Combinatorial optical screening of aprotic electrocatalysts has not yet been achieved primarily due to H-associated mechanisms of fluorophore modulation. We have overcome this problem by using fluorophore metal-organic complexes. In particular, eosin Y and quinine can be coordinated with various metallic cations (e.g., Li, Na, Mg, Zn, and Al) in aprotic solvents, triggering changes in their fluorescent properties. These interactions have been used in a reliable screening method to determine oxygen reduction/evolution reaction activities of 100 Mn-based binary catalysts for the aprotic Li-air battery.
非质子型电催化剂的组合光学筛选尚未实现，主要原因是荧光团调制存在与氢相关的机制。我们通过使用荧光团金属有机配合物克服了这个问题。特别是，曙红Y和奎宁可以在非质子溶剂中与各种金属阳离子（如锂、钠、镁、锌和铝）配位，引发其荧光性质的变化。这些相互作用已被用于一种可靠的筛选方法，以确定用于非质子型锂空气电池的100种锰基二元催化剂的氧还原/析出反应活性。
