Procedure: 10,12-pentacosadiynoic acid (10 gm, GFS Chemicals) was dissolved in a solution containing 10 ml methanol (HPLC grade) and 10 ml chloroform (HPLC grade). The solution was stirred at room temperature and 10 drops of neat sulfuric acid was added drop wise. The solution was warmed to 100° F. for 2 hour. The reaction mixture was purified using column chromatography. The product (MePDA) was dried using a rotovap and the material stored in a chloroform solution. The solid form of MePDA was very unstable to polymerization and therefore kept dissolved in organic solutions. The solution was warmed to 100° F. for 2 hour The reaction mixture was purified The product (MePDA) was dried The solid form of MePDA was very unstable to polymerization kept dissolved in organic solutions

Procedure: Alcoholic Monomer Solution of TDA/PDA: 10,12-Tricosadiynoic acid (TDA, 6 gm GFS Chemicals) and 10,12-pentacosadiynoic acid (PDA, 0.9 gm GFS Chemicals) were dissolved in 60 ml ethanol (Fisher). The solution was slightly warmed and stirred. The solution (TDA/PDA) was filtered (Whatman No. 1) to remove residual polymer. Dye colorant could be added to the alcoholic monomer solution as an indicator. Standard organic solvent based dyes were added at 2 drops per ml. The solution was slightly warmed The solution (TDA/PDA) was filtered (Whatman No. 1) to remove residual polymer Dye colorant could be added to the alcoholic monomer solution as an indicator were added at 2 drops per ml
