Abstract Molecular doping of conjugated polymers causes bleaching of the neutral absorbance and results in new polaron absorbance transitions in the mid and near infrared. Here, the concentration dependent changes in the spectra for a series of molec

© 2019 American Chemical Society. Molecular dopants are increasingly studied to enhance the conductivity of semiconducting polymers. Most available p-type dopants have low solubility in common solvents and moderate electron affinities (EA), which ma

Generally, the long-range electronic communication between spatially orthogonal orbitals is inefficient and limited to field and inductive effects. In this work, we provide experimental evidence that such communication can be achieved via intramolecu

A Friedel–Crafts-type alkylation reaction was studied between various pyrroles and α-polyfluoroalkylated cyclic imines that were activated by Lewis acids. The reaction proceeded under mild conditions and provided a high yielding synthesis of α-CF
