Abstract

A set of luminescent dyes, namely the porphyrin-ketones and their zinc(II), platinum(II) and palladium(II) complexes, are described. The probes are derived from a partially oxidized porphyrin ring and have been studied by absorption and luminescence spectroscopy including time-resolved measurements. The metal-free porphyrin-ketones display strong and pH-dependent fluorescence due to a protolytic ...
