Abstract: Disclosed are a multi-modality molecular imaging probe, and a preparation method and use thereof. The multi-modality molecular imaging probe has an ABA structure, with a magnetic functional unit of a gadolinium complex at the center, and two identical phosphorescent functional units of an iridium complex, which are reasonably integrated into the same one complex molecule. The multi-modality molecular imaging probe simultaneously introduces two optical functional units of the iridium complex and one magnetic functional unit of a gadolinium chelate in the same one complex molecule, which exhibits magnetic-optical dual functional properties. It therefore could be used to prepare both a contrast agent for magnetic resonance imaging and an optical probe for optical imaging.
