Wang, Ping; Zhang, Baozhong published their research in RSC Advances in 2021. The article was titled 《Sustainable aromatic polyesters with 1,5-disubstituted indole units》.Recommanded Product: 3-Bromopropan-1-ol The article contains the following contents:
This work aims to unravel the impact of disubstitution patterns on the phys. properties and processing characteristics of indole-based aromatic polyesters. A series of hydroxyl-carboxylate (AB-type) monomers with 1,5-disubstituted indole and 3-6 methylene units was conveniently synthesized and used in bulk polycondensation to yield the corresponding polyesters with decent mol. weight These new monomers and polyesters showed enhanced thermal stability compared to the previously reported monomers and polyesters with a 1,3-disubstituted indole structure. According to DSC results, these polyesters showed tunable glass transition temperatures (Tg ∼57-80°C), depending on the length of the aliphatic methylene units. DSC and WAXD measurements revealed that these polymers did not crystallize from melt, but the ones with 3 or 5 methylene units per repeating unit crystallized from solution Finally, we demonstrated that the new polyesters with 1,5-disubstituted indole units could be crosslinked using sustainable aromatic aldehyde, which could further enhance their thermal properties. After reading the article, we found that the author used 3-Bromopropan-1-ol(cas: 627-18-9Recommanded Product: 3-Bromopropan-1-ol)
3-Bromopropan-1-ol(cas: 627-18-9) was used in the synthesis of fluorescent halide-sensitive quinolinium dyes and molten salt-polymers. Furthermore, it was used in the synthesis of chiral, quaternary prolines via cyclization of quaternary amino acids.Recommanded Product: 3-Bromopropan-1-ol
