水中存在的微量染料、农药等有机分子由于无法降解或降解周期较长，日益累积已成为严重的安全问题。本课题拟合成基于吡啶醇官能团的多孔材料并研究这些材料在水相中对有机染料如甲基橙、亚甲基蓝的吸附及光催化降解反应。该类配体包括吡啶醇-羧酸，吡啶醇-双羧酸，吡啶醇-吡啶以及双吡啶醇-吡啶配体。初步的研究结果表明，吡啶醇官能团和金属离子的螯合能在水中稳定存在。通过对该类配体的反应性研究，我们预期获得一系列结构新颖、水稳定性较好且吸附和光催化性能较强的多孔吸附剂，为进一步探索此类材料的实用化打下基础。

The accumulation of trace amount of organic dyes and pesticides in water has increasingly become a safety issue as these organic molecules are hard to degrade or have slow degradation kinetics. This project proposes the preparation of a class of porous materials derived from pyridine alcohol functionalities for the adsorption and subsequent photocatalytic degradation of organic dyes such as methyl orange and methylene blue in aqueous solutions. The targeted ligands include pyridine alcohol-carboxyl, pyridine alcohol-dicarboxyl, pyridine alcohol-pyridyl and di-pyridine alcohol-pyridyl. Our preliminary results indicate that the chelation of pyridine alcohols with metal ions is stable in aqueous solutions. Through researching into the reactivity of this type of ligands, we could make a class of porous adsorbents with novel structural patterns, good water compatibility and promising photocatalytivity, thus furnishing a good entry to further explore this type of materials with an eye on their practical applications.
