Acid-base-induced fac → mer isomerization of luminescent iridium(iii) complexes

Kay Severin, Farzaneh Fadaei Tirani, Albert Ruggi, Anastasia Gitlina, Carolina Luciana Plaice

Luminescent Ir(C^N)3 complexes (C^N = cyclometalated arylpyridine ligand) exist in the form of two stable isomers with distinct photophysical and electrochemical properties: fac and mer. Herein, we show that fac-Ir(C^N)3 complexes can be converted into the ...
