Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. In an article, author is Dutta, Tanmoy, once mentioned the application of 91526-18-0, Recommanded Product: 91526-18-0, Name is 4-(Hydroxymethyl)-5-methyl-1,3-dioxol-2-one, molecular formula is C5H6O4, molecular weight is 130.0987, MDL number is MFCD12165896, category is dioxole.
Phenyleneethynylene-based conjugated copolymers using benzo[1,2-d:4,5-d’]bis[1,3]dioxole (BDO) in the repeating unit are reported. The electronic structure of the BDO unit imparts a localized HOMO topology while the LUMO is delocalized over the polymer backbone, so that the lowest optical absorption band of the polymer has considerable intramolecular charge transfer character. This contrasts with published donor-acceptor polymers with localized LUMO and delocalized HOMO. The very large Stokes shifts of the monomers, which are due to the small oscillator strength of the lowest optical transition, are largely retained in the polymers as a result of covalently constrained dihedral angles in the substituents (not the backbone), as predicted/explained by calculations.
Recommanded Product: 91526-18-0, By the way, if you are interested in learning more fun chemistry with your kids, get your hands into one chemistry set now, and start enjoying the best part of chemistry: experiments about 91526-18-0.
