Interfacial materials play vital role in organic solar cell to further enhance the power conversion efficiency and stability. Here, we have synthesized various kinds of efficient ionic conjugated polyacetylene based derivatives. It is synthesized without any initiator and catalysts. The polymerization proceeded well to give product with alkyl side chains in relatively high yields. Various spectral data for the polymer structure having alkylpyridinum indicated that the conjugated polymer system substituent was formed. This ionic polymer was completely soluble in water, methanol, dimethylformamide, dimethylsulfoxide.
