Title: Materials for optoelectronic devices

Abstract

Energy efficient optoelectronic devices include an electroluminescent layer containing a polymer made up of structural units of formula I and II; ##STR00001## wherein R.sup.1 and R.sup.2 are independently C.sub.22-44 hydrocarbyl, C.sub.22-44 hydrocarbyl containing one or more S, N, O, P, or Si atoms, oxaalkylaryl, or a combination thereof; R.sup.3 and R.sup.4 are independently H, C.sub.1-44 hydrocarbyl or C.sub.1-44 hydrocarbyl containing one or more S, N, O, P, or Si atoms, or R.sup.3 and R.sup.4, taken together, form a C.sub.2-10 monocyclic or bicyclic ring containing up to three S, N, O, P, or Si heteroatoms; and X is S, Se, or a combination thereof.
