On-surface light-induced generation of higher acenes and elucidation of their open-shell character

Nature Communications, 2019
The synthesis of large acenes via traditional solution-chemistry routes is hindered by their poor solubility and high reactivity under ambient conditions.

Hot dissociation, hole shrinkage, and hole re-delocalization in P3HT/PCBM organic photovoltaics [PDF]

, 2023
Despite recent progress in increasing the power conversion efficiencies of organic photovoltaics, the mechanism behind charge separation against Coulombic attractions remains unclear. To date, studies have emphasized both ultrafast charge transfer and/or

Controlling Chemical Reactions in Confined Environments: Water Dissociation in MOF-74

Applied Sciences, 2018
The confined porous environment of metal organic frameworks (MOFs) is an attractive system for studying reaction mechanisms. Compared to flat oxide surfaces, MOFs have the key advantage that they exhibit a well-defined structure and present significantly

Redox driven B12-ligand switch drives CarH photoresponse

Nature Communications, 2023
CarH is a coenzyme B12-dependent photoreceptor involved in regulating carotenoid biosynthesis. How light-triggered cleavage of the B12 Co-C bond culminates in CarH tetramer dissociation to initiate transcription remains unclear. Here, a series of crystal

Chemistry in Quantum Cavities: Exact Results, the Impact of Thermal Velocities, and Modified Dissociation [PDF]

The Journal of Physical Chemistry Letters, 2020
In recent years tremendous progress in the field of light-matter interactions has unveiled that strong coupling to the modes of an optical cavity can alter chemistry even at room temperature. Despite these impressive advances, many fundamental questions of chemistry in cavities remain unanswered.

Quantum chemical and microkinetic study of H2 dissociation on Cu4 cluster in the gas phase [PDF]

, 2023
Here we study the H2 dissociation mechanism on cationic and neutral Cu4 clusters using master equation based microkinetic modelling. Cationic cluster hinders the H2 dissociation compared to the neutral one.
