  • METHOD FOR OBTAINING FUNCTIONALIZED POLYMERIC SURFACES WITH PHOTOSENSITIZERS, FUNCTIONALIZED POLYMERIC MATERIAL AND USE THEREOF
    Publication number: 20220259334
    Abstract: The present invention describes methods for obtaining functionalized polymeric surfaces (MPn-PSm) from polymers or copolymers with appropriate functionalizations (X), which can be a halogen of a leaving group, such as polyvinyl chloride (MP1) and (chloromethyl)polystyrene-Merrifield (MP2), and curcumin photosensitizers (PS1), meso-tetra(aryl)porphyrins, chlorins or bacteriochlorins halogenated and functionalized with nucleophilic groups (PS2), in particular including P2 of the type meso-imidazoyl-porphyrins, chlorins or bacteriochlorins (PS3). The structures of all the photosensitizers in the present application incorporate a functional group (Y), which is a OH, SH or NH2nucleophile. The application also describes the covalent bonding process of the photosensitizers PS1-PS3 to the functional polymeric materials MP1-MP2 by means of a nucleophilic substitution reaction to prepare the MPn-Psm products.
