  Porphyrin Synthesis in Surfactant Solution:  Multicomponent Assembly in Micelles

  摘要：

  A synthesis of meso-substituted porphyrins in anionic sodium dodecyl sulfate micelles has been developed. Polar, functionalized aromatic aldehydes condense reversibly with pyrrole in the micellar phase. Oxidation of the porphyrinogen then provides functionalized porphyrins in yields of 10-48%. Hydrophobic aldehydes condense irreversibly to give low yields at practical substrate concentrations. Synthesis in D2O solution results in per-beta-deuterated porphyrins. A two-phase model is used to rationalize the dependence of porphyrin yield on reactant and surfactant concentration. Micelles are viewed as potential wells which promote porphyrinogen assembly by binding products more tightly than reactants.

  A lithium ion battery includes a positive electrode, a negative electrode, and a microporous polymer separator soaked in an electrolyte solution. The microporous polymer separator is disposed between the positive electrode and the negative electrode. An ion exchange polymer material is any of i) incorporated as a binder in any of the positive electrode or the negative electrode, ii) deposited onto a surface of any of the positive electrode or the negative electrode, iii) incorporated into the microporous polymer separator, or iv) deposited onto a surface of the microporous polymer separator. Examples of methods for making the ion exchange polymer material for use in the lithium ion batteries are also disclosed herein.

  A membrane electrode assembly for fuel cells includes a proton conducting membrane having a first side and a second side. The membrane electrode assembly further includes an anode disposed over the first side of the proton conducting layer and a cathode catalyst layer disposed over the second side of the proton conducting layer. One or both of the anode catalyst layer and the cathode catalyst layer includes a first polymer which has cyclic polyether groups. An ink composition for forming a fuel cell catalyst layer is also provided.
