Abstract
Novel fluorescent dyes with ultra pseudo-Stokes Shift were prepared based on intramolecular energy transfer between a fluorescent donor and a Cyanine-7 acceptor. The prepared dyes could be excited at ~ 320 nm and emit fluorescence at ~ 780 nm. The energy transfer efficiencies of the system are found to be > 94 %.
摘要
基于荧光供体与花菁-7受体之间的分子内能量转移，制备了具有超假斯托克斯位移的新型荧光染料。所制备的染料可在约320 nm处激发，并在约780 nm处发射荧光。发现该体系的能量转移效率大于94%。
