A polymer comprises a polymeric chain represented by formula (I) or (II). In formula (I) a, b, d, and n are integers, a from 0 to 3, b from 1 to 5, c from 1 to 3, d from 1 to 5, and n from 2 to 5000; Rand Rare side chains; Rand Rare each independently H or a side chain; and when a is 0, Rand Rare side chains. In formula (II), a, b, c, d, e, and n are integers, a from 1 to 3, b and c being independently 0 or 1, d and e being independently 1 or 2, and n from 2 to 5000; Rand Rare side chains except &#x2014;COOalkyl; and X, Xand Xare independently O, S, or Se. Semiconductors and devices comprising the polymer are also provided. 

Polymeric semiconductors, devices, and related methods

There is presently provided compounds of formula (I), which are useful as p-type semiconductor materials and in devices comprising such p-type semiconductor materials.
