Experimental Section
- Chemicals Pyrrole, substituted benzaldehydes (p-anisaldehyde, p-nitrobenzaldehyde, 2,6-dichlorobenzaldehyde and benzaldehyde), triethylamine (TEA), p-terphenyl (TP) and ferrocene (Fc) were purchased from Sigma-Aldrich. Tetraphenylporphyrin (TPP) was purchased from Frontier Scientific. Acetonitrile (MeCN), dichloromethane (DCM), 1,4-dioxane, and other organic solvents used were spectroscopic grade. These solvents were distilled from appropriate drying agents under argon just prior to use. Water, Milli-Q grade, and argon of high purity were used.
- Instruments
Cyclic voltammetry (CV) measurements were carried out with a TEQ 03 potentiostat. For voltammetry in non-aqueous or organic solvent media (DCM or AcCN) a three-electrode system was used, consisting of two platinum electrodes, and either a working glassy carbon electrode; the supporting electrolyte (SE) was N(Bu)4PF6 (0.1M). De-aeration of all solutions was accomplished by passing a stream of high-purity argon through the solution for 10 min and maintaining a blanket of inert gas over the solution while making the measurements. The inert gas was saturated with the appropriate solvent before entering the cell to minimize the evaporation of solvent from the cell. The potential was measured …show more content…
QUADERA software was used for data acquisition and control. The setup involves placing the gas analyzer capillary at one of the outputs of a booth-necked quartz flask containing solution of the metallocorrole. The output was free to perform water additions, using a micro syringe, through a septum closure. The gas detector was connected to the photocatalytic system as shown in Figure
