Photocatalytic Solar Hydrogen Peroxide Production on Donor+Acceptor Linear Polymer Semiconductor Powders Reconfigurable by H‐Bonding and π‐Stacking Interactions

open access: yesAngewandte Chemie International Edition, EarlyView.
A linear polymer, poly(2,3‐dihydroxynaphthalene), when insolubilized, leads to self‐assembly into a hydroquinone–quinone donor+acceptor semiconducting architecture through H‐bonding and π‐stacking interactions. The polymer behaves as a heterogeneous photocatalyst in water for H2O2 production via water oxidation and O2 reduction under visible light.

Temporal variations of solar rotation during solar cycle 23

open access: yes, 2006
With 11 years of helioseismic data now available, we study the temporal variation in rotation rate in the solar interior. In addition to the well known zonal flow pattern, we also find that at low latitudes the pattern is shifting upwards with time and ...

Controlling the Guanidinium Cation Rotation by Cation–π Interactions

open access: yesAngewandte 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.
