In recent years, nonconjugated, fluorophore‐free organic polymers have emerged as potentially useful light‐emitting materials. The fluorescence properties of a novel class of nonconjugated, tert‐butyl carboxylate functionalized stilbene‐containing alternating copolymers are investigated in this work. These sterically crowded, semi‐rigid copolymers exhibit very strong blue fluorescence in organic solvents upon irradiation. The origin of the fluorescent band with high quantum yield is attributed to the “through space” π–π interactions between the phenyl rings from the stilbene and CO groups from the anhydride groups. To the best of our knowledge, the di‐tert‐butyl group‐containing stilbene and maleic anhydride alternating copolymer showed one of the highest fluorescent intensities among all fluorophore‐free polymers. The excellent linearity of the luminescence property of this copolymer is an important attribute for future potential quantitative applications. The fluorescence is maintained when the tert‐butyl groups are removed and the resulting carboxylic acid‐functionalized copolymer is dissolved in water at neutral pH, which can render these copolymers as attractive candidates for diagnostic and therapeutic applications.

含二苯乙烯的交替共聚物的增强的荧光性质
近年来，非共轭，不含荧光团的有机聚合物已成为潜在有用的发光材料。在这项工作中，研究了一类新型的非共轭的，叔丁基羧酸酯官能化的含二苯乙烯的交替共聚物的荧光性质。这些空间拥挤的半刚性共聚物在辐照下在有机溶剂中显示出非常强的蓝色荧光。具有高量子产率的荧光带的起源归因于二苯乙烯的苯环和酸酐基团的CO基团之间的“穿越空间”π-π相互作用。据我们所知，二叔含丁基的二苯乙烯和马来酸酐交替共聚物显示了所有无荧光团聚合物中最高的荧光强度之一。该共聚物的发光性能优异的线性度是未来潜在定量应用的重要属性。当除去叔丁基时，荧光得以保持，所得的羧酸官能化共聚物在中性pH下溶于水中，这可以使这些共聚物成为诊断和治疗应用的有吸引力的候选对象。
