Preparation of Co-porphyrin catalyst encapsulated in cyclodextrin-based metal-organic framework for coupling reaction

Immobilization of organometallic catalyst were attempted by using cyclodextrin-based metal-organic framework (CD-MOF) with the characteristic nanoporous structure. Water-soluble Co(II)TCPP was prepared as an and introduced into hydrophilic nanopores in CD-MOF co-crystallization method. In order to evaluate catalytic properties obtained Co(II)TCPP/CDMOF, oxidative coupling reaction creosol performed. At a concentration 0.2 mol%, activity heterogeneous Co(II)TCPP/CDMOF almost same that homogeneous catalyst. The conversion for Co(II)TCPP/CD-MOF reached 92% after 2-hour reaction.
