Eu(III) complexes

Our new paper “Impact of Varying the Phenylboronic Acid Position in Macrocyclic Eu(III) Complexes on the Recognition of Adenosine Monophosphate“, led by S. E. Bodman and S. J. Butler from Loughborough, just appeared in Organic Chemistry Frontiers. The paper is the second in a series studying the anion sensing properties of Eu(III) complexes with phenylboronic acids.

Aside from reporting the synthesis and anion binding, the paper presents new strategies for the computational analysis of such complexes. Aside from modelling the geometries by density functional theory, high-level multireference methods in OpenMolcas were applied to study the luminescence properties. These first principles computations offer a promising approach to access the emission spectra of lanthanide complexes, aiding the design of responsive lanthanide probes with specific photophysical properties

Substituted macrocycles

A recent study, lead by Florian Glöcklhofer from Imperial College London, explores the effect of methoxy and thiomethyl subtitutions on a formally antiaromatic macrocycle. The corresponding paper “[]Paracyclophanetetraenes (PCTs): cyclic structural analogues of poly(p‑phenylene vinylene)s (PPVs)” is available via Open Research Europe, 1, 111, 2012.

The above figure compares the orbitals and aromaticity descriptors for different charge and spin states. Importantly, the symmetry is broken in the T1 state, inhibiting Baird aromaticity. By comparison, the symmetry is retained for the neutral singlet, dianion, and dication states all of which exhibit aromaticity.

Reversible P-P bond cleavage

Recent work out of the group of Martin Smith at Loughborough University presents the possibility of cleaving a P-P bond at an iridium(III) metal centre by adding an AuCl unit.

Computations elucidate the underlying energetics and rationalise the results using the natural bond orbitals (NBO) approach.

Luminescent lanthanide probes

Recent research led by Samantha Bodman and Steve Butler from Loughborough University presents a luminescent lanthanide probe with selective affinity for adenosine monophosphate (AMP), able to differentiate AMP from the more highly charged analogues ADP and ATP.

Density functional theory computations shed insight onto the binding modes involved.
