Localised to intraligand charge-transfer states in cyclometalated platinum complexes: an experimental and theoretical study into the influence of electron-rich pendants and modulation of excited states by ion binding

Original language description

The neopentyl ester of 1,3-di(2-pyridyl) benzene-5-boronic acid (dpy-B) is a useful intermediate in the divergent synthesis of N<boolean AND>C<boolean AND>N-coordinating, 1,3-di(2-pyridyl) benzene ligands, HLn, that carry aryl substituents at the 5-position of the central ring. The platinum(II) complexes, (PtLCl)-Cl-n, of several such ligands have been prepared, incorporating pendant anisoles, arylamines, an oxacrown, and an azacrown, all of which are strongly luminescent in solution at 298 K. The emission of the complexes is partially quenched by oxygen, and all of the compounds are very efficient sensitisers of singlet oxygen. The quantum yields of O-1(2) formation have been measured on the basis of the intensity of the O-2 (1)Delta(g) emission at 1270 nm, and are in the range 0.25-0.65.
