“…The synthesis route toward TPA-2T-DCV-Me (Figure ) used our approach developed recently for the synthesis of star-shaped , and linear ,, oligomers and is based on the preparation of precursors with dioxane or dioxolane protective groups followed by a deprotection reaction and Knœvenagel condensation with malononitrile. The extension of this approach presented herein to the synthesis of unsymmetrical molecules such as TPA-2T-DCV-Me proves a high universality of the method as compared to an alternative synthesis approach based on Vilsmeier–Haack–Arnold acylation followed by Knœvenagel condensation as reported recently by Bakiev et al…”

“…Stokes shifts, which are the differences between the wavelengths of emission and absorption maxima, indicate the amount of consumed energy in the nonradiative process [71] and the geometry change from the ground state to the excited state [28]. As illustrated in Table S3, with increasing polarity of the solvent, the Stokes shift becomes larger for the same compound.…”

“…While admixture of CT configurations would red-shift the excitation energies, overlapping electron-hole configurations predominantly feed the oscillator strength, hence enabling large absorption cross-sections in the visible and solar light harvesting. The synthesis of the two dyes, their electrochemical and time-resolved Please do not adjust margins Please do not adjust margins photoluminescence (PL) characterization along with OSC device fabrication and testing have been reported elsewhere (8)(9)(10).…”
