The synthesis and characterisation of two new cyclen-based near IR-emitting lanthanide complexes are reported; the lanthanides are sensitised by rhodamine, which in turn is excited by energy transfer from a coumarin 2 moiety. Double stranded DNA selectively switches one of the two energy transfer processes off, enabling luminescent Q1 DNA-sensing in the near IR region. The regioselective di-alkylation of the cyclen scaffold is explained with the help of DFT calculations.
