Both neutral and cationic iridium(III) complexes containing carborane units were synthesized. Bulky carboranes can significantly improve phosphorescence quantum yields of these complexes and the electronic effect of carboranes can evidently tune emission wavelengths of cationic complexes.
Phosphorescentiridium(III) complexes with three bidentate carborane‐functionalized ligands have been synthesized. The luminescent efficiency of the o‐carborane‐based facial complex fac‐o shows solvent‐molecule dependence both in solution and solid state that is related to the dielectric constant. The water‐soluble and high phosphorescence‐efficient nido complex nido‐fac‐o can be used in fluorescence

Carborane–fullerene hybrids as a seemingly attractive–attractive dyad with high hyperpolarizability
A combination between seemingly attractive carboranes and
fullerene through an ethynyl Ï-system (compounds 1aâc) gives
unexpectedly high β-values, thereby providing a guideline that in
certain cases a seemingly AâA system becomes a promising
complementary combination for obtaining high hyperpolarizability; the
β values of 1a, 1b and 1c were 346, 483, and 1189 Ã
10â30 esu, respectively.
