Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 5-Bromo-4-methyl-thiazol-2-ylamine hydrobromide, is researched, Molecular C4H6Br2N2S, CAS is 79247-77-1, about Synthesis, Properties, and Solar Cell Performance of Poly(4-(p-alkoxystyryl)thiazole)s.Quality Control of 5-Bromo-4-methyl-thiazol-2-ylamine hydrobromide.
Polythiazoles (PvTzs) featuring conjugated styryl sidechains equipped with different solubilizing p-alkoxy-groups (-OR, R = n-octyl, n-dodecyl, 2-ethylhexyl, 2-hexyldecyl) is prepared by Negishi-coupling polycondensation. Soluble material with number-average mol. weights of up to Mn = 8.5 kDa (polydispersity (PDI) = 1.3, d.p. (DPn) ≈ 20) is obtained, with a head-to-tail content of the PvTzs of ≈77%, as estimated from comparison with reference polymers. The polymers exhibit optical absorption properties similar to their polythiophene analogs, while their electrochem. characterization shows a significant stabilization of their frontier orbital levels. Fluorescence measurements indicate that upon excitation of the electron rich alkoxystyryl side-chains charge transfer onto the more electron deficient polythiazole backbone occurs. This finding is corroborated by d. functional theory (DFT) calculations on oligomeric model systems, which also consistently reproduce the optical properties observed for the polymers. The potential of these materials for applications in organic electronics can be demonstrated by their use as donor materials in organic photovoltaic cells, which exhibit higher open circuit voltages (VOC, up to 0.86 V) than P3HT- or analogous polythiophene-based cells (VOC = 0.5-0.6 V).
After consulting a lot of data, we found that this compound(79247-77-1)Quality Control of 5-Bromo-4-methyl-thiazol-2-ylamine hydrobromide can be used in many types of reactions. And in most cases, this compound has more advantages.
