摘要：
The conformational properties of the title compounds, which are the basic head-to-head, head-to-tail and tail-to-tail repeat units of regioregular poly(3-methylthiophenes) and poly[3-(methylsulfanyl)thiophenes], are discussed. The paper reports the X-ray structures of the two 4,4'-derivatives, H-1 NMR NOE data on the 3,4'- and 4,4'-derivatives and force field MM2 calculations of the conformation of the three bis(methylsulfanyl) derivatives.
