The synthesis of novel metal chelation driven molecular pincers based on crown ether and salen ligand substructures are described. Their functionality was monitored by fluorescence spectroscopy using pyrene groups as fluorescence probes. The pincer was shown to function reversibly with respect to metal chelation with Zn2+ and also to chelate ditopically with 100 mol % of Zn2+ and 100 mol % Li+ or 200 mol % of Li+ ion.
本文描述了基于冠醚和双水杨醛缩乙二胺配体亚结构的新型金属螯合驱动分子钳的合成。使用芘基团作为荧光探针,通过荧光光谱监测它们的功能。结果表明,该分子钳在与Zn2+的金属螯合方面具有可逆功能,并且还能以100 mol%的Zn2+和100 mol%的Li+或200 mol%的Li+离子进行双位点螯合。
