Synthesis and study of new photochromic spiropyrans modified with carboxylic and aldehyde substituents

Three new photochromic spiropyrans containing a carboxylic group in the indoline fragment and an aldehyde substituent in the [2H]-chromene moiety were synthesized. The structure of the compounds obtained was studied using 1H and 13C NMR, IR and elemental analysis. Single crystal X-ray analysis was used to refine the molecular structure of 8′-formyl-1,3,3,6′-tetramethyl-spiro[indoline-2,2′-2H-chromene]-5-carboxylic acid. It was found out that in the solid state the molecules of that compound are arranged in dimeric associates due to the formation of intermolecular hydrogen bonds between carboxylic groups of two adjacent molecules. All the spiropyrans were shown to be photochromic with the lifetimes of the open forms in the range of 1.5–46.0 s.

Bis-Schiff base as a donor-acceptor fluorescent probe: Recognition of Al3+ ions in near 100% aqueous solution

In this paper, a novel bis-Schiff base fluorescent probe (HL) for Al3+ has been designed and synthesized on the basis of the mechanism of internal charge transfer (ICT). Compared with the free receptor, the fluorescence intensity of HL shows si

A rare 4-fold interpenetrated metal-organic framework constructed from an anionic indium-based node and a cationic dicopper linker

A unique 4-fold interpenetrated metal-organic framework, TIF-1, was synthesized by combining an anionic indium node with a cationic linker. This framework shows a rare type of 4-fold interpenetrated dia network, constructed from tessellation of biangular and tetragonal type metal-organic micropores. The porosity of TIF-1 is moderate due to four-fold interpenetration and charge-balancing anions. The cationic feature of this MOF may give good efficiency for selective small anion exchange or separation. In addition, the thermal stability and moderate CO2 adsorption property of the complex were studied.

Synthesis of Monofunctionalized Calix[5]arenes

Seven OH-free and O -permethylated monofunctionalized calix[5]arenes carrying either additional methyl or tert -butyl groups are prepared following fragment condensation protocols. This strategy proves to be superior to previous approaches. Calix[5]arenes with free OH groups all adopt a cone conformation stabilized by a seam of hydrogen bonds at the lower rim. Post-condensation modifications, i.e., methylation of phenolic OH groups or functional group interconversions can also be achieved. Bulky tert -butyl groups are also found to stabilize the cone conformations of O -methylated compounds. These compounds offer versatile functional groups that make these concave molecules interesting building blocks for the synthesis of more sophisticated molecular architectures.

A new metal-organic framework constructed from cationic nodes and cationic linkers for highly efficient anion exchange

A novel cationic metal-organic framework, FJI-Y6, was designed and constructed by combining [In3O(COO)6(H2O)3]+ with cationic linkers. FJI-Y6 exhibits highly efficient anion exchangeability. For example, Acid orange 7, with a single negative charge and which cannot be adsorbed effectively by previously reported MOFs, is captured and released rapidly by FJI-Y6.

Relationship between mechanochromic behavior and crystal structures in donor-π-acceptor compounds consisted of aromatic rings with ester moiety as an acceptor

We investigated the mechanochromic behavior of donor-π-acceptor compounds which consisted of diphenylaminophenylacetylene as a donor-π moiety and (hetero)aromatic ring bearing ester as an acceptor. The compounds with dicyanobenzoic ester gave the bathochr

Synthesis of the TACO scaffold as a new selectively deprotectable conformationally restricted triazacyclophane based scaffold

The synthesis of a new triazacyclophane scaffold (TACO scaffold) containing three selectively deprotectable amines is described. The TACO scaffold is conformationally more constrained than our frequently used TAC scaffold, due to introduction of a substituent on the para position of the benzoic acid hinge, which prevents ring flipping and makes it more attractive than the TAC scaffold for preparation of artificial receptor molecules or for mimicking discontinuous epitopes toward protein mimics when more preorganization is required.

Development of bis(2-picolyl)amine-zinc chelates for imidazole receptors

New phenyl and phenol bis(2-picolyl)amine (Dpa) derivatives have been synthesized in order to generate zinc chelates for imidazole anion receptors. Previously, binuclear phenolic zinc and copper chelates have shown affinity for pyrophosphate and guanidine anions, respectively. Herein we report significant imidazole affinity increasing from 2.38 × 106 to 2.90 × 107 for phenol-bridged binuclear zinc-Dpa chelates, as evidenced by dynamic and titration 1H NMR studies. Among the Dpa chelates investigated, the zinc-coordinated phenol group plays a crucial role in the mechanism of anion binding. Low-temperature 1H NMR experiments suggest a σν-symmetric geometry for the imidazole chelate. Computational DFT studies at the B3LYP level of theory imply that imidazole binding displaces the phenol bridge between the zinc ions. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
