  • Title: Near-infrared fluorophores containing benzo[c]heterocycle subunits.
    Author: Meek ST, Nesterov EE, Swager TM.
    Journal: Org Lett; 2008 Jul 17; 10(14):2991-3. PubMed ID: 18563902.
    Abstract:
    The syntheses and spectroscopic properties of eight new push-pull-type near-infrared fluorophores that contain either isobenzofuran or isothianaphthene subunits are presented. The isobenzofuran dyes demonstrate significantly red-shifted absorption compared with their isothianaphthene counterparts, which is attributed to isobenzofuran's more potent pro-quinoidal character.
