This paper presents the synthesis of several new C60 dicarboxylate esters. Blends with poly[2-methoxy-5-(2′-ethylhexoxy)-1,4-phenylene vinylene] were fabricated into polymer solar cells and the photovoltaic properties were tested. Effects of the substitution group attached to C60 core on the photovoltaic properties were studied. Energy conversion efficiency increased at 1st, and then decreased with increasing size of substitution group. Also group polarity plays an important role in the performance of polymer photovoltaic devices. In the experiment, the researchers used many compounds, for example, malonic acid dibutyl ester (cas: 1190-39-2Recommanded Product: malonic acid dibutyl ester).
malonic acid dibutyl ester (cas: 1190-39-2) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Recommanded Product: malonic acid dibutyl ester
