Fig. 4. Mechanochemical synthesis of Ar-BIAN ligands and the characterization of their indium and iridium complexes.

a Mechanochemical synthesis of the Ar-BIAN ligands and indium(III) complexes. b Thermal ellipsoid plots (50%) of some of the Ar-BIAN indium(III) complexes, adapted from Wang et al.³⁷, under CC BY 3.0. c Mechanochemical synthesis of an ester-modified Ar-BIAN ligand. d Calculated frontier Kohn–Sham MOs of five iridium complexes, adapted from Hasan et al.³⁸, under CC BY. The symbol for mechanical milling was proposed by Hanusa et al.⁹⁸.
