Poly(dimethylsiloxane) and oligo(dimethylsiloxane) solvent effects on aromatic donor-acceptor interactions

Solvents with a wide range of polarities, including poly(dimethylsiloxane) and oligo(dimethylsiloxane), were used to evaluate aromatic donor-acceptor interactions between pyrene and pyromellitic diimide derivatives. The donor-acceptor interactions were stronger in siloxane solvents than in aliphatic solvents, possibly because of the poor solubility of the aromatics in siloxanes.

Automated summary

The study showed that the aromatic donor-acceptor interactions between pyrene and pyromellitic diimide derivatives were stronger in siloxane solvents compared to aliphatic solvents due to the poor solubility of the aromatics in siloxanes.
