Mixed Oligomers Based on Biphospholes with other Hetero aromatics

Mixed Oligomers Based on Biphospholes with other (Hetero)aromatics [Pg.137]

An X-ray diffraction study of complex 52 showed that this mixed oligomer is not planar. The thiophene-thiophene, thiophene-phosphole and phosphole-phosp-hole twist angles are 6.35, 24.24 and 66.26°, respectively [43a]. Compound 51 un- [Pg.137]
