  Abstract

Polypyrrole nanobelts (PNBs) were synthesized through an organic single-crystal surface-induced polymerization (OCSP) method utilizing single crystals of 5-sulfoisophthalic acid sodium salt (5-SINa) in acetonitrile, a polar aprotic organic solvent. The OCSP technique enables the polypyrrole to grow along the surface of the organic crystals, replicating their needle-like morphology. This shape-copying approach results in highly anisotropic PNBs with significantly improved structural order and surface area. Compared to conventionally synthesized polypyrrole, the PNBs exhibited enhanced π- stacking interactions and a higher doping level, which collectively contributed to a notable electrical conductivity of 21.3 S/cm, approximately seven times higher than that of polypyrrole fabricated without the use of organic single crystals. The OCSP process in acetonitrile also offers advantages such as a fast reaction rate, low processing cost, and high product yield, making it suitable for scalable manufacturing. To evaluate their electrochemical performance, the PNBs were employed as counter electrodes in dye-sensitized solar cells (DSSCs). The resulting devices demonstrated high optical transmittance and an overall energy conversion efficiency reaching 75% of the standard platinum-based cells. These findings highlight the potential of PNBs as a cost-effective and flexible alternative to noble metal-based materials for next-generation optoelectronic and energy devices.
