Synthetic Route of 224311-51-7, An article , which mentions 224311-51-7, molecular formula is C20H27P. The compound – 2-(Di-tert-Butylphosphino)biphenyl played an important role in people’s production and life.
Narrow bandgap and hyperbranched polymers (h-PTDPP) are synthesized by directly arylation polymerization (DAP) of 2-bromo-thiophene-flanked diketopyrrolopyrrole (Br-TDPP) as the monomer. Their optical properties as well as chemical structures are studied. The detailed optimization of DAP conditions from catalyst, temperature, solvent, ligand to additive not only leads to high molecular weight h-PTDPP, but also provides some insight to minimize structural defects in DAP when brominated TDPP is involved as a monomer. The increase in the degree of branching results in lower charge-carrier mobilities in organic field-effect transistors involving h-PTDPP-3 as the semiconducting channel.
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 224311-51-7, help many people in the next few years., Synthetic Route of 224311-51-7
