Photocatalytic fixation of carbon dioxide has been achieved by utilizing poly(3-alkylthiophene) as a new class of photocatalyst.Irradiation of visible light onto a poly(3-alkylthiophene) film immersed in ethanol solution containing butylphenol under a CO2 atmosphere resulted in formation of butylsalicyclic acid.The amount of butylsalicyclic acid formed increased with irradiation time.The mechanism of this novel photocatalytic CO2 fixation reaction was discussed by measuring the quenching effects of carbon dioxide and phenol on the photoluminescence of poly(3-alkylthiophene) and the electrochemical oxidation and reduction potentials of poly(3-alkylthiophene), CO2, phenol and phenolate anion.By using lithium phenolate as a starting substrate, the reaction rate was enhanced markedly.

A modular ligand macrocycle is composed from two phenolic groups linked to a cyclohexane bridge through an amide bond and an imine bond. The stability of the asymmetric linkers to metathesis permits a macrocyclic platform to be assembled from the condensation of two different phenolic groups in a single-step, high yield, reaction. The primary coordination sphere may be tuned with functional groups on one phenolic group. The other phenolic group may be modified with a scaffold possessing a proton transfer group. In this way, control over the secondary coordination sphere of the macrocycle is achieved. Manganese complexes of the amido-imine linked macrocycle catalytically epoxidizes 1,2-dihydronapthalene using sodium hypochlorite as the oxidant. The amido-imine macrocycles represent a new metal active site capable of supporting high oxidation states and attendant atom transfer chemistry while at the same time permitting control over the primary and secondary sphere of the metal center.
