The conversion of CO₂ to valuable solar fuels by means of solar energy using metal‐free flexible film photocatalysts is an appealing strategy. Here we demonstrate a three dimensional aromatic polymer (3DAP) derived from triptycene (TC) as a metal free, stable and highly efficient visible light responsive flexible film photocatalyst for selective solar fuel production from CO₂. For this research work, the polymerization of TC by the Diels–Alder reaction is exploited for the first time as a new synthetic approach for the construction of three dimensional aromatic polymer photocatalyst. The visible‐light harvesting ability, band gap suitability, high Brunauer–Emmett–Teller (BET) surface area and electron transfer capability via interconnecting 3D chain of 3DAP contribute to the excellent performance of the film photocatalyst as evident from 91.09 % NADH regeneration and 225.12 μmol of formic acid production. This work provides important insights into the design of flexible polymer film photocatalyst for selective solar fuel formation from CO₂ and is expected to trigger further interest in sustainable solar energy conversion applications such as tailorable and wearable devices.

原位制备的柔性3D聚合物薄膜光催化剂，用于从CO2高选择性生产太阳能燃料

使用不含金属的柔性薄膜光催化剂通过太阳能将CO ₂转化为有价值的太阳能是一种有吸引力的策略。在这里，我们演示了一种由三萜烯（TC）衍生的三维芳香族聚合物（3DAP），它是一种无金属，稳定且高效的可见光响应性柔性薄膜光催化剂，用于由CO ₂选择性生产太阳能。在这项研究中，首次利用Diels-Alder反应聚合TC作为一种新的合成方法，用于构建三维芳香族聚合物光催化剂。通过3DAP的3D链相互连接，可见光收集能力，带隙适用性，高Brunauer-Emmett-Teller（BET）表面积和电子转移能力有助于薄膜光催化剂的优异性能，从91.09％的NADH再生和225.12可见一斑。 μmol甲酸的产生。这项工作为从CO ₂选择性形成太阳能燃料的柔性聚合物膜光催化剂的设计提供了重要的见识，并有望激发人们对可持续太阳能转换应用（例如可定制和可穿戴设备）的兴趣。
