Stereoselective synthesis of heterocyclic tetraphenylethylene analogues with configuration-dependent solid-state luminescence Open
Stereopure AIEgens based on a ditriazolostilbene core are synthesized, enabling E / Z isomer comparison with detailed investigation of their solid-state luminescence and elucidation of the origin of their photophysical behavior.

π-Expansion as gateway to viologen-based pimers Open
Elusive pimer! Therein, we report a new and efficient synthetic strategy towards tetracene-bipyridiniums as well as the first observation of a mixed valence complex (pimer) formed in solution from an unconstrained bis-viologen-like derivat…

Issue Information Open
The Superatom Molecular Orbitals (SAMO) in fullerene derivatives are of great interest, providing a wide basement for many electronic applications.Endohedral doping of C 80 lowers s-SAMO energy where Co@C 80 constitutes the lowest SAMO ene…

Modeling the polychromism of oxide minerals: The case of alexandrite and cordierite Open
In this work, we investigate the spectroscopic properties of photochromic alexandrite and cordierite by TD‐DFT. The objective is to assess the TD‐DFT for the simulation of pleochroism (change of color depending on the crystallographic dire…

Highly Tuneable Photochromic Sodalites for Dosimetry, Security Marking and Imaging Open
Photochromic sodalites are considered for a plethora of possible applications, such as UV indexing and X‐ray imaging, but for many of these the materials are yet to be optimized. UV indexing can be improved through incremental adjustment o…
