WebJan 1, 2011 · Table 4 presents comprehensive photophysical data of 2T–7T (di-n-butyl), including singlet oxygen quantum yields (ϕ Δ) in benzene.Considering the absorption and emission spectra, there is a relatively small effect of solvent on these maxima. In the fluorescence excitation spectra, there is a considerable red shift, ∼1600 cm −1, in the … WebThiophene side-chain monomers [20]. Eventually, the conjugated thiophene monomer is built into the polymer via the aldehyde groups. The polymers exhibit a good thermal stability and film-forming ability. The absorption spectra show a broader absorption band from 300 to 580 nm in comparison to a PPV type without conjugated thiophene side chains.
