Controlled Aggregation of Pyrene‐Based Supramolecular Nanostructures for Light‐Driven Switchable H2 or H2O2 Production

Advanced Functional Materials, EarlyView.
This work reports the self‐assembly of a pyrene derivative into two distinct nanostructures and their application in visible‐light photocatalysis. The two nanostructures exhibit completely different yet complementary photocatalytic activities, promoting either H2 or H2O2 evolution.

Poly[[diaqua[μ2-3-carboxy-5-(pyridine-4-carboxamido)benzoato][μ4-5-(pyridine-4-carboxamido)isophthalato]cerium(III)] monohydrate]

Acta Crystallographica Section E, 2012
In the title compound, {[Ce(C14H9N2O5)(C14H8N2O5)(H2O)2]·H2O}n, three carboxyl groups of two independent isophthalate anions are deprotonated and they bridge the CeIII cations, forming a two-dimensional polymeric structure parallel to (001 ...

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

Biosynthesis of Amphotericin Derivatives Lacking Exocyclic Carboxyl Groups [PDF]

Journal of Biological Chemistry, 2005
Amphotericin B is a medically important antifungal antibiotic that is also active against human immunodeficiency virus, Leishmania parasites, and prion diseases. The therapeutic use of amphotericin B is restricted by severe side effects that can be moderated by liposomal formulation or structural alteration.

Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

Advanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

Carboxyl Group Reactivity in Actin [PDF]

, 1987
Actin is the principal protein of the thin filament of muscle and is also the major component of microfilaments. At low salt concentrations, actin exists in solution as a globular monomer (G-actin) of Mr=42,000. It has a single polypeptide chain of 375 residues and a bound metal-nucleotide (Mg++ or Ca++-ATP or ADP).
