This review focuses on a new generation of polymers with intrinsic microporosity (PIMs) and their hydrogen storage applications. PIMs are a novel microporous material attracting attention due to their potentially useful functional properties. In this review, the methods of synthesis, suitable characterisation techniques and applications are briefly described. Importantly, the hydrogen capacity of PIMs that have been investigated recently is highlighted and the hydrogen uptake is compared to other microporous materials such as hypercrosslinked polymers (HCPs), metal organic frameworks (MOFs) and activated carbons. This review brings H2storage-applicable PIMs that have been reported in different studies together for the first time, providing a reference for better comparison of H2storage in PIMs.

The family of dyes of the invention are fluoresceins and rhodols that are directly substituted on one or more aromatic carbons by fluorine. These fluorine-substituted fluorescent dyes possess greater photostability and have lower sensitivity to pH changes in the physiological range of 6-8 than do non-fluorinated dyes, exhibit less quenching when conjugated to a substance, and possess additional advantages. The dyes of the invention are useful as detectable tracers and for preparing conjugates of organic and inorganic substances.

A new class of potent antihypertensives has been discovered that exert their effect through blockade of the angiotensin II (AII) receptor.Most AII antagonists reported so far are peptide mimics of the endogenous vasoconstrictor octapeptide angiotensin II.The compounds of this paper are nonpeptides and therefore constitute a new class of potent AII receptor antagonists.Based on the overlap of a conformation of AII with literature lead 3, a hypothesis was developed suggesting the need for an additional acidic functionality to increase the lead’s potency.The substitution of an additional carboxylic acid resulted in a 10-fold increase in binding affinity observed for diacid 4.The binding affinities for subsequent compounds were eventually increased 1000-fold over that of the literature leads through a systematic SAR study.Thus the AII receptor binding affinity of 15 muM for literature lead 1, for example, was increased to 0.018 and 0.012 muM for compounds 33 and 53.A structure-affinity relationship has been found requiring the presence of four key elements for good activity: (1) an additional phenyl ring at the N-benzyl para position of the benzylimidazole nucleus, (2) an acidic functionality at the ortho position of the terminal aromatic ring, (3) a lipophilic side chain at the imidazole 2-position of three to five carbon atoms in length, and (4) a group at the imidazole 5-position capable of hydrogen bonding.The synthesis as well as the pharmacological activity of the compounds in this new series of AII receptor antagonists are presented.

A novel heteroacene, 2-(2,3,4,5-tetrafluorophenyl)-1H-imidazo[4,5-b] phenazine has been successfully synthesized. The heteroacene can selectively detect F- over Cl-, Br-, I-, NO 3-, HSO4-, ClO4 -, and BF4- in organic solvents through colorimetric and fluorescent responses. The interaction between the heteroacene and F- was investigated through UV-Vis, fluorescence, and 1H NMR titration experiments, which suggested that the effects might occur via a combined process including hydrogen bond, deprotonation, and anion-pi interactions between the sensor and F-.

Developing new compounds targeting virulence factors (e.g., inhibition of pilus assembly by pilicides) is a promising approach to combating bacterial infection. A high-throughput screening campaign of a library of 17500 small molecules identified 2-amino-3-acyl-tetrahydrobenzothiophene derivatives (hits 2 and 3) as novel inhibitors of pili-dependent biofilm formation in a uropathogenic Escherichia coli strain UTI89. Based on compounds 2 and 3 as the starting point, we designed and synthesized a series of structurally related analogs and investigated their activity against biofilm formation of E. coli UTI89. Systematic structural modification of the initial hits provided valuable information on their SARs for further optimization. In addition, small structural changes to the parent molecules resulted in low micromolar inhibitors (20-23) of E. coli biofilm development without an effect on bacterial growth. The hit compound 3 and its analog 20 were confirmed to prevent pili formation in a hemagglutination (HA) titer assay and electron microscopy (EM) measurements. These findings suggest that 2-amino-3-acyl-tetrahydrobenzothiophenes may serve as a new class of compounds for further elaboration as antibacterial agents with antivirulence activity.

A synthetic entry to derivatives of the new classes of 5-phthalimidouracils and 5-phthalimidobarbituric acids is reported. These 5-phthalimidopyramines as well as phthalimido-2,4-difluorobenzenes were designed as analogues of thalidomide, a well known inhibitor of TNF-alpha production. A preliminary in vitro investigation of the compounds as inhibitors of the TNF-alpha production was performed. Among the compounds of the present series, (5-ethyl-1-phenyl-5- tetrafluorophthalimido)barbituric acid and (2- 2,4-difluorophenyl)-4,5,6,7-tetrafluoro-1H-isoindole-1,3 2H)-dione were proved to be potent inhibitors. Both compounds showed inhibitory activity in the lower micromolar range of the LPS-induced TNF-alpha production in human monocytes. Copyright

A practical general method for asymmetric intermolecular benzylic C(sp3)?H amination has been developed by combining the pentafluorobenzyl sulfamate PfbsNH2 with the chiral rhodium(II) catalyst Rh2(S-tfptad)4. Various substrates can be used as limiting components and converted to benzylic amines with excellent yields and high levels of enantioselectivity. Additional key features for the reaction are the low catalyst loading and the ability to remove the Pfbs group under mild conditions to give NH-free benzylic amines.

A series of unsymmetrical dyes containing a naphthyl unit connected to an electron acceptor moiety was designed and synthesised. By modifying the electron acceptor unit, a shift of the LUMO energy level as well as its distribution through the molecule were achieved. These dyes were fully characterised by optical, computational and electrochemical techniques. In addition, crystal structures reveal different packing depending upon the nature of the acceptor. Their potential use as electron acceptor materials for organic photovoltaics (OPVs) was also investigated by photoluminescence studies of blends with the common OPV polymers P3HT and PCDTBT. A series of unsymmetrical dyes was synthesised and characterised. Their optical and electrochemical properties were tuned by modifying the electron acceptor unit. Copyright
