Microporous organic polymer nanoparticles bearing tetraphenylethylene moieties (MOPTs) were prepared in the presence of poly(vinylpyrrolidone) (PVP). The PVP was entrapped into the microporous network of MOPT to form MOPT-P and played the roles of size control, porosity enhancement, and surface property management. MOPT materials without PVP showed superhydrophobicity with a water contact angle of 151°. In comparison, the MOPT-P showed excellent water compatibility. Moreover, due to the aggregation-induced emission property of tetraphenylethylene moieties, the MOPT-P showed emission and excellent emission-based sensing of nitrophenols in water with Ksv values in the range of 1.26 × 104 ∼ 3.37 × 104 M–1. It is noteworthy that the MOPT-P used water only as a sensing medium and did not require additional organic solvents to enhance water dispersibility of materials. The MOPT-P could be recovered and reused for the sensing at least five times.

原位与水相容的聚合物包埋：一种将超疏水微孔有机聚合物转移到水中的策略
在聚 (乙烯基吡咯烷酮) (PVP) 存在下制备了带有四苯基乙烯部分 (MOPT) 的微孔有机聚合物纳米粒子。PVP被包埋在MOPT的微孔网络中，形成MOPT-P，起到尺寸控制、孔隙率增强和表面性能管理的作用。不含 PVP 的 MOPT 材料表现出超疏水性，水接触角为 151°。相比之下，MOPT-P 表现出优异的水相容性。此外，由于四苯基乙烯部分的聚集诱导发射特性，MOPT-P 对水中的硝基酚表现出发射和优异的发射传感，K sv值在 1.26 × 10 4 ∼ 3.37 × 10 4 M –1范围内. 值得注意的是，MOPT-P 仅使用水作为传感介质，不需要额外的有机溶剂来增强材料的水分散性。MOPT-P 可以回收并重新用于传感至少五次。
