A 2,1,3-benzothiadiazole-based photosensitiser has been successfully incorporated into a commercially available 3D printing resin and utilised to fabricate inherently photocatalytic flow reactor components. The freedom of design provided by additive manufacturing enabled the production of photoactive monolith structures with intricate architectures, imparting functionality for heterogeneous photocatalysis and interesting manipulation of fluid dynamics within a fixed bed reactor column. The resultant monoliths were applied and validated in the photosensitisation of singlet oxygen in aqueous media, under continuous flow conditions and visible light irradiation (420 nm). The photo-generated singlet oxygen cleanly converted furoic acid to the γ-lactone, 5-hydroxy-2(5H)-furanone, with a peak space-time yield of 2.34 mmol m⁻² h⁻¹ achieved using the Voronoi monolith.

基于2,1,3-苯并噻二唑的光敏剂已成功掺入市售3D打印树脂中，并用于制造固有的光催化流动反应器组件。增材制造所提供的设计自由度使得能够生产具有复杂结构的光敏整体式结构，从而赋予了功能以实现多相光催化以及固定床反应器塔内有趣的流体动力学控制。在连续流动条件和可见光照射下（420 nm），在水介质中单线态氧的光敏化中应用并验证了所得的整料。光生单线态氧将糠酸干净地转化为γ-内酯5-羟基-2（5H）-呋喃酮，峰-时空产率为2.34 mmol m ^-2使用Voronoi整料获得的h ^-1。
