Synthesis of M13 clusters from aluminum and gallium mineral polymorphs

A method for detecting for the presence of HS or HSanion in a system, comprising contacting a sample from the system with a compound, or a protonate or salt thereof, having a structure represented by: 

Synthetic receptors for hydrosulfide

A compound, or a protonate or salt thereof, of formula I:  is an aryl or heteroaryl ring; and are not respectively.

Fluorescent halogen bonding arylethynyl scaffolds for anion recognition

Disclosed embodiments concern a phosphorus-containing heterocyclic compound according to the formula One exemplary compound is Certain embodiments fluoresce with excitation by light. The compounds are useful as fluorescent probes and as bioisosteres. In some embodiments, the compounds are bioisosteres of alpha-quinolones. Also disclosed is a method for making the compounds.

Phosphorus-containing heterocycles and a method for making and using

Disclosed herein is a novel method for preparing cyclophanes, comprising forming a disulfide cyclophane by contacting a linker moiety which includes two or more thiol groups, with a metal salt and an oxidant. The disulfide cyclophane is then desulfurized to form a thiacyclophane comprising thioether bridges. This thiacyclophane optionally may be further desulfurized to form an unsaturated hydrocarbon cyclophane, which can then be reduced to form a saturated hydrocarbon cyclophane. The various cyclophanes can be synthesized in a ring form, such as a dimer, trimer or tetramer etc., or they can be synthesized in a tetrahedral or larger structure. Also disclosed are novel cyclophanes formed by the disclosed method.

Synthesis of cyclophanes for a self-assembly reaction

Disclosed herein is a material comprising a functionalized solid support surface, wherein the functionalization comprises a thioalkylene linker bound to the support surface and the thioalkylene linker is coupled to a moiety derived from a ligand, wherein the ligand includes a terminal alkenyl and at least one first functional group configured to bind to at least one predetermined target species.

Phenylacetylenes

Synthesis of cyclophanes from a self-assembly reaction

A compound, or a salt thereof, having the formula  

Tunable phenylacetylene hosts

Metallic clusters can be produced by contacting a metal salt such as a metal nitrate with an organic reducing agent. Metals can be selected from a group consisting of metals exhibiting octahedral coordination, and nitrates of the selected metal or metals are contacted with, for example nitrosobenzene. Binary, tertiary, or other clusters can be produced.

Methods for producing gallium and other oxo/hydroxo-bridged metal aquo clusters

Disclosed herein is a class of tunable phenylacetylene compounds as well as compositions and methods for their use as host compounds for ligand binding. In certain examples the hosts report binding events by exhibiting altered spectroscopic properties, such as different fluorescent emission spectra.

A method, article of manufacture and apparatus are disclosed for binding successive layers of a 'guest specie' such as an atom, cation, anion, organic molecule, and/or pathogen to a substrate or multiple different substrates. Possible substrates include materials with a porous nature; macro, micro and nano porous materials are all candidates. The adsorbent capacity of a substrate is extended by coordinating a layer of bi- or multi-functional ligand (L) to an adsorbed atom or ion or molecule or pathogen, which is then coordinate to a second layer of adsorbed atom or ion or molecule or pathogen.
