Stereoisomer resolution of 2-ethylhexyl-substituted cyclopentadithiophene and its effect on optical properties of donor–acceptor–donor conjugated molecules
Mono-formylated cyclopentadithiophene bearing two 2-ethylhexyl chains (CPDT-CHO) was successfully resolved into three stereoisomer fractions, assigned as (<i>R</i>,<i>S</i>), (<i>S</i>,<i>R</i>), and a mixture of (<i>R</i>,<i>R</i>) and (<i>S</i>,<i>S</i>). The distinct stereochemistry influenced the absorption spectra of the corresponding CPDT-acceptor-CPDT conjugated molecules.
