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, 52409-22-0, name is Pd2(DBA)3, introducing its new discovery. category: catalyst-palladium
Effects of selenium substitution on optical, electrochemical, and photovoltaic properties of oxindole-based pi-conjugated polymers
Two oxindole based pi-conjugated polymers with same structures except the positions of selenium atoms in the main chains have been synthesized. The effects of heavy atom substitution on optical, electrochemical, and photovoltaic properties have been investigated. The polymer solar cell devices based on the new polymers as electron donors also have been studied. The oxindole based polymers showed intramolecular non-bonded interactions between divalent sulfur/selenium and carbonyl oxygen. The selenophene based polymers showed narrow optical band gaps. However, the introduction of selenophene led to the decline of optical absorption in both the monomer and the polymers compared with the thiophene based counterparts. The diminution of absorption in selenium containing polymers can have adverse effect on solar photon harvesting.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 52409-22-0, and how the biochemistry of the body works.category: catalyst-palladium
