Patents by Inventor Chih-Chia Cheng

Chih-Chia Cheng has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9391276
    Abstract: A conjugated polymer-based optoelectronic material includes: an optoelectronic conjugated polymer having a main chain and side chains; and an organic diluent which is at least partially miscible with the conjugated polymer. Molecules of the organic diluent physically react with the side chains of the conjugated polymer to form hydrogen bonds therebetween, thereby generating molecular constraints in the conjugated polymer to suppress molecular deformation of the conjugated polymer that occurs soon after the conjugated polymer is excited.
    Type: Grant
    Filed: November 19, 2014
    Date of Patent: July 12, 2016
    Assignee: NATIONAL TSING HUA UNIVERSITY
    Inventors: Arnold Chang-Mou Yang, Yen-Hui Liu, Chih-Chia Cheng, Cheng-Chung Huang

  • Patent number: 7863440
    Abstract: Disclosed are a macrocyclic carbodiimide (MC-CDI) and a process for synthesizing the same through condensation of a molecule with multiple-isocyanate terminal functional groups under high dilution in the presence of a phospholene catalyst such as phospholene or arsenic catalyst. Also disclosed are MC-CDI derivatives, such as MC-urea (MC-U), MC-acylurea (MC-ACU), acid functionalized MC-ACU, and anhydride functionalized MC-ACU, processes for synthesizing the same, and the applications of such derivatives as hydrolysis stabilizers in organic polymeric materials, such as polyurethane (PU) and polyesters, as well as the applications in the syntheses of the amide- and imide-modified polyurethane by ring-opening reaction of the MC-ACU.
