Pouliot, Jean-Remi; Wakioka, Masayuki; Ozawa, Fumiyuki; Li, Yuning; Leclerc, Mario published the article 《Structural Analysis of Poly(3-hexylthiophene) Prepared via Direct Heteroarylation Polymerization》. Keywords: polyhexylthiophene heteroarylation polymerization.They researched the compound: trans-Di-μ-acetatobis[2-[bis(2-methylphenyl)phosphino]benzyl]dipalladium( cas:172418-32-5 ).Electric Literature of C46H46O4P2Pd2. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:172418-32-5) here.
This study reports the synthesis and characterization of poly(3-hexylthiophene) (P3HT) from a direct heteroarylation polymerization of two isomeric monomers, 2-bromo-3-hexylthiophene (monomer 1) and 2-bromo-4-hexylthiophene (monomer 2). Using the Herrmann-Beller catalyst along with P(o-NMe2Ph)3, the resulting polymers are obtained in excellent yields and exhibit a good number-average mol. weight (Mn of 33 and 16 kDa, resp.). Detailed 1H NMR analyses reveal less than 1% of homocouplings and no evidence of β-branching. Dehalogenation is identified as the main chain termination step and preferentially occurs on monomer 2. The melting temperature (237 °C) and hole mobility (up to 0.19 cm2 V-1.s-1) of the nearly defect-free P3HT obtained from this simple polymerization of monomer 1 are comparable, if not superior, to those obtained with com. available GRIM and Rieke samples.
This literature about this compound(172418-32-5)Electric Literature of C46H46O4P2Pd2has given us a lot of inspiration, and I hope that the research on this compound(trans-Di-μ-acetatobis[2-[bis(2-methylphenyl)phosphino]benzyl]dipalladium) can be further advanced. Maybe we can get more compounds in a similar way.
