not be ignored. 

Subsequent to isolation of the polymer, the metallization could be conducted in a similar manner as that of the complexes reported elsewhere for DCH-Ru complexes (27-28). The ruthenium complex polymers, shown in Figure 2, thus made would be expected to exhibit similar electrochromic properties as the dinuclear ruthenium complexes while possessing the film forming characteristics of the parent polymer. We report herein the synthesis and characterization of these polymers.
