It is known that incorporating boron into the main chain of a conjugated polymer results in an electron deficient material that may behave as an n-type semiconductor.1, 2 The semiconducting properties of organoborane polymers were measured when the aryl group was fluorene.3 This current work builds upon prior studies by incorporating electron-donating or withdrawing groups onto the phenyl ring. To this end, a series of conjugated organoborane polymers, where R was H, OCH3, or F, were synthesized and characterized. In addition, optical and electrical conductivity measurements were completed with the intention that these materials will be fabricated into organic solar cells. The results of these measurements will be presented in the context of their potential use as n-type organic semiconductors.1.
