Organic chemists tend to consider the conformation of compounds as a consequence of
repulsive steric interactions. In other words,“the steric effect” means “repulsive” in many …

Conspectus Molecules and materials can show dynamic structures in which the dominant
mechanism is rotary motion. The single mobile elements are defined as “molecular rotors” …

The assembly of cluster-based π-stacked porous supramolecular frameworks presents
daunting challenges, including the design of suitable cluster building units, control of the …

The CH/π hydrogen bond is an attractive molecular force occurring between a soft acid and
a soft base. Contribution from the dispersion energy is important in typical cases where …

This treatise is an update to a preceding highlight (CH/π hydrogen bonds in crystals)
published in this journal 5 years ago (M. Nishio, CrystEngComm, 2004, 6, 130–156). After …

Interest in green chemistry and clean processes has grown so much in recent years that
topics such as fluorous biphasic catalysis, metal organic frameworks, and process …

The first molecular crystal showing permanent porosity, made by of tris-o-
phenylenedioxycyclotriphosphazene TPP molecules, is presented. The empty-pore …

A new aluminum naphthalenedicarboxylate Al (OH)(1, 4-NDC)· 2H2O compound has been
synthesized. The crystal structure exhibits a three-dimensional framework composed of …

In recent years, a new class of porous materials based on a combination of organic
components and metal centers has emerged, called porous coordination polymers (PCPs) …

High surface area 3D polymers represent one of the most promising classes of porous
materials because of their high gas uptake and stability to thermal and chemical …
