<p>The present invention provides a polyimide compound with a branched chain group, wherein the branched chain group of the polyimide compound is R and R′, thereby increasing structural asymmetry and arrangement irregularity of the polyimide compound. The polyimide compound has the following structure formula. The branched chain group, which is R and R′, is a group selected from a group comprising:α-substituted cycloalkene having at least one tertiary carbon atom, cycloalkane with one tertiary carbon atom, cycloalkane having at least one tertiary carbon atom, phenyl,α-substituted phenyl, naphthalene,α-substituted naphthalene, phenanthrene,α-substituted phenanthrene, anthracene,α-substituted anthracene,α-substituted aromatic hydrocarbon derivative, aromatic hydrocarbon derivative, adamantine,α-substituted adamantane, diadamantene, andα-substituted diadamantene.</p> |
