A series of 9,10-bis(phenylethynyl)anthracenes decorated with sterically demanding tert-butyl substituents have been prepared and spectroscopically characterised. We demonstrate that the introduction of two bulky substituents in the ortho position of

We demonstrate that absolute measurements of the photoluminescence quantum yield of solutions can be made using an integrating sphere and a conventional fluorimeter. With this method the need for measurements against a luminescence standard is overco

Two-photon absorbing chromophores were designed and investigated for optical power limitation based on multiphoton absorption processes. These molecules combine very large two-photon absorption cross-sections (with typical σ 2p maximum values of 3
