摘要：

By reaction of 1,3-dihydrobenzo[c]thiophene with FeCl3, air or TCNQ the oxidatively doped polybenzo[c]thiophenes (1a, b, d, e) were prepared. Their infrared spectra showed two strong absorptions in the ranges 1265-1337 cm-1 and 1142-1184 cm-1. Efficient drying did not change these absorptions but reaction of 1a, b, d, e with LiAlH4 resulted in their decrease to weak bands. According to these results and by comparison with the infrared spectra of reference compounds data, 1a-e were found to contain sulphone groups.
