Abstract

Conjugated polyelectrolytes, poly[2-(3-thienyl)-ethanolhydroxycarbonylmethylurethane] (HPURET) and PDA from 5,7-dodecadiyn-1,12-bis-(hydroxycarbonylmethylurethane) (HP4BCMU), were processed by programmed electrostatic assembly, respectively, with two different polycations that have significantly different refractive indices – one is poly(diallydimethylammonium) chloride (PDADMAC), the other poly(4-vinyl pyridine) quaternized with dimethylsulfate (QPVP). The optical properties of these conjugated polymers have been studied with particular attention to local environmental effects and adaption (post-assembly-processing). The electronic absorption spectra of these assemblies were dependent on the details of the assembly process.
