A crosslinked polyimide copolymer having a crosslinked matrix including an R 1 group and an R 2 group, and/or an M group. The R 1 group and R 2 group independently comprise the formula:
wherein V is a tetravalent substituted or unsubstited aromatic monocyclic or polycyclic linking structure; and R is a substituted or unsubstituted divalent organic radical. R 2 structure is different than the structure for R 1 . The M group, when present, is selected from the group consisting of a diamine structure, a dianhydride structure and an end group structure, with the M group being in the reacted or unreacted form.
