Abstract: Abstract of thesis entitled DESIGN AND SYNTHESIS OF LUMINESCENT MONO- AND DINUCLEAR PLATINUM(II) ALKYNYL TERPYRIDINE COMPLEXES - FROM PHOTOPHYSICS TO AGGREGATION AND SELF-ASSEMBLY submitted by CHAN Hoi Yiu for the degree of Doctor of Philosophy at The University of Hong Kong in August 2006 A series of mononuclear alkynylplatinum(II) terpyridyl complexes, [Pt(trpy)({C{ C} C H )]PF, [Pt(trpy)({C{ C} C H CF -4)]PF, n 6 5 6 n 6 4 3 6 [Pt(trpy)({C{ C} C H CH -4)]PF, and [Pt( Bu trpy)(C{ C C{ C C H )]PF (n = n 6 4 3 6 3 6 5 6 2, 3), have been synthesized. The X-ray crystal structures of the two forms of [Pt(trpy)(C{ C C{ C C H )]PF, [Pt(trpy)(C{ C C{ C C{ C C H CH -4)]PF and 6 5 6 6 4 3 6 [Pt( Bu trpy)(C{ C C{ C C H )]PF have been determined. Dinuclear and 3 6 5 6 trinuclear alkynylplatinum(II) terpyridyl complexes, [1,4- {Pt(trpy)C{ C} C H ](OTf), [1,4-{Pt( Bu trpy)C{ C} C H ](OTf), [2,5- 2 6 4 2 3 2 6 4 2 {Pt(trpy)C{ C} C H S](OTf), [2,5-{Pt( Bu trpy)C{ C} C H S](OTf) and [1,3,5- 2 4 2 2 3 2 4 2 2 {Pt( Bu trpy)C{ C} C H ](OTf) have been successfully synthesized. The X-ray 3 3 6 3 3t crystal structure of [1,4-{Pt( Bu trpy)C{ C} C H ](OTf) has also been 3 2 6 4 2 determined. The luminescence properties of these complexes have been studied and their lowest-lying excited states in fluid solution and in the glass state were tentatively assigned as admixture of MLCT [dS (Pt)ĺ S *(trpy)] and LLCT [S (C{ C)ĺ S *(trpy)] origin, whereas the low-energy emissions in the solid state were attributed to triplet metal metal-to-ligand charge transfer ( MMLCT) phosphorescence, resulting from significant Pt---Pt interactions in the solid state. Besides, a series of luminescent platinum(II) terpyridyl alkynyl complexes with different counter anions, [Pt(trpy)(C{ C C{ C H)]X (X = OTf, PF, ClO, 6 4 BF, BPh ), [Pt(trpy)(C{ C C H )]X (X = OTf, PF, ClO, BF ) and 4 4 6 5 6 4 4 complexes with various substituents on the alkynyl and terpyridyl ligands, [Pt(trpy)(C{ CC H OCH-4)]OTf, [Pt(4'-CH O trpy)(C{ C C H )]OTf, 6 4 3 3 6 5 [Pt( Bu trpy)(C{ C C{ CH)]OTf, [Pt(trpy)(C{ CC H {CH NMe }-4)](OTf), 3 6 4 2 3 2 [Pt(trpy)(C{ C C{ C CH NMe )](OTf) and [Pt(trpy)(C{ C C{ C CH OH)]OTf 2 3 2 2 have been synthesized and their photophysical properties have been stuided. The X-ray crystal structure of [Pt(trpy)(C{ C C H )]ClO and 6 5 4 [Pt( Bu trpy)(C{ C C{ C H)]OTf have been determined. The solid-state absorption and emission spectra showed low-energy bands, which were assigned as derived from MMLCT origin. Solvent-induced aggregation studies of these complexes in solution showed that the color of the aggregates could be very different for different counter-ions, indicating that counter-ions played an important role in governing the degree of aggregation and the extent of interactions within these aggregates. Addition of various anions to solutions of [Pt(trpy)(C{ C C{ C H)]X (X = OTf, PF ) produced anion-induced color 6changes upon solvent-induced aggregation, showing that these complexes might serve as potential colorimetric anion probes. The effect of temperature on the aggregation properties of the complexes has also been explored. New low-energy absorption and emission bands were found upon a reduction of temperature, attributable to the formation o
