    Abstract

    A series of strictly a, a'-coupled oligomers of thiophene contg. 3,4,5,6,7,9, and 11 rings and provided with 0 to 5 side groups (Bu, n-dodecyl or tert-butyl) were prepd. and their m.ps., solubilities in chloroform, UV-visible absorption and emission spectra of both solns. and solids, and conductivities after doping with iodine have been measured.. The dependence of the conjugation length on the no. of rings, and on the no., length, and position of side groups is discussed. [on SciFinder (R)]
