dc.description.abstract | Two novel mer-Ru(II) heteroleptic complexes containing stongly donating tridendate ligands (dgpy and dgpz) were synthesised and optoelectronically characterised. These complexes exhibited quasi-reversible ligand- and metal-based redox events and panchromatic absorption with the lowest energy absorption maxima trailing up to 750 nm. These panchromatic dyes were found to be NIR emissive at λPL ~ 835 nm with associated excited-state lifetimes (τPL) of ~ 10 ns. The enhanced photophysical properties of these complexes compared to those of [Ru(tpy)2]2+ (tpy = 2,2′:6′,2′′-terpyridine; λabs < 575 nm, λPL ~ 629 nm and τPL ~ 0.25 ns) are due to the larger 3MLCT-3MC energy-gap as a combined effect of larger bite angle and strong σ-donation offered by the dgpy and dgpz ligands. | |
