Process for the hydroformylation of olefins using a cobalt pre-catalyst.

A coordination compound, and a light absorber including the same.

The present invention relates to means and methods for conjugating/attaching target molecules such as proteins to a label and/or carrier. Specifically, the present invention provides a complex comprising a metal cation coordinating (i) nitrate as a metal cation ligand and (ii) a metal cation chelating domain comprising a chelating ligand and a label and/or carrier. This complex can be used for attaching a label and/or a carrier to a target molecule, preferably a protein. The attachment of the label or carrier via the complex of the invention involves the replacement of the metal cation ligand with a coordinating group of the target molecule so that a product complex with the target molecule as primary ligand in the coordination sphere of the metal cation is formed. Accordingly, the present invention also provides for uses and methods involving the attachment of a label and/or carrier to a target molecule. Also provided are the products obtained by the labeling and or carrier-attaching methods of the invention and uses thereof. The invention further relates to methods for producing the complex of the invention and kits comprising the components for producing the complex of the invention.

Described herein are cobalt compounds, processes for making cobalt compounds, cobalt compounds used as precursors for depositing cobalt-containing films (e.g., cobalt, cobalt oxide, cobalt nitride, cobalt silicide etc.); and cobalt films. Examples of cobalt precursor compounds are bis(diazadiene)cobalt compounds. Examples of surfaces for deposition of metal-containing films include, but are not limited to, metals, metal oxides, metal nitrides, and metal silicates; silicon, silicon oxide and silicon nitride. Alkylated diazadiene ligands are used to form cobalt complexes which are used for selective deposition on certain surfaces and/or superior film properties such as uniformity, continuity, and low resistance.

A confined porphyrin Co(II), which is prepared by the following method: Equimolar amounts of aromatic aldehyde and pyrrole are condensed under acidic conditions to synthesize phenyl porphyrin compounds; the phenyl porphyrin compounds are metallized in a chloroform-methanol solution to obtain porphyrin Cu(II), which is brominated and demetallized to obtain confined porphyrin; the confined porphyrin is stirred and refluxed in a methanol solution for 12.0-24.0 h to obtain confined porphyrin Co(II). Its application is as follows: The confined porphyrin Co(II) is dissolved in cycloalkanes; the reaction system is sealed, and heated to 100 to 130° C. with stirring, to which oxygen is introduced to 0.2 to 3.0 MPa; the reaction is carried out for 3.0 to 24.0 h with stirring with the set temperature and oxygen pressure being maintained; and then the reaction solution is subjected to post-treatment to obtain the products.

Provided herein are dyes, dye-sensitized solar cells, and sequential series multijunction dye-sensitized solar cell devices.

Mixed metal metal-organic frameworks (MM-MOFs) of copper-1,3,5-benzenetricarboxylate (BTC), M—Cu-BTC, wherein M is Zn(II), Ni(II), Co(II), and/or Fe(II) may be made using post-synthetic exchange (PSE) with metal ions. Such MM-MOFs may be used in H.sub.2 storage, especially Ni(II) and Co(II) MM-MOFs. Selected metal exchanged materials can provide gravimetric H.sub.2 uptake around 1.63 wt. % for Zn—Cu-BTC, around 1.61 wt. % for Ni—Cu-BTC, around 1.63 wt. % for Fe—Cu-BTC, and around 1.12 wt. % for Co—Cu-BTC.

The present invention discloses a Double Metal Cyanide (DMC) catalyst(s) useful for the production of polyether polyols (PEPO) and a less energy intensive room temperature method for the synthesis thereof. The catalyst(s) comprises of a DMC complex, an organic complexing agent, i.e., ethylenediaminetetraacetic acid (EDTA) and other co-complexing organic agents, e.g., t-BuOH, PEPO of composition ranging from about 1 to 10 wt %, wherein the average molecular weight of PEPO used ranged from 200 to 1000. A method of preparing a series of DMC catalyst(s) at room temperature with varying compositional ratios of the complexing and co-complexing agents targeting a wide range of PEPO of varying kinematic viscosity range is also disclosed. These DMC catalyst(s) are amorphous, highly active, and easily separable from product PEPO with recyclability/recoverability, making the product PEPO better industrially applicable and DMC catalyst more cost-effective.
