Abstract
We report a systematic approach to the control of the conjugation leng th along the poly(thiophene) backbone. The planarity of the main chain can be permanently modified by altering the pattern of substitution a nd character of the substituents on the poly(thiophene) chain, and the conjugation length is thus modified. We obtain blue, green, orange, r ed, and near-infrared electroluminescence from four chemically distinc t poly(thiophenes). The external quantum efficiencies are in the range of 0.01-0.6%.
