We wish to report here on the synthesis of organometallic complexes utilizing a stable and readily available red fluorophore with convenient linker groups, and demonstrate organometallic chemistry applications of a new green-red FRET pair with excellent chemical and photochemical stability as well as a related blue-green dyad. The newly established dyad is extended by a blue Bodipy to provide a useful triad, in which the blue excitation energy is transferred to the green fluorophore, followed by transfer to the red fluorophore whose emission is observed when spatial vicinity between the three dyes is given.
