MOF-based luminescent sensors have garnered considerable attention due to their potential in recognition and discrimination with high sensitivity, selectivity, and fast response in the last decades. Herein, this work describes the bulk preparation of a novel luminescent homochiral MOF, namely, Cd(-) (MOF-), from an enantiopure pyridyl-functionalized ligand with rigid binaphthol skeleton under mild synthetic condition. Except for the features of porosity and crystallinity, the MOF- has also been characterized with water-stability, luminescence, and homochirality. Most important, the MOF- exhibits highly sensitive molecular recognition toward the4-nitrobenzoic acid (NBC) and moderate enantioselective detection of proline, arginine, and 1-phenylethanol.
基于金属-有机框架(MOF)的荧光传感器在过去几十年中因其在识别和区分方面具有高灵敏度、选择性和快速响应的潜力而受到广泛关注。在此,本工作描述了一种新型手性发光同晶 MOF,即Cd(-) (MOF-),由手性吡咯基功能化的刚性联萘骨架配体在温和的合成条件下制得。除了具有多孔性和结晶性的特点外,MOF-还具有水稳定性、发光性和手性。最重要的是,MOF-对 4-硝基苯甲酸(NBC)表现出高灵敏度的分子识别,并且对脯氨酸、精氨酸和 1-苯乙醇具有中等的对映选择性检测。
