DOI: 10.1002/adma.201707170
Abstract: Besides broadening of the absorption spectrum, modulating molecular energy levels, and other well-studied properties, a stronger intramolecular electron push-pull effect also affords other advantages in nonfullerene acceptors. A strong push-pull effect improves the dipole moment… read more here.

Enaminone‐Based Push–Pull Chromophores: Synthesis, Optical Properties, and Computational Insights
Sign Up to like & getrecommendations! Published in 2025 at "Asian Journal of Organic Chemistry"
DOI: 10.1002/ajoc.202500071
Abstract: Chromophores incorporating enaminone units were efficiently synthesized using click‐type [2+2] cycloaddition‐retroelectrocyclization (CA‐RE) reactions. The preparation of electron‐rich alkynes necessary for these reactions initiated with the synthesis of alkynones via Sonogashira cross‐coupling, followed by nucleophilic conjugate… read more here.

DOI: 10.1002/cplu.202400320
Abstract: Multifluorinated aromatics serve as supramolecular synthons in the research of organic electro-optic (EO) materials by exploiting π-π stacking interaction between the aromatic hydrocarbon and multifluorinated aromatic groups for performance improvement. However, non-classical hydrogen bonding remains… read more here.
