Using reverse thinking of the aggregation‐induced emission (AIE) principle, we demonstrate an ingenious and universal protocol for amplifying molecular motions to boost photothermal efficiency of fibers. Core–shell nanofibers having the olive oil solution of AIE‐active molecules as the core surrounded by PVDF‐HFP shell were constructed by coaxial electrospinning. The molecularly dissolved state of AIE‐active molecules allows them to freely rotate and/or vibrate in nanofibers upon photoexcitation and thus significantly elevates the proportion of non‐radiative energy dissipation, affording impressive heat‐generating efficiency. Photothermal evaluation shows that the core–shell nanofibers with excellent durability can reach up to 22.36 % of photothermal conversion efficiency, which is 26‐fold as the non‐core–shell counterpart. Such a core–shell fiber can be used for photothermal textiles and solar steam generation induced by natural sunlight with green and carbon‐zero emission.

对聚集引起的发射原理的逆向思考：放大分子运动以提高纳米纤维的光热效率。

通过对聚集引发发射（AIE）原理的反向思考，我们展示了一种巧妙而通用的协议，用于放大分子运动以提高纤维的光热效率。通过同轴电纺丝构建以AIE活性分子的橄榄油溶液为核心，被PVDF-HFP壳包围的核-壳纳米纤维。AIE活性分子的分子溶解状态使它们能够在光激发下在纳米纤维中自由旋转和/或振动，从而显着提高了非辐射能量耗散的比例，提供了令人印象深刻的生热效率。光热评估表明，具有优异耐久性的核-壳纳米纤维可以达到光热转化效率的22.36％，是非核-壳纳米纤维的26倍。
