A new family of photoluminescent polymers with dual chromophores is prepared in this study by using poly(maleic anhydride‐alt‐vinyl acetate), acetone, and metal hydroxide. These polymers, which contain both bulky carboxylic ester groups and metal carboxylate groups, are found to be dual‐emission photoluminescent, with a blue luminescence excitation‐dependent group and a red luminescence excitation‐independent group. These photoluminescence polymers with a nonconjugated structure and dual chromophores also show characteristics of aggregation‐induced emission (AIE). The luminous intensities of the AIE fibers prepared using the polymers are found to increase after stretching, in contrast to traditional photoluminescent fibers with the aggregation‐caused quenching property. The study also finds that the stretched fibers can emit the three primary colors when irradiated by ultraviolet, blue, and green light.
