Metal–Organic Framework-Templated Porous Carbon for Highly Efficient Catalysis: The Critical Role of Pyrrolic Nitrogen Species

Metal–Organic Framework-Templated Porous Carbon for Highly Efficient Catalysis: The Critical Role of Pyrrolic Nitrogen Species

Metal-free catalysis: Metal–organic frameworks (MOFs) are exploited as templates to afford porous carbon materials. Amongst these materials, PCN-224-templated carbon material optimized by pyrolysis at 700 °C exhibits a low activation energy and superior activity to other MOF-derived carbon materials and most metallic catalysts in the catalytic reduction of 4-nitrophenol to 4-aminophenol. Theoretical investigations suggest that the pyrrolic nitrogen species makes the dominant contribution to this activity (see figure).

Dual Chemical Modification of a Polytheonamide Mimic: Rational Design and Synthesis of Ion-Channel-Forming 48-mer Peptides with Potent Cytotoxicity

Atsushi Hayata, Dr. Hiroaki Itoh, Shoko Matsutaka and Prof.Dr. Masayuki Inoue

Dual Chemical Modification of a Polytheonamide Mimic: Rational Design and Synthesis of Ion-Channel-Forming 48-mer Peptides with Potent Cytotoxicity

Simpler but potent: Total synthesis and multiple functional analyses of seven new structurally simplified analogues of polytheonamide B, an ion-channel-forming 48-mer peptide, are reported. Structure–activity studies clarified that the bioactivity of the analogues can be rationally controlled by changing their hydrophobicity at residues 1 and 44 (see figure). The most hydrophobic analogue exhibited the highest cytotoxicity, which is almost as potent as that of polytheonamide B.

A Highly Reactive Geminal P/B Frustrated Lewis Pair: Expanding the Scope to C−X (X=Cl, Br) Bond Activation

Kamil Samigullin, Isabelle Georg, Dr. Michael Bolte, Dr. Hans-Wolfram Lerner and Prof. Dr. Matthias Wagner

A Highly Reactive Geminal P/B Frustrated Lewis Pair: Expanding the Scope to C−X (X=Cl, Br) Bond Activation

Complementary twins: The geminal frustrated Lewis pair tBu2PCH2B[3,5-(CF3)2C6H3]2 (1) is accessible from tBu2PCH2Li and [3,5-(CF3)2C6H3]2BF. Compound 1 readily activates element–element single, double, and triple bonds. Remarkably, CX4 undergoes C−X bond heterolysis with formation of unprecedented XP/BCX3 adducts (X=Cl, Br; see scheme).

Construction of a 2D Graphene-Like MoS2/C3N4 Heterojunction with Enhanced Visible-Light Photocatalytic Activity and Photoelectrochemical Activity

Construction of a 2D Graphene-Like MoS2/C3N4 Heterojunction with Enhanced Visible-Light Photocatalytic Activity and Photoelectrochemical Activity

MoS2/C3N4 heterojunction: A new type of graphene-like MoS2/C3N4 composite has been prepared by a facile ethylene glycol-assisted solvothermal treatment. The synergistic effect of face-to-face combination increases the contact area and makes charge transfer more efficient, thereby promoting the separation of electron–hole pairs and leading to an enhancement of the overall photoconversion efficiency (see picture).

Design and Syntheses of Three Novel Carbonate Halides: Cs3Pb2(CO3)3I, KBa2(CO3)2F and RbBa2(CO3)2F

Design and Syntheses of Three Novel Carbonate Halides: Cs3Pb2(CO3)3I, KBa2(CO3)2F and RbBa2(CO3)2F

Hello halide! Three novel carbonate halides, Cs3Pb2(CO3)3I (CPCI), KBa2(CO3)2F (KBCF) and RbBa2(CO3)2F (RBCF), have been synthesized through hydrothermal and solid-state methods (see figure). Cs3Pb2(CO3)3I, the first product in the lead carbonate iodide family, displays a moderate birefringence; KBa2(CO3)2F and RbBa2(CO3)2F are the first two centrosymmetric compounds found in the alkaline–alkaline earth carbonate fluorides.

Point-to-Plane Nonhomogeneous Electric-Field-Induced Simultaneous Formation of Giant Unilamellar Vesicles (GUVs) and Lipid Tubes

Chuntao Zhu, Ying Zhang, Yinan Wang, Qingchuan Li, Dr. Wei Mu and Prof. Dr. Xiaojun Han

Point-to-Plane Nonhomogeneous Electric-Field-Induced Simultaneous Formation of Giant Unilamellar Vesicles (GUVs) and Lipid Tubes

Simultaneous formation of giant unilamellar vesicles (GUVs) and lipid tubes using a nonhomogeneous electric field generated by point-to-plane electrodes is reported. The figure shows a fluorescence image of the products under an AC field of 2.5 V and 10 Hz with an electrode distance of 340 μm (top) and the side view of the GUV electroformation setup (bottom).

Activity Enhancement of G-Quadruplex/Hemin DNAzyme by Flanking d(CCC)

G-quadruplex/hemin DNAzymes: d(CCC)-containing sequences flanking on parallel G-quadruplexes improve the hemin binding affinity to G-quadruplexes and result in the enhancement of the DNAzyme activity and hemin degradation, as well as increase the tolerance of DNAzymes to pH change (see figure).

Stereodivergent Synthesis and Stereochemical Reassignment of the C79–C104 Fragment of Symbiodinolide

Structural revision: Stereodivergent synthesis of eight possible diastereoisomers that correspond to the C79–C97 and C94–C104 fragments of symbiodinolide has been carried out, which resulted in the proposal of two candidate stereostructures, respectively. Subsequently, the synthesis of the four possible diastereoisomers of the C79–C104 fragment and comparison of their 13C NMR data with those of the natural product has allowed stereostructural revision of this fragment of symbiodinolide (see figure).
