TpBd-COFs with the different morphologies were synthesized by regulating the dynamic equilibrium of imine bond using acetic acid as a modulator. TpBd-COF nanosheet exhibits the higher photocatalytic H2 evolution activity than the TpBd-COF nanowires due to the enhanced light-harvesting ability, optimized energy levels and facilitated electron transfer.TpBd-COFs with the different morphologies were synthesized by regulating the dynamic equilibrium of imine bond using acetic acid as a modulator.

形态控制的 β-酮烯胺共价有机框架用于增强光催化制氢

以乙酸为调节剂，通过调节亚胺键的动态平衡，合成了具有不同形态的 TpBd-COFs。TpBd-COF 纳米片表现出比 TpBd-COF 纳米线更高的光催化 H2 析出活性，因为 TpBd-COF 纳米片具有增强的光捕获能力、优化的能级和促进的电子转移。以乙酸为调节剂，通过调节亚胺键的动态平衡，合成了具有不同形态的 TpBd-COFs。TpBd-COF 纳米片表现出比 TpBd-COF 纳米线更高的光催化 H2 析出活性，因为 TpBd-COF 纳米片具有增强的光捕获能力、优化的能级和促进的电子转移。
