  • Process for the preparation of tetracarboxynaphthalenediimide compounds disubstituted with heteroaryl groups
    Patent number: 9000170
    Abstract: A process for the preparation of a tetracarboxynaphthalenediimide compound disubstituted with heteroaryl groups having general formula (I), comprising the reaction of at least one disubstituted N,N?-dialkyl-1,5,8-tetracarboxynaphthalenediimide with at least one heteroaryl compound. Said tetracarboxynaphthalenediimide compound disubstituted with heteroaryl groups can be advantageously used as monomer in the synthesis of semiconductor polymers which can be advantageously used in the construction of organic field effect transistors (OFET) or of organic thin film transistors (OTFT).
    Type: Grant
    Filed: March 18, 2013
    Date of Patent: April 7, 2015
    Assignee: ENI S.p.A.
    Inventors: Guiliana Schimperna, Andrea Pellegrino, Stefano Chiaberge, Gabriele Bianchi
  • PROCESS FOR THE PREPARATION OF TETRACARBOXYNAPHTHALENEDIIMIDE COMPOUNDS DISUBSTITUTED WITH HETEROARYL GROUPS
    Publication number: 20150051398
    Abstract: A process for the preparation of a tetracarboxynaphthalenediimide compound disubstituted with heteroaryl groups having general formula (I), comprising the reaction of at least one disubstituted N,NI-dialkyl-1,4,5,8-tetracarboxynaphthalenediimide with at least one heteroaryl compound. Said tetracarboxynaphthalenediimide compound disubstituted with heteroaryl groups can be advantageously used as monomer in the synthesis of semiconductor polymers which can be advantageously used in the construction of organic field effect transistors (OFET) or of organic thin film transistors (OTFT).
