Exploring the Photophysical Processes of an Al3+ Sensor Based on Schiff Base

open access: yesChemPhysChem, 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 CC rotation process and leads to a non‐emissive TICT state.

On the negative coupling O(N) model in 2d at high temperature

open access: yesJournal of High Energy Physics
In 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 ...

Double Click for Chirality: Chiral Dibenzo‐cycloocta‐bis‐triazoles via Strain‐Promoted Alkyne‐Azide Cycloaddition

open access: yesChemPhotoChem, 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.

Designing Molecular Solar Thermal Systems Based on the Paternò–Büchi Reaction Coupled to Enzymatic Energy Release

open access: yesChemSusChem, 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.
