Abstract
A carbonyl group was positioned between 1,8-naphthalimide and di-2-picolylamine (DPA) and played a key role of displaying fluorescence enhancements with heavy and transition metal (HTM) ions through increasing the oxidation potential of the fluorophore, blocking HTM ions from sterically interacting with the naphthalimide fluorophore, and by acting as a sacrificial donor.
摘要
一个羰基基团被定位在 1,8-萘酰亚胺和二-2-吡啶基胺（DPA）之间，通过增加荧光团的氧化电位、阻止 HTM 离子与萘酰亚胺荧光团的空间相互作用，并作为牺牲供体，在与重金属和过渡金属（HTM）离子相互作用时显示出荧光增强的关键作用。
