In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 3939-23-9, name is 3-Bromo-10H-phenothiazine, introducing its new discovery. Formula: C12H8BrNS
New banana shaped A?D?pi?D?A type organic dyes containing two anchoring groups for high performance dye-sensitized solar cells
Two new bent A?D?pi?D?A type organic dyes (MA-1 and MA-2) consisting of carbazole and phenothiazine moieties as electron donors with 2,1,3-benzothiadiazole as a pi-linker with two end-anchoring groups are designed, synthesized and tested in DSSCs. The photophysical and electrochemical properties of the dyes are investigated in detail. Incorporation of phenothiazine unit in MA-2 resulted in high HOMO level (0.62?V vs. NHE), with a red shift in absorption maxima and broadening of the absorption spectrum. Under standard global AM 1.5 solar conditions, the MA-2 sensitized solar cells exhibited a short circuit photocurrent density of 13.1?mA?cm?2, an open-circuit voltage of 0.73?V, a fill factor of 0.72, corresponding to an overall conversion efficiency of 6.87%. Such design and development of molecular dyes are useful for improving the overall efficiency of DSSCs.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C12H8BrNS, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about Formula: C12H8BrNS, in my other articles.
