Two new dibenzofulvene functionalized rhenium chromophore of the form fac-[Re (bpy)(CO) 3 (L)] PF6 (bpy= 2, 2′-bipyridine) are reported, where L is a pyridine functionalized in para or meta position with a dibenzofulvene moiety. Results show interesting features of increased delocalization of the fulvene ligand into the rhenium core for one of the complexes. Neither complex emits, suggesting energy transfer toward the lowest energy ...
