Tetraazatriphenylenes as Extremely Efficient Antenna Chromophores for Luminescent Lanthanide Ions

Abstract

The ability of novel tetraazatriphenylenes to sensitise the luminescence of different lanthanide ions is reported. An example of the type of lanthanide complex formed is depicted. The influence of the ligand–structure variation on the absorption characteristics and other photophysical properties of the sensitiser was investigated.
