Controlling the Guanidinium Cation Rotation by Cation–π Interactions

Angewandte Chemie International Edition, EarlyView.
A lanthanide π‐container has been employed to trap a guanidinium cation inside the aromatic cavity by cation–π interactions. X‐ray crystallography and solid‐state nuclear magnetic resonance (NMR) spectroscopy at fast magic‐angle spinning (MAS) frequencies have been utilized to probe the underlying host–guest interactions.

Quantum Heat Current in Terahertz‐Driven Phonon Systems

Advanced Physics Research, EarlyView.
We develop a quantum mechanical description of ultrafast thermodynamics on the example of a laser‐excited phonon mode. We show that the resulting quantum heat current exhibits non‐Markovian dynamics, which can be controlled by the pulse length. ABSTRACT The advent of high‐intensity ultrafast laser pulses has opened new opportunities for controlling and

Spin Dynamics of Excitons and Carriers in Mixed‐Cation MAxFA1–xPbI3 Perovskite Crystals: Alloy Fluctuations Probed by Optical Orientation

Advanced Physics Research, EarlyView.
The impact of alloy fluctuations on the spin dynamics of mixed‐cation MAxFA1‐xPbI3 perovskite single crystals is studied experimentally by means of polarized time‐resolved photoluminescence. The high optical orientation degree, reaching 80% for x = 0.1 and 0.8, displays a minimum of 60% for x = 0.4.
