Iodinated Metallacrowns: Toward Combined Bimodal Near‐Infrared and X‐Ray Contrast Imaging Agents

Multimodal probes capable of combining imaging modalities within a single molecule are in high demand today as they can provide information at both molecular and anatomical levels. Herein, a study was conducted on a series of gallium(III)/lanthanide(III) bis(12‐MC‐4) metallacrowns (MCs) with the general composition {Ln[12‐MC Ga III N(shi) ‐4]} 2 (iph) 4 ( Ln‐I x , x= 0, 4, 8, 12), where shi and iph are salicylhydroximate and isophthalate...
