  • Polymorph, polymorph screening system, and polymorph preparing and screening method
    Patent number: 8865093
    Abstract: A polymorph, a polymorph screening system, and a polymorph preparing and screening method are disclosed. The polymorph preparing and screening method includes the following steps: providing a plurality of substrates of different materials; causing an organic material to grow crystals on the plurality of substrates through solution-cooling crystallization process, so that a plurality of polymorphs with different characteristics are prepared; and screening the plurality of polymorphs prepared in the previous step to obtain polymorphs with desired characteristics.
    Type: Grant
    Filed: October 20, 2011
    Date of Patent: October 21, 2014
    Assignee: National Central University
    Inventors: Tu Lee, Shih-Chia Chang, Jen-Fan Peng, Pu-Yun Wang, Yu-Kun Lin
  • Co-crystal compound of optical device
    Patent number: 8653267
    Abstract: The present invention discloses a co-crystal compound of optical devices. The co-crystal compound is crystallized out with hydrogen bonding by a temperature fluctuation method after mixing small organic molecules without optoelectronic properties and organic molecules having heterocyclic rings with optoelectronic properties. The photoluminescence (PL) intensity of this hydrogen-bonded co-crystal compound according to the present invention can vary with a variety of the small organic molecules without optoelectronic properties, so as to modulate the PL intensity.
