“…Flexible side chains attached to the conjugated backbone support facile deposition, improve flexibility, and increase the mobilities. Methoxy biphenyl (MeOBP) was selected as the mesogen for this study due to its thermotropic behavior with high thermal stability and lamellae forming behavior. − In previous studies of homopolymers and copolymers of MeOBP, lamellar stacking has been observed in both crystalline and smectic phases. The ability of the biphenyl moiety to undergo π stacking in the crystalline and smectic phases enables the formation of well-defined microdomains .…”

A 250 mL three neck flask with stir bar was flushed with nitrogen for 5 minutes.Tetrahydrofuran (THF) (10 mL) and 2, 5-dibromo-3-hexylthiophene (1.63 g, 5.0 mmol) were injected into the flask via syringe. t-Butylmagnesium chloride (2.5 mL, 5.0 mmol) was added into the reaction mixture and stirred for 90 minutes. Samples from the reaction mixture were taken and analyzed with GC-MS to monitor the monomer conversion. Catalyst, Ni(dppp)Cl 2 (0.04 g) (0.07 mmol) was added into the reaction mixture and stirred for 8 minutes followed by injection of allyl magnesium bromide (3 mL), (3.0 mmol) into the reaction mixture. The polymer was quenched in methanol and purified by the Soxhlet extraction with methanol,
