1. A polyimide precursor comprising a structural unit represented by general formula (I): in which A is a tetravalent aromatic group and B is a divalent aromatic group,
wherein B in general formula (I) comprises a triazine moiety represented by following formula (B1): in which R1 denotes hydrogen or alkyl or aryl having 1 to 12 carbon atoms, and R2 denotes hydrogen or alkyl or aryl having 1 to 12 carbon atoms, and
A in general formula (I) comprises a tetravalent residue obtainable by removing two carboxylic anhydride groups from 2,2-bis(3,4-dicarboxyphenyl)-1,1,1,3,3,3-hexafluoropropane dianhydride. |
