EP22382566.2
This invention relates to a polymerization method, which exploits metal-catalyzed cross-coupling reactions, condensation reactions or free-radical reactions mediated by light within nanomicelles obtained by successive use of ultrasound tip conditions and microfluidic techniques to yield nanostructured conjugate porous polymers with reduced average particle size and narrow particle size dispersity. The invention also relates to the conjugate porous polymers obtainable by said method and hybrid organic-inorganic materials comprising said conjugate porous polymers as well as their application in the field of photocatalysis and in the production of thin films.
Advantages and Innovations: nanoCPPs shows processable properties which are not available for CPPs synthesized in bulk. At the same time, they show improved properties such as high micro- and mesoporosity, light harvesting, high conductivity, and great thermal, chemical and photo stability. The technology is very useful because it combines: - The process to synthetize different nanostructured Conjugated Porous Polymers, nanoCPPs, with properties that combine high micro- and mesoporosity, and great thermal, chemical and photo stability, as well as other properties that may be tailored such as light harvesting, conductivity, etc. - The different materials, nanoCPPs, with particular applications according to their chemical composition, structure and properties. In addition, nanoCPPs can be processed in liquid phase applying them in thin layers or using plastic technologies such as extrusion, injection, etc. Both CPPs and nanoCPPs can be used for a wide range of applications, including gas storage, catalysis and optoelectronics, due to their remarkable properties such as high micro- and mesoporosity, light harvesting, high conductivity, and great thermal, chemical and photo stability.
