Two-photon absorbing dendrimer and manufacturing method thereof

摘要

hydroxy end groups of the present invention is a compound having the formula (1) show that the core dendritic benzyl halide (dendrictic benzyl halide) provides a dendritic polymer and a manufacturing method obtained by the coupling reaction of. ; [Formula 1] ; the formula, X is Br, Cl, or I. Dendritic structure of the present invention can be attached to a two-photon fluorescent dyes in order to control the sikhim (fluorescence quenching) caused by aggregation (aggregation) of the pigment in question in the two-photon compound - electron structure controlling intermolecular interactions a two-photon absorbing dye of, Frechet- type of dendron is bonded to the two-photon dyes dendrimer film even on a solid solution state, as well as high fluorescence efficiency of the photon emission is also increased due to the aggregation between the dye in the dye itself excitons (excimer) formed effectively controlling the separation site (site isolation) is greater the effect.
