Structural insights into Lewis acid and F4TCNQ doped conjugated polymers by solid-state magnetic resonance spectroscopy

Molecular doping strategies facilitate orders of magnitudes enhancements in the charge carrier mobility of organic semiconductors (OSCs). Understanding the mechanisms of different doping strategies for OSCs and molecular-level constraints on...

Self-evolving materials based on metastable-to-stable crystal transition of polymorphic polyolefin

Living organisms can self-evolve with time in order to adapt to natural environment. Analogically, self-evolving materials also show similar properties based on a non-equilibrium structural transformation. The common design of...

Extended π-backbone for highly efficient near-infrared thermally activated delayed fluorescence with enhanced horizontal molecular orientation

The near-infrared thermally activated delayed fluorescence (NIR-TADF) materials with emission over 700 nm were insufficiently investigated mainly due to the limited choice of strong donor/acceptor units for the molecular construction...
