Method for the design of highly efficient organic photoredox catalysts for visible-light-driven atom transfer radical polymerization

摘要

The present invention relates to a method of designing high-efficiency organic photoredox catalysts (OPC) for atomic transfer radical polymerization driven by visible light, and more specifically, to construct a twisted donor-acceptor. The conjugated low-molecular organic material is a candidate group for the organic photo-oxidation-reduction catalyst, and is based on efficient triplet exciton generation and strong intramolecular chrage transfer (CT) characteristics caused by structural factors. High efficiency to develop highly efficient organic photo-oxidation and reduction catalysts utilized in organocatalyzed atom transfer radical polymerization (O-ATRP) by providing a method to systematically control the properties of critical catalysts that have a decisive effect It relates to a method of designing an organic photo-oxidation-reduction catalyst. The organic photo-oxidation-reduction catalyst design method of the present invention provides a method for easily developing a high-efficiency organic photo-oxidation-reduction catalyst applied to an organic catalyst atom transfer radical polymerization, and can be carried out using a computer, thereby actually synthesizing the catalyst You can get very effective feedback without having to.
