HETEROAROMATIC COMPOUNDS HAVING TWO-PHOTON ABSORPTION ACTIVITY

摘要

The present invention relates to the activity that new heteroaromatic compounds have two-photon absorption. According to the present invention, the compound is suitable as activity with two-photon absorption of the optical power limit reagent by two-photon absorption or as imaging agent for two-photon laser scanning confocal fluorescence microscope. Composition comprising the compound and the intermediate for its preparation are also within the scope of the present invention.
