Supramolecular Chemistry in Metal–Organic Framework Materials

Advanced Materials, EarlyView.
This review highlights synergies between reticular chemistry and supramolecular chemistry. The role of supramolecular interactions in determining framework…guest interactions and attempts to understand dynamic behavior in metal–organic frameworks (MOFs), particularly emphasizing the development of crystal sponges, studying reactions in frameworks and ...

1-{(E)-[(2E)-3-(4-Methoxyphenyl)-1-phenylprop-2-en-1-ylidene]amino}-3-phenylurea: crystal structure and Hirshfeld surface analysis

Acta Crystallographica Section E: Crystallographic Communications, 2017
The title compound, C23H21N3O2, is constructed about an almost planar disubstituted aminourea residue (r.m.s. deviation = 0.0201 Å), which features an intramolecular amine-N—H...N(imine) hydrogen bond.

Can Europium Atoms form Luminescent Centres in Diamond: A combined Theoretical-Experimental Study

, 2019
The incorporation of Eu into the diamond lattice is investigated in a combined theoretical-experimental study. The large size of the Eu ion induces a strain on the host lattice, which is minimal for the Eu-vacancy complex.

Free‐Standing Supramolecular Pyridine N‐Oxide‐Silver(I) Metallogels

Advanced Materials, EarlyView.
A comprehensive analysis of pyridine N‐oxide‐silver(I) trifluoroacetate complexes reveals remarkable mechanical strengths that enable the creation of free‐standing objects with shape control, reaching dimensions of up to centimeters and shedding new insights into the gelation mechanisms.

Divergent Synthesis and Crystal Engineering of Room‐Temperature Phosphorescent Carbonyl‐Bridged Triphenylamines

Angewandte Chemie, EarlyView.
Solid state packing of triphenylamine derivatives is modulated by the variation of aryl bridges, endowing a wide diversity of luminescence properties. Closely packed, parallel structures induce room temperature phosphorescence (RTP) dominated spectra with long RTP lifetimes (τPh), while nonparallel, more spaced motifs result in competitive fluorescence

Crystal structure and Hirshfeld analysis of the kryptoracemate: bis(mefloquinium) chloride p-fluorobenzenesulphonate [PDF]

, 2016
The crystal structure analysis of the bis(mefloquinium) chloride p-fluorobenzenesulphonate salt reveals a rare example of a kryptoracemate given that the cations exhibit a non-crystallographic enantiomeric relationship.

Ion Valency as a Molecular Switch for Salt‐Resistant Underwater Adhesion

Advanced Materials, EarlyView.
Monovalent K+ ions weaken adhesion by forming K+‐π complexes with weak bridging capacity. In contrast, multivalent cations like Y3+ enhance adhesion by forming stable π‐cation‐π bridging networks, which are resistant to salt and capable of compensating for the loss of native π–π and NH3+‐π interactions.

Doping of Graphene Nanoribbons via Functional Group Edge Modification

, 2017
We report on the on-surface synthesis of 7 armchair graphene nanoribbons (7-AGNRs) substituted with nitrile (CN) functional groups. The CN groups are attached to the GNR backbone by modifying the 7-AGNR precursor.
