Electronic and Ionic Transport in Processable Conducting Polymers
Abstract
A series of 2,5-distributed-1,4-bis(2-heterocycle)benzenes have been synthesized and their respective polymers have been prepared chemically and electrochemically. Good electrical conductivity has been observed for the 2,5- dimethoxy derivative where the heterocycle is thiophene when the polymer is NOPF6 doped while the 2,5-dimethyl derivative shows much lower conductivity. Correlations of the electronic properties have been made the theoretically calculated polymer band structures and minimum energy conformations. Multiangle laser light scattering molecular weight GPC studies of a number of different samples of poly(3-octylthiophene) has shown a variation from sample to sample, all being fairly high. Fibers melt spun from blends of poly(3-decylthiophene) and low density polyethylene (LDPE) have been shown by electron microscopy to be phase separated and to actually be composites of the poly(3-decylthiophene) in the LDPE matrix. We have shown that films of self-doped poly-(pyrrole propanesulfonate) tenaciously bind useful photophysical molecules. We have also demonstrated how in situ surface photochemistry at chemically modified electrodes offers a powerful route to catalyst generation at the surface.
