Abstract

Synthesis of monopyrenylalkylamine derivative 1 and its fluorescence behavior for Cu2+ in H2O/CH3CN (1:1, v/v) were investigated. Upon Cu2+ binding, 1, bearing a sulfonamide group, exhibited a marked excimer emission at 455 nm along with a weak monomer emission at 375 nm. The excimer emission, driven by formation of an intermolecular pyrenyl static excimer upon Cu2+ binding to the sulfonamide group, is rationalized by experimental and theoretical DFT calculation results.

摘要

研究了单芘基烷基胺衍生物1的合成及其在H2O/CH3CN（1:1，v/v）中对Cu2+的荧光行为。在与Cu2+结合时，带有磺酰胺基团的1在455nm处呈现出明显的激基缔合物发射，同时在375nm处有微弱的单体发射。由Cu2+与磺酰胺基团结合时形成分子间芘基静态激基缔合物驱动的激基缔合物发射，通过实验和理论DFT计算结果得到了合理解释。
