Helical electronic transitions of spiroconjugated molecules

Marc Hamilton Folkmann Garner

The two pi-systems of allene can combine into helical molecular orbitals (MOs), yet the helicity is lost in the pi-pi* transitions due to excited state mixing. In spiroconjugated molecules the relative orientation of the two pi-systems is different and con ...

Building a Consistent and Reproducible Database for Adsorption Evaluation in Covalent-Organic Frameworks

Berend Smit, Daniele Ongari, Christoph Leopold Talirz, Aliaksandr Yakutovich

We present a workflow that traces the path from the bulk structure of a crystalline material to assessing its performance in carbon capture from coal's postcombustion flue gases. This workflow is applied to a database of 324 covalent-organic frameworks (CO ...

Force Field Development from Periodic Density Functional Theory Calculations for Gas Separation Applications Using Metal-Organic Frameworks

Berend Smit, Rocio Mercado, Yongjin Lee, Miguel Gonzalez

We present accurate force fields developed from density functional theory (DFT) calculations with periodic boundary conditions for use in molecular simulations involving M-2(dobdc) (M-MOF-74; dobdc(4-) = 2,5-dioxidobenzenedicarboxylate; M = Mg, Mn, Fe, Co, ...

Capturing Non-local Effects in Kohn-Sham Density Functional Theory

Andrey Laktionov

Density Functional Theory (DFT) and its time-dependent extension (TDDFT) have become two of the most popular approaches for computer simulations of the electronic structure and response properties of quantum systems. A reasonable compromise between accurac ...

Structure-Correlation Principles Connecting Ground State Properties and Reaction Barrier Heights for the Cope Rearrangement of Semibullvalenes

Matthew Wodrich, Daniel Filipe Dos Santos Alves Jana

A direct relationship exists between the properties of substituted semibullvalenes and their Cope rearrangement activation barrier. This unique correlation not only enables the determination of kinetic data from ground state information, but also provides ...

Chiral recognition and supramolecular self-assembly of adsorbed amino acids and dipeptides at the submolecular level

Magalí Alejandra Lingenfelder

This thesis deals with the supramolecular organization of chiral aminoacids and dipeptides on metal surfaces. The emergence of homochirality in biomolecular systems is one of the most intriguing open questions of Nature. The self-assembly and amplification ...

Combinatorial synthesis of bimetallic complexes with three halogeno bridges

Kay Severin, Sébastien Gauthier, Laurent Quebatte

Methods for the synthesis of bimetallic complexes in which two different metal fragments are connected by three chloro or bromo bridges are reported. The reactions are general, fast, and give rise to structurally defined products in quantitative yields. Th ...

Parametrization of substituents: effects of fluorine and other heteroatoms on OH, NH, and CH acidities

Fluorine leaves nobody indifferent; it inflames emotion, be that affections or aversions. As a substituent it is rarely boring, always good for a surprise, but often completely unpredictable. It behaves nonconformingly even when fundamental properties such ...
