Published in 2020 at "Dyes and Pigments"

DOI: 10.1016/j.dyepig.2020.108277

Abstract: Abstract Three furan-based diketopyrrolopyrrole (DPP) chromophores have the same D−A−D structure and various tetraphenylethylene, pyrene and dibenzothiophene tails with intramolecular donor-acceptor spacers. Different π-extended chromophores show different intramolecular charge transfer properties. Furthermore, according to UV–Vis… read more here.
