Exploring the Photophysical Processes of an Al3+ Sensor Based on Schiff Base
ChemPhysChem, EarlyView.Multiple excited‐state intramolecular proton transfer (ESIPT) processes and twisted intramolecular charge transfer (TICT) states are observed on the S1 state potential energy surface of an Al3+ sensor. The ESIPT process induces an ultrafast CC rotation process and leads to a non‐emissive TICT state.

On the negative coupling O(N) model in 2d at high temperature
Journal of High Energy PhysicsIn this work, I consider N-component scalar quantum field theory in two dimensions interacting with an upside-down quartic potential. Working in the large N limit, the model can be solved non-perturbatively using the saddle-point method for sufficiently ...

ChemPhotoChem, EarlyView.Strain‐promoted, double alkyne‐azide 1,3‐dipolar cycloadditions make dibenzo‐cycloocta‐bis‐triazoles which display a form of chirality that to date has been overlooked. The enantiomers can be resolved, with their remarkably high configurational stability being exemplified through a chiral fluorescent example.

ChemSusChem, EarlyView.Molecular solar thermal systems urge for innovative building blocks to increase their present limits in storage density and light activation window. Here, a complete computational study of loading and unloading mechanisms for an experimentally inspired system based on the Paternò–Büchi reaction is presented.
