A combined quasi-swelling and recrystallization (QSRC) approach is developed to alter distorted segments of conjugated polymer into highly ordered crystalline domains with super-long effective conjugation lengths (>100mer). These highly extended conjugated chains, at their maximum, are expected to have important implications for photonic and electronic applications and theoretical studies.The research was conducted at the NSRRC beamline 01C2.
