Abstract A glucopyranose functionalized star-shaped oligomer, N-tris {4, 4′, 4′′-[(1E)-2- (2-{(E)-2-[4-(benzo [d] thiazol-2-yl) phenyl] vinyl}-9, 9-bis (6-2-amido-2-deoxy-1-thio-β-D- glucopyranose-hexyl)-9H-fluoren-7-yl) vinyl] phenyl} phenylamine (TVFVBN-S-NH 2), is synthesized for two-photon fluorescence imaging. In water, TVFVBN-S-NH 2 self-assembles into nanoparticles with an average diameter of∼ 49 nm and shows a fluorescence ...
