Selection of the combination of metal, ligand set, and spacer groups that are most appropriate to form a coordination complex with a desired function are of paramount importance in supramolecular chemistry. In particular, the establishment of reproducible methods to accomplish controlled selforganization of molecules to form polymers and homo-or heterometallic coordination aggregates is an important field of research.[1] Although important advances have already been made, few metallopolymers, which are one of the most exciting classes of functional materials, are water soluble. An important example of a water-soluble polymer is the polyferrocenylsilane-b-polyaminomethacrylate copolymer described by Manners and co-workers, [2] as part of their ongoing study on metallocene-based polymers.[3] Recent examples also include the water-soluble metallopolymer obtained by reaction of bipyridyl-appended poly(p-phenyleneethynylene) (PPEs) with metal ions in organic and aqueous solution. [4] Other examples of ligands that afford coordination polymers with various topologies and applications are ferrocenyl groups bearing bipyridine (bpy) [5] or carboxylate moieties.[6]A recent example of a non-water-soluble multimetallic polymer is [Sm(, in which the CN ligands bridge the samarium and ruthenium metal centers.[7]The first air-stable water-soluble multimetallic polymer that includes mixed P,N ligands as metal-coordinating spacers has been recently reported by us.[8] This heterobimetallic complex is based on two metal-containing moieties, [CpRu]À , and is bridged by the cagelike water-soluble monodentate phosphine 1,3,5-triaza-7-phosphaadamantane (pta) in an unprecedented P,N coordination mode. More recently, the synthesis of silver coordination polymers containing pta bridging molecules in a tridentate P,N,N' coordination mode [9] has been reported and several examples of pta N coordination have been presented.[10] Therefore the pta molecule could be an excellent ligand from which to obtain water-soluble Ru-Au polymers which could have interesting and useful properties for a variety of applications such as magnetism, [11] nonlinear optics, [12] electrocatalysis, [13] photocatalysis, [14] photovoltaic, [15] template formation of ordered networks, [16] advanced electrode materials, [17] and conjugated coordination polymers.[18]Herein, we describe the first water-soluble, air-stable heterobimetallic polymeric structure based on two metalcontaining moieties [CpRuCNRuCp] + and [Au(CN) 4 ] À , bridged by pta in the P,N coordination mode. Interestingly, this complex display gel-like properties [19] in water, specifically a thermally controlled volume transition. To the best of our knowledge, this is the first example of an coordination polymer network that is sensitive to its environment. The physical and chemical properties of this complex make it a promising material for industrial and biological applications, for example, smart catalysis, drug delivery, or chemical sensing.The first strategy we attempted to obtain a water soluble ...

“…They have highly desirable properties including microsecond lifetimes in solution, intense visible absorption and phosphorescence emission, good redox chemistry and high stability [14,15]. The PV devices using Re(I) complexes as electron acceptors have been demonstrated [10]. One of the most promising applications of these devices is the conversion of solar radiation into chemical energy [8].…”

“…Most efforts made in the past decade focused on conjugated polymers [3][4][5][6][7] and fullerenes [7][8][9]. Little attention has been devoted to organic metal complexes [9][10][11][12][13]. Carbonyl bipyridine Re(I) complexes and their derivatives, such as Re-Phen exhibit characteristic long-lived metal-to-ligand charge transfer (MLCT) excited states [14].…”
