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

Abstract: Several cyclometalated Pt(II) isocyanide complexes containing C-deprotonated C DEGREESN DEGREESC ligands (C DEGREESN DEGREESC = 2,6-diphenylpyridine derivatives) were synthesized. These complexes display orange-red emissions with max at 582-619 nm and quantum yields of up to 26% in CH2Cl2 at room temperature. The incorporation of carbazole/fluorene/thiophene unit(s) to C DEGREESN DEGREESC ligands leads to minimized structural distortion of complexes in their excited states and thereby suppresses non-radiative decay pathways. The high thermal stability (Td >300 C) renders these complexes good candidates as phosphorescent dopants in organic light-emitting diodes (OLEDs). Red-emitting OLEDs with CIE coordinates of (0.650.01, 0.350.01) were fabricated by vacuum deposition, showing a maximum external efficiency of 12%. In addition, well-defined nano/microstructures were obtained from self-assembly of these complexes driven by π∙∙∙π, C-H∙∙∙π and C-H∙∙∙H-C interactions as observed in the crystal structures. Two series of organopalladium(II) alkynyl complexes containing a terpy (terpy = 2,2':6',2''-terpyridine) or C DEGREESN DEGREESC pincer carbene ligand (C DEGREESN DEGREESC = 2,6-bis(1-butylimidazol-2-ylidenyl)pyridine) were prepared. These complexes are non-emissive in solution at room temperature except that the one containing both C DEGREESN DEGREESC and pyrenylacetylide ligands shows phosphorescence (Φ = 0.3%) originating from intraligand state of the acetylide ligand. This could be attributed to the strong -donating N-heterocyclic carbene (NHC) in the pincer ligand that strongly destabilizes d-d state, the population of which provides an efficient non-radiative decay channel. To make comparison between Pd(II) and Pt(II) complexes with the two ligand systems, Pt(II) C DEGREESN DEGREESC alkynyl complexes were also prepared. They are emissive in solution and some display excimer emissions at high concentration (〖10〗 DEGREES(-4)-〖10〗 DEGREES(-3) mol 〖10dm〗 DEGREES(-3)). The X-ray crystal structures of [Pd(L)(CCPh)](〖PF〗_6) (L = terpy and C DEGREESN DEGREESC) revealed one-dimensional chain stacking of complex cations with alternating Pd(II)∙∙∙Pd(II) contacts of about 3.29-3.35 A and π-π interactions of about 3.4 A . Well-defined submicron/nanostructures were obtained from self-assembly of Pd(II) and Pt(II) alkynyl complexes driven by π-π interactions between aromatic moieties and/or metal∙∙∙metal interactions. DFT calculations on the optimized structures of [M(L)(CCPh)]+ (M = Pd(II) and Pt(II)) revealed the existence of metal∙∙∙metal closed-shell interactions. In addition, the complex containing the C DEGREESN DEGREESC ligand exhibits slightly enhanced metal∙∙∙metal interactions and larger "bonding" energy upon dimerization. Furthermore, spin-orbit coupling between singlet and triplet excited states is more effective which promotes rapid intersystem crossing. A new class of cyclometalated Au(III) complexes containing C-deprotonated C DEGREESN ligands (C DEGREESN = 2-phenylpyridine and its derivatives) and cis-chelating bis-NHC ligands was synthesized. These are the first examples of Au(III) complexes supported by cis-chelating bis-NHC ligands. They display emissions in solution under degassed condition at room temperature with &
