In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis, Properties, and Solar Cell Performance of Poly(4-(p-alkoxystyryl)thiazole)s, published in 2018, which mentions a compound: 79247-77-1, mainly applied to solar cell polyalkoxystyrylthiazole, HPLC of Formula: 79247-77-1.
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).
Although many compounds look similar to this compound(79247-77-1)HPLC of Formula: 79247-77-1, numerous studies have shown that this compound(SMILES:NC1=NC(C)=C(Br)S1.[H]Br), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
