Computed Properties of C12H10Cl2N2On May 30, 2000, Wu, Xufeng; Fraser, Cassandra L. published an article in Macromolecules. The article was 《Architectural Diversity via Metal Template-Assisted Polymer Synthesis: A Macroligand Chelation Approach to Linear and Star-Shaped Polymeric Ruthenium Tris(bipyridine) Complexes》. The article mentions the following:
Polymeric metal complexes were constructed by combining living polymerization techniques with coordination chem. These metal-centered linear and star-shaped materials combine the film-forming properties of polymers with optical and other features of metal complexes. A metal template approach offers a versatile alternative to the metallo-initiator method previously employed to generate Ru tris(bipyridine)-centered polystyrenes. Specifically, 4,4′-bis(chloromethyl)-2,2′-bipyridine and 4-chloromethyl-2,2′-bipyridine were utilized as initiators for both the bulk and solution polymerization of styrene using atom transfer radical polymerization (ATRP). Narrow dispersity polystyrenes with bipyridine (bpy) binding sites at the end (bpyPS) or center (bpyPS2) of the chains result. These bpyPSn macroligands were chelated to Ru precursor complexes, RuL2Cl2 (L = bpy, phen) or Ru(DMSO)4Cl2, to form complexes with one or three bpyPSn macroligands, resp. Linear polymers, [RuL2(bpyPSn)]2+, with Ru chromophores at the end or center of the chains, and Ru-centered star-shaped polymers, [Ru(bpyPSn)3]2+, with three and six arms were produced. In all cases, dehalogenation with AgPF6 was crucial for efficient macroligand chelation. The relative efficiency of these reactions was estimated by UV/vis spectroscopy. Mol. weight determination by GPC was coupled with in-line diode array UV/vis spectroscopy to confirm the presence of the Ru chromophores in the eluting polymer fractions. The convergent macroligand chelation approach to star-shaped polymeric metal complexes typically works best for polymers of low to moderate mol. weights (<∼65K), with higher mol. weights possible for systems with a single macroligand coordinated. Specific mol. weight thresholds encountered are determined by the number of macroligands, the position of the bpy on the polystyrene chain, and the total number of arms emanating from the metal core. In the part of experimental materials, we found many familiar compounds, such as 4,4'-Bis(chloromethyl)-2,2'-bipyridine(cas: 138219-98-4Computed Properties of C12H10Cl2N2)
4,4′-Bis(chloromethyl)-2,2′-bipyridine(cas: 138219-98-4) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. Computed Properties of C12H10Cl2N2 Pyridine has a conjugated system of six π electrons that are delocalized over the ring.
