Abstract

Organic nanoparticles provide exceptional intraparticle tailorability, enabling the incorporation of functional molecules for diverse applications. In this study, we present the synthesis and characterization of fluorescent organic nanoparticles (FoNPs) with encapsulated aggregation-induced emission (AIE) luminogens with emission properties regulated by particle rigidity. Atom transfer radical polymerization (ATRP) was employed in dispersed media to develop various fluorescence colors tuned by precise control over particle rigidity. Comprehensive analyses revealed that increased particle rigidity significantly enhanced photoluminescence, achieving quantum yields of up to 22% in selected solvents. The high chain-end fidelity facilitated the grafting of hydrophilic polymer brushes from surfaces of FoNPs used as macroinitiators, enabling their dispersion in aqueous media while maintaining bright fluorescence. These findings highlight the potential of rigidity-regulated FoNPs as versatile platforms for advanced material applications, particularly in fluorescent waterborne films and aqueous-phase sensing systems.

刚体调控发射的电刷修饰有机荧光纳米颗粒

有机纳米颗粒提供了卓越的颗粒内可定制性，使各种应用的功能分子的结合成为可能。在这项研究中，我们提出了具有封装聚集诱导发射（AIE）发光原的荧光有机纳米颗粒（FoNPs）的合成和表征，其发射特性由颗粒刚度调节。原子转移自由基聚合（ATRP）是一种在分散介质中通过精确控制粒子刚度来产生各种荧光颜色的方法。综合分析表明，增加的颗粒刚度显着增强了光致发光，在选定的溶剂中实现了高达22%的量子产率。高链端保真度有利于亲水性聚合物刷从用作宏观引发剂的FoNPs表面接枝，使其在水介质中分散，同时保持明亮的荧光。这些发现突出了刚度调节fonp作为先进材料应用的多功能平台的潜力，特别是在荧光水性薄膜和水相传感系统中。

期刊介绍： Chemical Science is a journal that encompasses various disciplines within the chemical sciences. Its scope includes publishing ground-breaking research with significant implications for its respective field, as well as appealing to a wider audience in related areas. To be considered for publication, articles must showcase innovative and original advances in their field of study and be presented in a manner that is understandable to scientists from diverse backgrounds. However, the journal generally does not publish highly specialized research.
