Partners sought for new metal-organic frameworks with application in gas storage and separation, membrane fillers, catalysis, lithium batteries, proton conductors, sensors, drug delivery systems etc.
A Czech research institute has developed and successfully prepared new hydrothermally stable metal-organic frameworks (MOFs). These metal-organic frameworks have application potential for gas storage and separation, membrane fillers, catalysis, lithium batteries, proton conductors, sensors, and drug delivery systems. The researchers are looking for partners interested in research or technical cooperation.
The researchers are looking for industry partners or research institutes which are skilled and experienced in development or applications of metal–organic frameworks MOFs. In the case of research cooperation agreement – a joint European project (e.g. Horizon 2020) cooperation is preferred. In the case of technical cooperation agreement - the aim of the cooperation is to jointly develop the new technology further and also get a summary of know-how, which could be subsequently a subject of commercialization. The cooperation should involve an experimental testing of the individual metal–organic frameworks (MOFs) systems on a more or less professional level using suitable technical equipment.
Metal–organic frameworks (MOFs) are coordination polymers consisting of metal ions or clusters coordinated to organic linker molecules forming ordered structures. Additionally, their structures have to contain potential voids in the structure. The problem up to now was that the size of the pores of the metal–organic frameworks (MOFs) could have been varied only by the size of the spacer between the coordinating groups and selection of the metal ions or clusters. This problem has been addressed by the Czech research institute focused on the research and development in the field of analytical methods, which offers metal–organic frameworks (MOFs) based on linkers containing phosphinic acid groups (in abbreviation R1R2POOH). The inorganic part of the structure is composed of tri-valent metal cations, mainly Fe(III), Al(III), or Y(III), that are connected via organic linkers containing at least two phosphinic acid groups (-PR1OOH) bound on a alkyl or aryl skeleton, e.g., 1.4-di substituted benzene, see the pictures below. The resulting structure is porous. The use of linker molecules bearing phosphinic acid groups solves the problem of fine tuning the pore size. Because pore size can be determined not only by the size of the linker molecule and metal ions or clusters, but also by the R1 groups bonded to P atom that can face inside the pore structure and therefore it can serve for partial pore blocking or can bear functional group in order to enhance the functional properties. Because of the strong coordination bond between the linker and the metal centres the resulting metal–organic frameworks (MOFs) structures display high hydrothermal stability which can be beneficial in applications where high humidity and temperature are applied or fluctuate. Therefore, the metal–organic frameworks (MOFs) offered have application potential for gas storage and separation (e.g. hydrogen and /or methane), membrane fillers, catalysis, lithium batteries, proton conductors, sensors, and drug delivery systems. Another application is biological imaging and sensing, bio-mimetic mineralization, carbon capture, desalination/ion separation. The researchers are looking for cooperation with an institution or a company with skills in development of new MOFs or finding application for MOFs. In the case of research cooperation agreement - cooperation based on a joint European project (e.g. Horizon 2020) is preferred. In the case of technical cooperation agreement - the aim of the cooperation is to get a survey of the possibilities of the new technology and to get summary know-how which could be subsequently a subject of commercialization. The cooperation should involve an experimental testing of the individual MOF systems.
Advantages and innovations
- High thermal stability up to 450°C on air and 500°C in Ar. - Hydrothermal stability: some of the MOFs can withstand boiling water for 24 hours without loss of porosity. - No solvents are coordinated to the MOF structure which saves energy- consuming activation process.

How it works
- Tell us about yourself
- We’ll discuss with you
- We put the right partners in touch
EEN help you find the right partner, rather than you going it alone.
Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.
These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.
Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
First we need to check you’re human.
