Application of 75732-01-3. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Mesitylcopper(I), is researched, Molecular C9H11Cu, CAS is 75732-01-3, about Conjugated alternating copolymers with 4,4′-dimesitylboryl-2,2′-bithiophene as a building block.

The functionalization of polythiophene with dimesitylborane π-acceptor groups has a strong effect on the conjugated polymer backbone, resulting in interesting optical and electronic properties. To investigate the interplay between the electron-deficient organoborane substituents and the conjugated polymer main chain, a series of alternating copolymers was prepared Several aromatic building blocks that are commonly used in organic semiconductors, i.e. fluorene, carbazole, and triphenylamine, were chosen as comonomers for combination with 4,4′-diboryl-2,2′-bithiophene units. First, the trimethylsilyl-substituted copolymers PFT-Si, PCT-Si, and PTT-Si were prepared via standard Suzuki coupling reaction of 5,5′-diiodo-4,4′-bis(trimethylsilyl)-2,2′-bithiophene and the resp. pinacolborane-functionalized aromatic comonomer. Subsequent post-polymerization modification reactions, which involved treatment with BBr3 and then mesitylcopper, led to three borylated copolymers, PFT-B, PCT-B, and PTT-B. The ds.p. (DPn) and the polydispersities are consistent with those of the silylated precursor polymers. The photophys. and electrochem. properties of these new polymers have been studied in detail.
This literature about this compound(75732-01-3)Application of 75732-01-3has given us a lot of inspiration, and I hope that the research on this compound(Mesitylcopper(I)) can be further advanced. Maybe we can get more compounds in a similar way.
