FLUORESCEIN COLORING MATTER SUBSTITUTED WITH ELECTRON-DEFICIENT NITROGENOUS HETEROCYCLIC RING

摘要

PROBLEM TO BE SOLVED: To provide a fluorescent coloring matter compound and a bonded body thereof which are excitable by a laser beam having a long wavelength.;SOLUTION: This compound is expressed by, for example, the formula. This compound comprises at least one of such concerned donor coloring matters and acceptor coloring matters as are contained in the energy transferring coloring matter compound that is capable of absorbing a light at the first wavelength and connects by means of a linker to an acceptor coloring matter capable of absorbing an excitation energy emitted by a donor coloring matter and also contains a donor coloring matter to emit the excitation energy at the response and to fluorescence at the second wavelength at the response.;COPYRIGHT: (C)2006,JPO&NCIPI
