Amphiphilic nanoreactors have been recently used to fabricate photoluminescent carbon‐rich polymer nanodots (PCPNs). However, the applications of PCPNs have been limited by their requirements for high temperature and toxic organic solvents or catalysts and the difficult control of their luminescent properties. Herein, a novel and facile strategy is reported for the synthesis of controllable PCPNs. This strategy involves the use of in situ vesicular nanoreactors under mild photoirradiation with fatty acid as the precursor. The conjugation degree of the uniformly sized PCPNs can be increased by extending photoreaction time, thus enabling the tuning of the optical properties of PCPNs. The PCPNs, which feature controllable and outstanding luminescent properties, low cytotoxicity, and biocompatibility, are successfully applied in bioimaging and as fluorescent ink. The present strategy is an attractive and facile platform for the preparation of carbon‐rich nanomaterials with controllable photoluminescence.

原位纳米反应器：在光辐照下衍生自脂肪酸的可控光致富碳聚合物纳米点

两亲纳米反应器最近已用于制造光致发光的富碳聚合物纳米点（PCPN）。但是，PCPNs的应用受到其对高温和有毒有机溶剂或催化剂的要求以及难以控制其发光性能的限制。在本文中，报道了用于合成可控PCPN的新颖且简便的策略。该策略涉及在以脂肪酸为前体的温和光辐照下使用原位囊泡纳米反应器。可以通过延长光反应时间来增加大小均一的PCPN的共轭度，从而可以调节PCPN的光学性能。PCPN具有可控且出色的发光特性，低细胞毒性和生物相容性，已成功应用于生物成像和荧光油墨。目前的策略是一个有吸引力且灵活的平台，用于制备具有可控光致发光的富碳纳米材料。
