Ultra Pseudo-Stokes Shift Near Infrared Dyes Based on Energy Transfer.

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 %.
