Abstract
The fluorescence spectra of bis(4‐methoxyphenyl) hydrogen phosphate and tris(4‐meth‐oxyphenyl) phosphate showed two emission bands. A longwavelength emission band arose from the intramolecular excimer of two 4‐methoxyphenyl groups and a short band arose from a 4‐methoxyphenyl group itself. There was a good correlation between the relative intensity of the monomer/excimer emissions and the quantum yield of 4,4′‐dimethoxybiphenyl, which was an intramolecular coupling product.
