Synthesis and characterization of poly{2-[3-(1H-pyrrol-2-yl)phenyl]-1H-pyrrole} and its copolymer with EDOT
摘要:
A pyrrole-functionalized monomer 2-[3-(1H-pyrrol-2-yl)phenyl]-1H-pyrrole (PyPhPy) was synthesized. The structure of monomer was investigated by Nuclear Magnetic Resonance (H-1 NMR) and Fourier Transform Infrared (FTIR) spectroscopy. The chemical polymerization of PyPhPy (CPyPhPy) was realized using FeCl3 as the oxidant. The electrochemical oxidative polymerization of polymer P(PyPhPy) and its copolymer with 3,4-ethylenedioxythiophene poly(2-[3-(1H-pyrrol-2-yl)phenyl]-1H-pyrrole-co-3,4-ethylenedioxythiophene) [P(PyPhPy-co-EDOT)] were achieved via potentiodynamic method by using NaClO4/LiClO4 as the supporting electrolyte in CH3CN. Characterizations of the resulting polymers were performed by cyclic voltammetry (CV), FTIR, scanning electron microscopy (SEM), UV-Visible spectrophotometry (UV-Vis) and thermogravimetry analyses (TGA). Electrical conductivity of CPyPhPy, P(PyPhPy), and P(PyPhPyco-EDOT) were measured by four-probe technique.

Provided herein are unsymmetrical bis(azolium) salts, unsymmetrical CCC-NHC metal complexes, and methods of forming the same. The unsymmetrical bis(azolium) salts include a central aryl ring that is substituted with two heterocyclic rings in an ortho, meta, or para fashion. The unsymmetrical CCC-NHC metal complexes include metalated unsymmetrical bis(azolium) salts. The method of forming the unsymmetrical CCC-NHC metal complexes includes reacting a dihalogenated benzene with a first azole to form a mono(azole)benzene, reacting the mono(azole)benzene with a second azole to form an unsymmetrical bis(azole)benzene, alkylating the unsymmetrical bis(azole)benzene to form an unsymmetrical bis(azolium) salt, and metalating the unsymmetrical bis(azolium) salt to form the unsymmetrical CCC-NHC metal complex. Also provided are a bis-ligated CCC-NHC metal complex and an unsymmetrical bimetallic complex.

bonding donor groups are found in both compounds. The basic building block for 9 a, benzene dipyrrole 8 a, also displays a higher affinity for anions than the building block for 1, dimethyldipyrromethane 16. Structuralstudies, carried out by single-crystal X-ray diffraction analyses, are consistent with the solution-phase results and reveal that 9 a is able to stabilize complexes with chloride and nitrate

functional skeletons, binding sites, and topological structures could be facilely achieved through the rational design and replacement of reaction modules (furan and thiophene), functional modules (substituted benzene, biphenyl, and naphthalene), and linking modules (methylene). These biphen[n]arenes were characterized by NMR, HRMS, and X-ray crystalline diffraction, complemented by DFT calculations. Their
