Available in PDF, EPUB and Kindle. Book excerpt: Rhenium complexes play a significant role in nuclear medicine. Rhenium has been widely used as a surrogate of technetium for a long time, and the promising physical features of 186Re and 188Re, make 186/188Re-complexes promising candidates as therapeutic radiopharmaceuticals.Similarly, the interesting photoactive and photoluminescence properties of non-radioactive Re-complexes make them excellent catalysts, luminescent materials and imaging sensors.Thus, in this work, our goal was to (i) develop, using a click chemistry strategy, multidentate ligands for the stabilization of different rhenium cores [Re(CO)3]+ and [ReO]3+ (M = Re or 188Re) as well as the analogous 99mTc-cores in some examples, (ii) assess the potential of the rhenium(technetium) complexes as imaging (natRe or 99mTc) or therapeutic (188Re) agents. To do so, two rhenium(technetium) specific-chelating systems were used: a semi-rigid tripodal system in the second chapter and a pyta moiety in the third chapter, these two chelators being developed previously in our group. Thus, based on a N2O tridentate click ligand, two different studies were carried out in chapter II. In the first one, two synthetic pathways to a range of potentially N3O tetradentate ligands, designed to coordinate rhenium cores as well as their coordination behaviors towards different rhenium cores (oxidation states +I and +V), were investigated. The first radiolabeling results combined with the recent work reported by Dugave and co-workers indicated that this ligand could be a promising 99mTc-chelator for nuclear imaging applications. As perspectives to this work, the extension of the radiolabelling work using the [188ReVO]3+ core should be performed, and the in vitro stability should be tested under physiological conditions in human plasma and by cysteine exchange experiments. The second study was focused on the development of novel hypoxia-selective 99mTc radiopharmaceuticals. Our semi-rigid tripodal click framework was decorated with an appended nitro group (either a nitrobenzyl group or a metronidazole (Mtz) unit). Different positions were considered and at least only two metronidazole (Mtz)-containing ligands and one nitro group-containing ligand as well as their corresponding tricarbonyl rhenium(I) complexes were obtained and characterized, in particular by electrochemistry. The reduction potentials of NO2 group in complexes [Re(CO)3Cl(L2)] and [Re(CO)3(L6)] were similar to those of reported hypoxic imaging agents, prompting us to further investigate other properties of these complexes. Chapter III was focused on the study of AIE (aggregation-induced emission) effect in tricarbonyl Re(I) complexes, the association of this effect with the intrinsic properties of Re(I) complexes being expected to lead to very attractive compounds. To do that, we combined an organic fluorophore (PBO) which exhibits excellent stability and optical properties, with a tricarbonylrhenium(I) complex based on a pyta unit (either a 2-pyridyl-1,2,3-triazole or a 2-pyridyl-1,2,4-triazole ligands). Four compounds were studied. The X-Ray structures revealed spectacular discrepancies between the two first triazole-based complexes ReL8 and ReL9. Moreover, this study being a novel orientation in our group, this work is a great starting point for further investigations. Various organic dyes and/or structural modifications of the organic moiety will soon be considered in order to develop highly emissive rhenium(I) luminescent probes.

Abstract: Abstract of thesis entitled SYNTHESIS, OPTICAL AND LUMINESCENCE STUDIES OF RHENIUM(I) DIIMINE ALKYNYL COMPLEXES AND THEIR UTILIZATION AS BUILDING BLOCKS FOR THE ASSEMBLY OF MULTINUCLEAR AND MIXED-METAL COMPLEXES submitted by LAM Chan Fung for the degree of Doctor of Philosophy at The University of Hong Kong in July 2005 A series of mononuclear rhenium(I) diimine complexes with hyperbranched or functional alkynyl ligands, [C H -1,3-(HC C C H C C) -5-{Re(CO) (N N)(C C 6 3 6 4 2 3 t C H C C)}] (N N = bpy, Bu bpy) and [Re(CO) (N N)(C C C C R)] (R = C H I-p, 6 4 2 3 6 4 C H C C SiMe -p, CHC C H-p, C H OSiMe Bu-p, CHOH-p) have been 6 4 3 6 4 6 4 2 6 4 synthesized. The X-ray crystal structures of [CH-1,3-(HCCCHCC)-5-{Re(CO)(Bubpy)(CCCHCC)}] and 63 64 2 32 64 [Re(CO)(Bubpy)(CCCCCHCCH-p)] have been presented. By employing 32 64 [Re(CO) (N N)(C C C C C H I-p)] as a precursor, a series of dinuclear rhenium(I) 3 6 4 alkynyl complexes with extended conjugation, [Re(CO) (N N)(C CC C C H C C 3 6 4 t (C H ) C C C H C CC C)Re(CO) (N N)] [n = 0, 1; N N = Bu bpy, (CF ) bpy], 6 4 n 6 4 3 2 3 2 have been prepared. Additionally, a series of symmetrical and unsymmetrical trinuclear rhenium(I) alkynyl complexes, [C H -1,3,5-{Re(CO) (N N)(C C C C 6 3 3 t t C H C C)} ] [N N = Bu bpy, (CF ) bpy] and [C H -1,3-{Re(CO) (Bu bpy)(C C 6 4 3 2 3 2 6 3 3 2 C C C H C C C H C C)} -5-{Re(CO) ( Bu bpy)(C C C H C C)}], have also 6 4 6 4 2 3 2 6 4 been synthesized. The lowest-lying excited states of these complexes were 3 3 tentatively assigned as admixture of MLCT[d (Re) *(N N)], LLCT[ (C C R) 3 *(N N)] and IL[ (C C R) *(C C R)] origin. Besides, a series of luminescent heterometallic rhenium(I) palladium(II) t complexes, trans-[Pd(PEt ) Cl{(C C Ar C C)Re(CO) (N N)}] (N N = bpy, Bu bpy; 3 2 3 2 Ar = C H S, C H ) and trans-[Pd(PEt ) {(C C C H C C)Re(CO) ( Bu bpy)} ], have 4 2 6 4 3 2 6 4 3 2 2 been synthesized. The X-ray crystal structures of t trans-[Pd(PEt)Cl{(CCCHCC)Re(CO)(N N)}] (N N = bpy, Bu bpy) have been 32 64 3 2 determined. Their emission was attributed to MLCT[d (Re) *(N N)] 3 phosphorescence mixed with LLCT[ (C C R) *(N N)] character. A lower emission energy for the hetero-bimetallic complex was observed upon coordination of the electron-rich palladium(II) moiety into the rhenium(I) alkynyl system. However, replacement of the remaining chloro group on the palladium centre with an additional rhenium(I) alkynyl moiety resulted in a higher energy emission for the hetero-trimetallic complex. A series of luminescent heterometallic rhenium(I) platinum(II) phosphine complexes, [{Re(CO)(NN)(CCCHCC)}Pt(PP)] [PP = dppe, depe, 3 6 4 2 t cis-(PEt), trans-(PEt ); N N = Bu bpy, (CF ) bpy], have been synthesized. The 32 3 2 2 3 2 X-ray crystal structure of [{Re(CO){(CF)bpy}(C C CH C C)}Pt(dppe)] has 3 3 2 6 4 2 been determined. The emission was ascribed as derived from states of a [d (Re) 3 3 *(N N)] MLCT origin that mixed with LLCT[ (C C R) *(N N)] character; or alternatively, as an excited state of a [ {C C C H C C Pt(P P)} *(N N)] 6 4 metalloligand-to-ligand charge transfer character. Another new class of luminescent heterometallic rhenium(I)platinum(II) polypyridine alkynyl complexes, t [Re
