発明の名称 (英語) RARE EARTH COMPLEX, OPTICAL IMAGING AGENT FOR RADIATION THERAPY, SCINTILLATOR FOR NEUTRON DETECTION, AND CARBORANE DERIVATIVE
発明の概要(英語) Provided is a rare earth complex which comprises one or more trivalent rare earth ions and a plurality of ligands coordinating to the rare earth ions. The plurality of ligands includes: a first ligand which has a carborane group and a coordinating group that is bonded to a carbon atom of the carborane group and is capable of coordinating to the rare earth ions; and a second ligand which has a photosensitizing action.
従来技術、競合技術の概要(英語) BACKGROUND ART
Used for image diagnosis of a living body with respect to contrast, MRI (magnetic resonance imaging) and has a function of both of optical imaging contrast of the contrast agent is a binary function has been proposed (for example, Patent Document 1).
On the other hand, composed of carbon atoms and boron atoms in the clusters having a carborane gadolinium complexes, can be used as the contrast of MRI have been reported (Non-Patent Document 1).
