The Stille polymerization reactions were carried out in chlorobenzene using Pd2(dba)3 and P(otol)3 for catalysis. For the work-up, the reaction mixtures were precipitated in methanol and purified by Soxhlet extraction with methanol, acetone, hexane, and -for dissolving the polymers -chloroform. The polymers were then reprecipitated in methanol, giving poly(PCT-T) and poly(PCT-2T) as yellow solids in yields of 61% and 94%, respectively. The excellent solubility observed when dissolving the polymers in CDCl3 for 1 H NMR measurements (Figures and) provided a first indication that the strategy of integrating macrocycles into the backbone of conjugated polymers to achieve solubility was successful.
