Large Stokes shift induced by intramolcular charge transfer in N,O-chelated naphthyridine-BF2 complexes

Org Lett. 2012 Oct 19;14(20):5226-9. doi: 10.1021/ol302347m. Epub 2012 Oct 10.

Abstract

Novel N,O-chelated naphthyridine-BF(2) complexes with push-pull structures have been synthesized and characterized. Spectral investigations on these complexes reveal that photoinduced intramolecular charge transfer occurs and results in a large Stokes shift, which is further supported by density functional theory based theoretical calculations.
