中止となりました。(3/14更新) Conjugated Polyelectrolytes: Fundamentals, Nanostructured Films and Solar Cell Applications

Conjugated polyelectrolytes (CPEs) are organic polymers that feature a pi-conjugated backbone that is substituted with ionic solubilizing groups. These polyfunctional materials exhibit responsive optical properties such as strong visible light absorption, coupled with the properties typical of polyelectrolytes, i.e., water solubility, surface activity and interaction with oppositely charged ions in solution. We have studied the solution properties of CPEs, focusing on their propensity to self-assemble into colloidal aggregates in water, and the interplay between the solution properties and the optical properties of the conjugated backbone. This talk will summarize fundamental work on CPEs, with emphasis on layer-by-layer films and application of CPE films in organic and hybrid solar cells.
