The synthesis of ruthenium(II)-terpyridine complexes-containing glyconanoparticles (Ru-GNPs) for one- and two-photon excited fluorescence imaging was described. Ru-GNPs were built from diblock copolymers of pentafluorophenyl acrylate (PFA) and 2-(2′,3′,4′,6′-tetra-O-acetyl-尾-D-glucosyloxy)ethyl methacryalte (AcGlcEMA), prepared by reversible addition-fragmentation chain transfer (RAFT) polymerization The pendant reactive pentafluorophenyl ester groups were substituted and the copolymer cross-linked by the two-photon absorption (TPA) chromophore, bis[4′-(4-aminophenyl)-2,2′:6′,2”-terpyridyl]ruthenium(II) hexafluorophosphate. After deacetylation of the acetyl-protecting groups in the AcGlcEMA block, TPA nanoparticles with cross-linked ruthenium(II)-terpyridine complexes as the core and glycopolymers as the corona were obtained. The resulting Ru-GNPs exhibit good water dispersity, one-photon absorption and emission and low cytotoxicity towards KB cell line. Ru-GNPs also undergo two-photon excitation when excited in the near-IR (NIR, 720-880 nm) in water, with TPA cross-sections in the range of 0.2-22 G枚ppert-Mayer (GM, 1 GM = 10-50 cm4 s1 photon-1). Ru-GNPs are thus potentially useful as effective cellular labeling agents for one- and two-photon excited fluorescence imaging.
