Abstract:
A polymer includes repeating unit(s) of the formula (I). a, b, c, d, e and f are 0, 1, 2, or 3. Ar1 and Ar1′ are independently of each other a group of formula (AR1). Ar2, Ar2′, Ar3, Ar3′, Ar4 and Ar4′ are independently of each other a group of formula (AR2). The polymer is preferably a co-polymer.
