Abstract
The solid state properties of two fluorinated pigments are compared with their unfluorinated analogues and the influence of fluoro substitution upon the solid state properties is discussed. The effect of fluorination was examined by a range of techniques including UV/visible spectroscopy, solid state NMR spectroscopy and powder X-ray diffraction. Fluorination modified the crystal packing of the molecules and subsequently altered the pigmentary performance of the compounds. In both cases fluorination gave rise to compounds with poorer fastness properties.
