Abstract:
A polymer comprising a first repeat unit of formula (I), wherein each Ar is independently selected from optionally substituted aryl or heteroaryl and the group of formula (I) is present in a molar ratio of less than or equal to 10%, and, optionally, a second, optionally substituted repeat unit having a single nitrogen atom in its backbone of formula —Ar—N(Ar)—Ar— in a molar ratio of no greater than 5%.
