Chalcogen‐Guided Control of Azoarene Photoswitching: Tuning Excited‐State Energies Through Electronic Property Modulation

open access: yesChemistry – A European Journal, EarlyView.
Photophysical properties of ortho‐tellurium‐substituted azoarenes are tunable via aryl substituent electronics and tellurium oxidation state. Electron‐donating groups destabilize the excited state three‐electron σ bond, enhancing photoisomerization.

Polarization and Dipole Moment Effects on Sigma‐Hole Potential in Tin(IV)‐Porphyrins

open access: yesChemistry – A European Journal, EarlyView.
Through this work with experimental and computational studies we have systematically investigated the role of interplay of electronic effects such as polarization, dipole moment and resonance on the sigma‐hole potential in macrocyclic system like, metalloporphyrin system.

Symmetric Bis‐Kryptopyrrol‐2‐Yl Squaraine as a Viscosity Probe and Dual‐State Emitter

open access: yesChemPhotoChem, EarlyView.
Previously unknown capabilities of one of the original squaraine dyes as a viscosity probe and dual‐state emitter are revealed, with aggregated forms of the dye being responsible for the near‐IR emission in the solid state. Easily accessible small organic fluorophores with multiplexing capabilities are of interest for a variety of fields.

A Simple Micellar Gold Catalyst Supported by a Hydrophilic Phosphinoferrocene Amidosulfonate Ligand

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
A phosphinoferrocene amidosulfonate and its chlorogold complex form micelles in water. The complex can be used as a self‐activating Au catalyst, as demonstrated for the model cyclization of N‐propargyl benzamide into 4,5‐dihydro‐5‐methylene‐2‐phenyloxazole.
