Photochemistry of 1- and 2-Naphthols and their Water Clusters: The Role of 1ππ*(La) Mediated Hydrogen Transfer to Carbon Atoms

Anne-Clémence Corminboeuf, Antonio Prlj

The computational analysis of isomer- and conformer- dependent photochemistry of 1- and 2-naphthols and their microsolvated water clusters is motivated by their very different excited state reactivity. We present evidence that 1- and 2-naphthol follow dist ...

Fluorescence Quenching in BODIPY Dyes: the Role of Intramolecular Interactions and Charge Transfer

Laurent Alexis Clément Vannay, Anne-Clémence Corminboeuf, Antonio Prlj

The fluorescence properties of the BODIPY dye and its two meso-substituted derivatives, tert-butyl- and phenyl-BODIPY, are rationalized. The non emissive behavior of the latter two are attributed to the energetically accessible low-lying conical intersecti ...
