Shining brightly : The synthesis, characterisation and photophysical behaviour of two new luminescent dendrimers based on ruthenium(II) dyes, carrying 32 positive ( 1 ) or 32 negative ( 2 ) charges, is described. The combination of stoichiometric control and the absence of self‐quenching of the ruthenium dyes results in a maximum increase in the fluorescence of the dendrimer corresponding to the number of substituents, and offers a straightforward and promising approach to the realisation of very bright labels.
