In heterogeneous catalysis, the catalyst is in a different phase from the reactants. SDS of cas: 52409-22-0, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 52409-22-0, name is Pd2(DBA)3. In an article，Which mentioned a new discovery about 52409-22-0
Cyano substituted (Z)-(thienylmethylene)-2-indolone as a new building block for near-IR absorbing polymers
A new electron withdrawing monomer, cyano substituted (Z)-(thienylmethylene)-2-indolone (TEI(CN)) has been synthesized and polymerized with different donors to give three alternating donor/acceptor conjugated polymers. The cyano substituted polymers showed significantly reduced LUMO energy levels and small optical bandgaps compared with un-substituted polymer. The optical absorptions of new polymers mainly appeared in NIR range, peaked at 700?800 nm. With strong electron donor EDOT, the polymer, PTEI(CN)-EDOT showed most of its absorption in NIR region (>700 nm). The inverted bulk hetero-junction polymer solar cells based on two of the new polymers were fabricated and tested.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 52409-22-0, help many people in the next few years.SDS of cas: 52409-22-0
