Photoluminescence (PL) of nonconjugated polymers brings a favorable opportunity for low-cost and nontoxic luminescent materials, while most of them still exhibit relatively weak emission. Strong PL from poly[(maleic anhydride)-alt-(vinyl acetate)] (PMV) from low-cost monomer has been found in organic solvents, yet the necessity of noxious solvents would hinder its practical applications. Herein, through a novel, eco-friendly, and one-step route, PMV-derived PL polymers can be fabricated with the highest quantum yield of 87% among water-soluble nonconjugated PL polymers ever reported. These PMV-derived polymers emit strong blue emission in both solutions and solids, and can be transformed into red-emission agents easily. These PL polymers exhibit application potentials in light-conversion agricultural films. It is assumed that this work not only puts forward a convenient preparation routine for nonconjugated polymers with high PL, but also provides an industrial application possibility for them.
非共轭聚合物的光致发光（PL）为低成本、无毒的发光材料带来了良好机遇，然而它们中的大多数仍表现出相对较弱的发射。已在有机溶剂中发现由低成本单体合成的聚[（马来酸酐）-alt-（醋酸乙烯酯）]（PMV）具有强烈的PL，但使用有害溶剂的必要性会阻碍其实际应用。在此，通过一种新颖、环保且一步法的路线，可以制备出PMV衍生的PL聚合物，其量子产率在迄今报道的水溶性非共轭PL聚合物中高达87%。这些PMV衍生的聚合物在溶液和固体中均发出强烈的蓝色发射，并且可以轻松转化为红色发射剂。这些PL聚合物在光转换农用薄膜中展现出应用潜力。据推测，这项工作不仅为具有高PL的非共轭聚合物提出了一种便捷的制备方法，还为它们提供了工业应用的可能性。
