Optical gap and fundamental gap of oligoynes and carbyne

Jan Cornelius Brauer, Laurent Alexis Clément Vannay, Anne-Clémence Corminboeuf, Holger Frauenrath, Stephen Schrettl, Emmanuel Romaric Contal, Eric Albert Georges Bremond

The optoelectronic properties of various carbon allotropes and nanomaterials have been well established, while the purely sp-hybridized carbyne remains synthetically inaccessible. Its properties have therefore frequently been extrapolated from those of def ...

The nature of vertical excited states of dyes containing metals for DSSC applications: insights from TD-DFT and density based indexes

Eric Albert Georges Bremond

Transition metal complexes, typically Ru-based complexes, are the most efficient dyes used in dye-sensitized solar cells. The absorption spectra of these molecules generally involve numerous electronic transitions, which are not equivalent for the conversi ...

Communication: Double-hybrid functionals from adiabatic-connection: The QIDH model

Eric Albert Georges Bremond

A new approach stemming from the adiabatic-connection (AC) formalism is proposed to derive parameter-free double-hybrid (DH) exchange-correlation functionals. It is based on a quadratic form that models the integrand of the coupling parameter, whose compon ...

In silico assessment of the HPLC-UV response coefficients

Eric Albert Georges Bremond

A new in silica approach allowing to compute HPLC-UV response coefficients using Time Dependent-Density Functional Theory (TD-DFT) is here reported. Based on the use of a non linear least squares with bound restricted algorithm, this model exploits theoret ...

Adjusting the Local Arrangement of π‑Stacked Oligothiophenes through Hydrogen Bonds: A Viable Route to Promote Charge Transfer

Jérôme Florian Gonthier, Anne-Clémence Corminboeuf, Eric Albert Georges Bremond, Antonio Prlj, Hongguang Liu

We show that substituting quaterthiophene cores with strong H-bond aggregators, such as urea groups, provides an efficient way to adjust the mutual in-plane displacements of the semiconducting units and promote charge transfer. Our 2-D structure-property m ...

How Important is Self-Consistency for the dDsC Density Dependent Dispersion Correction?

Anne-Clémence Corminboeuf, Eric Albert Georges Bremond, Nikolay Golubev

The treatment of dispersion interactions is ubiquitous but computationally demanding for seamless ab initio approaches. A highly popular and simple remedy consists in correcting for the missing interactions a posteriori by adding an attractive energy term ...
