Abstract
![]()
We
demonstrate the formation of uniform and oriented metal–organic
frameworks using a combination of anion effects and surface chemistry.
Subtle but significant morphological changes result from the nature
of the coordinative counteranion of the following metal salts: NiX2 with X = Br–, Cl–, NO3–, and OAc–. Crystals
could be obtained in solution or by template surface growth. The latter
results in truncated crystals that resemble a half structure of the
solution-grown ones. The oriented surface-bound metal–organic
frameworks (sMOFs) are obtained via a one-step solvothermal approach
rather than in a layer-by-layer approach. The MOFs are grown on Si/SiOx
substrates modified with an organic monolayer or on glass substrates
covered with a transparent conductive oxide (TCO). Regardless of the
different morphologies, the crystallographic packing is nearly identical
and is not affected by the type of anion or by solution versus the
surface chemistry. A propeller-type arrangement of the nonchiral ligands
around the metal center affords a chiral structure with two geometrically
different helical channels in a 2:1 ratio with the same handedness.
To demonstrate the accessibility and porosity of the macroscopically
oriented channels, a chromophore (resorufin sodium salt) was successfully
embedded into the channels of the crystals by diffusion from solution,
resulting in fluorescent crystals. These “colored” crystals displayed polarized emission (red) with a high
polarization ratio because of the alignment of these dyes imposed
by the crystallographic structure. A second-harmonic generation (SHG)
study revealed Kleinman symmetry-forbidden nonlinear optical properties.
These surface-bound and oriented SHG-active MOFs have the potential
for use as single nonlinear optical (NLO) devices.

Abstract
Large-scale targeted exploration of metal–organic frameworks (MOFs) with characteristics such as specific surface chemistry or metal-cluster family has not been investigated so far.
Large-scale targeted exploration of metal–organic frameworks (MOFs) with characteristics such as specific surface chemistry or metal-cluster family has not been investigated so far. These definitions are particularly important because they can define the way MOFs interact with specific molecules (e.g. their hydrophilic/phobic character) or their physicochemical stability. We report here the development of algorithms to break down the overarching family of MOFs into a number of subgroups according to some of their key chemical and physical features. Available within the Cambridge Crystallographic Data Centre's (CCDC) software, we introduce new approaches to allow researchers to browse and efficiently look for targeted MOF families based on some of the most well-known secondary building units. We then classify them in terms of their crystalline properties: metal-cluster, network and pore dimensionality, surface chemistry (i.e. functional groups) and chirality. This dynamic database and family of algorithms allow experimentalists and computational users to benefit from the developed criteria to look for specific classes of MOFs but also enable users – and encourage them – to develop additional MOF queries based on desired chemistries. These tools are backed-up by an interactive web-based data explorer containing all the data obtained. We also demonstrate the usefulness of these tools with a high-throughput screening for hydrogen storage at room temperature. This toolbox, integrated in the CCDC software, will guide future exploration of MOFs and similar materials, as well as their design and development for an ever-increasing range of potential applications.
