Two new asymmetric diamines (1e2) were prepared via a facile, one-pot procedure. Based on diamine (1e2), a series of asymmetric polyimides (3e4) were prepared in NMP/xylene by high-temperature solution polymerization. The resulting polyimides are readily soluble in some organic solvents, and can be
