• ” reaction, has been applied to the synthesis of a range of triazole-linked porphyrin/corrole to DOTA/NOTA derivatives. Microwave irradiation significantly accelerates the reaction. The synthesis of heterobimetallic complexes was easily achieved in up to 60% isolated yield. Heterobimetallic complexes were

• are promising contrast agents (CA) in MRI. Keywords: click chemistry; corrole; DOTA; microwave; NOTA; porphyrin; Introduction Magnetic resonance imaging (MRI), positron emission tomography (PET) or single photon emission computed tomography (SPECT) are actually the most commonly used imaging

• lead to a ‘marriage of convenience’ [1]. Our group previously reported the synthesis of porphyrin-DOTA-like scaffolds for multimodal imaging [2][3]. We were interested in heterobimetallic complexes incorporating both gadolinium and copper atoms. We now want to report new multimodal porphyrinoids-DOTA
