Rapid intramolecular energy transfer occurs from a free-base porphyrin to an attached osmium(II) bis(2,2':6',2' '-terpyridine) complex, most likely by way of the Förster dipole-dipole mechanism. The initially formed metal-to-ligand, charge-transfer

The synthesis is described for a series of five molecular dyads comprising pyrene-based terminals covalently linked through a 1,3-disubstituted phenylene spacer. The extent of through-space communication between the pyrene units is modulated by steri

The synthesis of a molecular dyad comprising two pyrene-based terminals covalently linked via a Hantzsch 1,4-dihydropyridine is described. The dyad is sufficiently flexible to allow the end groups to approach each other in fluid solution, as is evide

A complete photophysical study has been carried out on an octahedral ruthenium(II) complex, incorporating two 4′-phenylethynyl-2,2′:6′,2″-terpyridine ligands. Weak emission is observed from the complex in fluid solution at room temperature, b

A molecular triad has been synthesized comprising two free-base porphyrin terminals linked to a central ruthenium(II) bis(2,2':6',2''-terpyridine) subunit via meso-phenylene groups. Illumination into the ruthenium(II) complex is accompanied by rapid

The synthesis of a series of crown ether ligands (C4–C6) based upon the 2,2′-biphenyl unit is described. In the series, the length of the polyether chain connecting the two oxygen atoms increases progressively. These polyethers are moderately flu

The photophysical properties of osmium(II) bis(2,2‘:6‘,2‘ ‘-terpyridine) have been recorded over a wide temperature range. An emission band is observed and attributed to radiative decay of the lowest-energy metal-to-ligand, charge-transfer (M

Photophysical properties have been recorded for a ruthenium(II) bis(2,2':6',2' '-terpyridine) complex bearing a single ethynylene substituent. The target compound is weakly emissive in fluid solution at room temperature, but both the emission yield a

The binding behavior between a rigid, π-accepting aromatic polycycle (ADIQ.2PF 6 ) and an electron-donating crown ether (CE(10)) is reported in acetonitrile solution. In CH 3 CN at low concentration of crown ether, the binding data are consistent wi
