Abstract:
PURPOSE: A high efficiency fluorescence compound is provided to have high single photon absorption and/or two photon absorption characteristic and to not have cytotoxicity. CONSTITUTION: A high efficiency fluorescence compound is indicated in chemical formula 1. In chemical formula 1, R is substituted or unsubstituted naphthalene, substituted or unsubstituted anthracene or substituted or unsubstituted phenalene; R1 is respectively hydrogen, halogen, C1-C6 linear or branched alkyl, C3-C6 cycloalkyl, C1-C6 linear or branched alkoxy, C2-C6 heterocycloalkyl, or substituted or unsubstituted phenyl; and n is 0, 1, 2, or 3.
Abstract:
PURPOSE: A water-soluble fluorescent compound is provided to have excellent fluorescence property, to be water soluble, to contain little toxic components, to be used as a raw material for a fluorescent material. CONSTITUTION: A water-soluble fluorescent compound is indicated in chemical formula 1. In chemical formula 1, each of R^1 and R^2 is hydrogen, linear or branched C1-10 alkyl, C1-10 alkylcarbonyl, C3-6 cycloalkyl, C6-30 aryl, C5-30 heteroaryl, a water-soluble natural compound residue, or a water-soluble polymer organic compound residue. The water-soluble natural compound residue is a substituent derived from the water-soluble natural compound. The water-soluble organic compound residue is a substituent derived from the water-soluble organic polymer compound. R^1 and/or R^2 is the water-soluble natural compound residue or water-soluble polymer organic compound residue.
