The ability to tailor synthetic porphyrin, chlorin and bacteriochlorin mols. holds promise for diverse studies in artificial photosynthesis. Toward this goal, the synthesis and photophys. characterization of five tetrapyrrole compounds is described. Each compound bears a surface attachment group. One set contains three meso-substituted porphyrins that differ only in the nature of a surface-binding tether-isophthalic acid, ethynylisophthalic acid or cyanoacrylic acid. The other set includes a porphyrin, chlorin and bacteriochlorin each of which bears an ethynylisophthalic acid tether. The ester derivative of each compound was prepared for solution photophys. characterization studies. The photophys. studies include determination (in toluene or acetonitrile) of the electronic absorption and fluorescence spectra, fluorescence yield and lifetime of the lowest excited singlet state. The excited-state lifetimes range from 1 to 5.6 ns for the five compounds The radiative rate constant for the excited-state decay was estimated from the photophys. data (fluorescence yield and excited-state lifetime) and from Strickler-Berg anal. of the absorption and fluorescence spectra. The synthesis and characterization of the tetrapyrrole compounds underpin their use as sensitizers in mol.-based solar cells. In the experiment, the researchers used many compounds, for example, Dimethyl 5-ethynylisophthalate (cas: 313648-56-5Recommanded Product: Dimethyl 5-ethynylisophthalate).
Dimethyl 5-ethynylisophthalate (cas: 313648-56-5) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Recommanded Product: Dimethyl 5-ethynylisophthalate
