Increased phosphorescence of cyclometalated Ir(III) complex with a planar triarylborane moiety upon fluoride anion binding
Abstract A luminescent Ir(III) complex functionalized with a planar triarylborane moiety was prepared. This complex exhibits unique photophysical properties derived from the electron-withdrawing effect of the triarylborane moiety. A significant change in electron density occurs upon binding of F– to the electron-deficient boron center, resulting in decreased absorption and enhanced emission.
