Product Details of 92-71-7. 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: 2,5-Diphenyloxazole, is researched, Molecular C15H11NO, CAS is 92-71-7, about Attempting to prepare a plastic scintillator from a biobased polymer. Author is Hamel, Matthieu; Lebouteiller, Guillaume.
A new plastic scintillator was prepared from a renewable polymer source. It is composed of the mighty 2,5-diphenyloxazole and 1,4-bis(2-methylstyryl)benzene mols. (PPO and bis-MSB), acting as primary and secondary fluorophores, resp., together dissolved in a polylactic acid matrix-PLA. This polymer is indeed considered as the biomass-based equivalent of petroleum-derived plastics in terms of mech. and optical properties. Subsequent to the bis-MSB emission, the emission wavelength is centered around 424 nm and the fluorescence decay time is in the nanosecond range. The material was fully characterized, and its scintillation performances were compared to a com. PVT-based plastic scintillator: EJ-200. Like polystyrene- or polyvinyltoluene-based scintillators, the material displayed a good response linearity with the energy of the incident gamma-ray. However, the observed scintillation yield was rather modest, with a reported 500 ph/MeV value when excited with a gamma-ray-emitting 60Co source. This preliminary test could pave the way to new and renewable polymers for unexpected applications such as nuclear physics.
As far as I know, this compound(92-71-7)Product Details of 92-71-7 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
