Synthesis and photophysical properties of orthogonal rhodium(iii)–carbon bonded porphyrin–aza-BODIPY conjugates

The facile synthesis of novel orthogonally arranged Rh(iii) porphyrin–aza-BODIPY conjugates is described. The conjugates combine the advantages of the near-IR (NIR) absorption of aza-BODPY dye with the high triplet state of rhodium porphyrins.
