摘要

不断增长的能源需求和对环境的关切促使人们加紧寻找清洁能源的解决办法。光催化水分解提供了一条很有前途的途径，但效率仍然受到对具有增强光吸收、电荷分离和水相互作用的先进光催化剂的需求的限制。多孔有机聚合物（POPs）由于其有序的共轭结构而成为太阳能转换的高效材料。本研究探讨了酮段对芴桥接双卡巴唑- violoogen基POPs （POP-MB-TP（DCzFO）和POP-MB-TP(DCzF)）亲水性和光催化析氢效率的影响。结果表明，POP-MB-TP（DCzF）的析氢速率为3.37 mmol g−1 h−1，是POP-MB-TP(DCzFO)（1.72 mmol g−1 h−1）的近两倍。这一改进突出了亲水性在电荷传输和催化效率中的作用，为设计高效的有机光催化剂用于可持续制氢提供了见解。

Hydrophilic porous organic polymers with fluorene-viologen units for enhanced photocatalytic hydrogen production

The rising energy demand and environmental concerns have intensified the search for clean energy solutions. Photocatalytic water splitting offers a promising route, yet efficiency remains limited by the need for advanced photocatalysts with enhanced light absorption, charge separation, and water interaction. Porous organic polymers (POPs) are emerging as efficient materials for solar energy conversion due to their ordered conjugated structures. This study explores the impact of a ketone moiety on the hydrophilicity and photocatalytic hydrogen evolution efficiency of fluorene-bridged bicarbazole-viologen-based POPs (POP-MB-TP(DCzFO) and POP-MB-TP(DCzF)). Our results show that POP-MB-TP(DCzF) achieves a hydrogen evolution rate of 3.37 mmol g⁻¹ h⁻¹, nearly twice that of POP-MB-TP(DCzFO) (1.72 mmol g⁻¹ h⁻¹). This improvement highlights the role of hydrophilicity in charge transport and catalytic efficiency, providing insights for designing highly efficient organic photocatalysts for sustainable hydrogen production.
