Pcbm solubility

Spletadditive has a higher boiling point than the main solvent and provides better solubility for one of the components. In the case of 1,8-octanedithiol, 1,8-diiodooctane and 1-chloronaphthalene the solubility of PCBM is larger than a donor-polymer such as poly(3-hexylthiophene) (P3HT) [4] and this results in the formation of large domains of PCBM. SpletTherefore, the solubility of a PCBM 0.76 1.15 1.68 2.19 new fullerene derivative in a given solvent cannot be predicted with high accuracy but has to be measured experimentally instead. The common assumption that the solubility of fullerene derivatives can be fully controlled by simply appending larger or smaller, branched or linear ...
