Visible light‐driving syntheses have emerged as a powerful tool for organic synthesis and for the preparation of macromolecules under mild and environmentally benign conditions. However, precious but nonreusable photosensitizers or photocatalysts are often required to activate the reaction, limiting its practicality. Here, it is reported that poly(1,4‐diphenylbutadiyne) (PDPB) nanofibers exhibit remarkable activity in driving the living free radical polymerization under visible light. Moreover, PDPB nanofibers are very stable under irradiation of visible light and can be reused without appreciable loss of activity even after repeated cycling. The nanofiber will be a promising photocatalyst with excellent reusability and stability for the reactions driven by visible light.

聚合物纳米纤维在驱动可见光下的活性聚合和可重复使用方面表现出显着的活性

可见光驱动合成已成为有机合成和在温和且环境友好的条件下制备大分子的强大工具。然而,通常需要珍贵但不可重复使用的光敏剂或光催化剂来激活反应,限制了其实用性。据报道,聚(1,4-二苯基丁二炔)(PDPB)纳米纤维在可见光下驱动活性自由基聚合方面表现出显着的活性。此外,PDPB纳米纤维在可见光照射下非常稳定,即使在重复循环后也可以重复使用而不会明显丧失活性。纳米纤维将成为一种有前途的光催化剂,对于可见光驱动的反应具有优异的可重复使用性和稳定性。
