Chiral transfer in coordination complexes: towards molecular materials
TL;DR: In this critical review, examples of coordination complexes with efficient chiral transfer determining stereochemistry at the metal centre and throughout the overall molecular assembly are presented.

A synthetic molecular pentafoil knot
Jean François Ayme,Jonathon E. Beves,David A. Leigh,Roy T. McBurney,Kari Rissanen,David Schultz +5 more
TL;DR: The synthesis of the most complex non-DNA molecular knot prepared to date, which features an exceptional number of different design elements within the context of directing the formation of (supra)molecular species, is reported on.

Photoinduced intramolecular electron transfer in ruthenium and osmium polyads: insights from theory.
TL;DR: The possibility of a direct ET from the ground state to the targeted *[P-A-] CS state is theoretically postulated and found to be consistent with available photophysical data (transient absorption spectroscopy), and the occurrence of a quinoidal-like electronic redistribution inherent to the photoreduced acceptor-ligand is proposed to favor efficient charge recombination.

Optically pure, water-stable metallo-helical ‘flexicate’ assemblies with antibiotic activity
Suzanne E. Howson,Albert Bolhuis,Viktor Brabec,Guy J. Clarkson,Jaroslav Malina,Alison Rodger,Peter Scott +6 more
TL;DR: This work's highly adaptable self-assembly approach enables the rapid preparation of ranges of water-stable, helicate-like compounds with high stereochemical purity, and one such iron(II) 'flexicate' system exhibits specific interactions with DNA, promising antimicrobial activity against a Gram-positive bacterium but also, unusually, a gram-negative bacterium.

TL;DR: In this article, the enantioselective template effect of optically active cations was used to construct 3D anionic networks in which transition metal ions (Cr−Mn) and transition metal ion(Cr−Ni) are connected by oxalate ligands (ox).

On the Theory of Dispersion of X-Rays
TL;DR: In this article, a general formula for the index of refraction in terms of the atomic absorption coefficient α and the critical frequencies is given, from the condition, experimentally verified, that the electrons in the atom for impressed frequencies, large compared to their natural frequencies, shall act like free electrons as far as the index is concerned, a relation is obtained for α.
