Pyrroles having long alkoxy groups on the β-position are prepared and utilized as precursors for polypyrrolenevinylenes. The resulting polymers exhibit high solubility not only in a moderately polar solvent but also in a nonpolar solvent such as hexane. These polymers have deep-blue color in the neutral state, while in the doped state the color is completely faded to transparent.
