A tunable cohesive granular material
Ref.-Nr.: 0705-5158-BC
Neue Materialien
For sieving and separation purposes porous materials with adjustable sizes and shapes of the pores as well as tunable mechanical properties are required. The existing materials such as sintered materials, open-cell foams or cemented aggregates can be made porous but they are either fragile or can collapse for large deformation. Therefore, chemically inert and damage resistant porous materials with adjustable permeability as well as mechanical and geometrical properties that can sustain large deformation ...
Anti-mouse and anti-rabbit IgG secondary VHH single domain antibodies optimized for all immuno-labeling applications
Ref.-Nr.: 0707-5419-LI
Neue Materialien
Anti-IgG secondary antibodies are major tools for the detection or immobilization of primary antibodies in approaches such as western blotting, ELISA, Co-IP and immunofluorescence. Polyclonal anti-IgG secondary antibodies are produced in animals, such as mouse, rabbit, rat, and goat and are directed against the IgG classes of these animals. Thus, the generation of such secondary antibodies requires the keeping and use of a large number of animals, which is not only costly but also a major ethical ...
Cell-Penetrating Fluorescent Dyes with Secondary Alcohol Functionalities
Ref.-Nr.: 0707-5236-BC
Bildgebung und Mikroskopie
Neue Materialien
Fluorescent dyes are widely used as indispensable markers in biology, optical microscopy, and analytical chemistry. The availability and the proper choice of the dye is a key factor to success of the entire labelling and imaging procedure. Due to superior brightness and photostability, synthetic dyes often represent an attractive alternative to fluorescent proteins.
Among the multitude of fluorophores reported so far, only rhodamines, carbopyronines, and silicon-rhodamines bearing a carboxyl ...

Cyclopropenylylidene-Stabilized Phosphenium Cations and their Applications in Homogeneous Catalysis
Ref.-Nr.: 0042-5177-LC-WA
Prozesse und Methoden (inkl. Screening) : Chemische
Forschungs-Reagenzien : Andere
Neue Materialien
We offer novel phosphenium ligands and corresponding metal complexes (both air stable) that are claimed as substances by granted EP and US patents. The ligands can be prepared in multigram scale by simple direct condensation. The corresponding gold complexes are suitable as homogeneous catalysts in organic synthesis (such as cycloisomerization) that can be easily precipitated and recycled due to their salt properties.
N-substituted pyridiniophosphines, processes for their preparation and their use
Ref.-Nr.: 0042-4938-LC-WA
Prozesse und Methoden (inkl. Screening) : Chemische
Forschungs-Reagenzien : Andere
Neue Materialien
We offer a new family of cationic ligands, namely N-alkyl/aryl pyridiniophosphines. The ligands can be synthesized through a short, scalable, and highly modular route.
Evaluation of their electronic properties evidenced weak σ-donor and quite strong π-acceptor character when used as ancillary ligands.

Nanographene-based dyes as high performance probes for super-resolution microscopy

Analytik
Bildgebung und Mikroskopie
Neue Materialien
Super-resolution microscopy critically relies on the availability of appropriate fluorophores. For single-molecule localization microscopy (SMLM), fluorophores are needed that stochastically switch between bright (on) and dark (off) states. This phenomenon is also called fluorescence blinking. For stimulated emission depletion microscopy (STED) the dyes must be photo-switchable.

Organotextile Catalysis
Ref.-Nr.: 0042-4764-LC-WA
Prozesse und Methoden (inkl. Screening) : Chemische
Neue Materialien
An easy process for the facile and permanent immobilization of organocatalysts on nylon textiles was developed.
All of the prepared textile-immobilized organocatalysts (a Lewis basic, a Brønsted acidic, and a chiral organocatalyst) display excellent stability, activity and recyclability for various organic transformations. Very good enantioselectivity (>95:5 enantiomeric ratio) can be maintained for more than 250 cycles of asymmetric catalysis. The flexible construction of fabrics allows ...
Superamphiphobic membranes for gas exchange and scrubbing
Ref.-Nr.: 0903-4616-LC
Neue Materialien
Novel gas exchange membranes based on superamphiphobic coatings applied on metal meshes were created and tested in different applications, like gas scrubbing and blood oxygenation.
By using the novel membrans drawbacks of traditional membranes - like insufficient wetting, plugging and depositions chemical incompatibility and temperature instability - can be avoided.

Thioimidazolium ionic liquids as non-volatile and derivatizable alkylating reagents
Ref.-Nr.: 0401-5411-LC-WA
Prozesse und Methoden (inkl. Screening) : Chemische
Forschungs-Reagenzien : Andere
Neue Materialien
The offered thioimidazolium ionic liquids are a class of easily synthesized and harnessed alkylating agents that are completely non-volatile. The active alkylating species is produced in-situ, thus eliminating exposure and the need for specialized equipment. These features can also be used in the solid-state by their attachment to a poly(styrene) support, which allows for easy purification of the product and regeneration of the thioimidazolium alkylator and could be of special interest for flow ...
