Advances in flexible and functional metal–organic frameworks (MOFs), also called soft
porous crystals, are reviewed by covering the literature of the five years period 2009–2013 …

Negative thermal expansion (NTE) is the phenomenon in which materials shrink rather than
expand on heating. Although NTE had been previously observed in a few simple materials …

Recent years have seen a large increase of the research effort focused on framework
materials, including the nowadays-ubiquitous metal–organic frameworks but also dense …

While all materials reduce their intrinsic volume under hydrostatic (uniform) compression, a
select few actually expand along one or more directions during this process of densification …

Materials with negative linear compressibility are sought for various technological
applications. Such effects were reported mainly in framework materials. When heated, they …

Abstract Knowledge of the thermodynamic potential in terms of the independent variables
allows to characterize the macroscopic state of the system. However, in practice, it is difficult …

Temperature-responsive flexibility in metal-organic frameworks (MOFs) appeals to the
imagination. The ability to transform upon thermal stimuli while retaining a given crystalline …

We report here a new class of ammonium metal–formate frameworks of [NH2NH3][M
(HCOO) 3](M= Mn2+, Zn2+, Co2+ and Mg2+) incorporating hydrazinium as the cationic …

Auxetics display the anomalous property of expanding laterally when uniaxially stretched,
that is, a negative Poisson's ratio, a property that arises from 1) the presence of specific …

Metal–organic frameworks (MOFs) are a broad and interesting class of materials known for
their mechanical flexibility. As such, their response to pressure is usually extreme and often …
