  • Method for detecting mechanoresponse of mechanical component by organic mechanoresponsive luminogen
    Patent number: 11275002
    Abstract: The present invention discloses a method for detecting the mechanical response of a mechanical component by an organic mechanoresponsive fluorescent material, comprising the following steps of: selecting an organic mechanoresponsive fluorescent material; preparing an organic mechanoresponsive fluorescent material solution; forming a film on a metal surface; calibrating fluorescence intensity and obtaining the fluorescence intensity and distribution in a crack tip area; observing the fluorescence signal generated at cracks to monitor the occurrence of fatigue cracks, and predict a propagation pathway of fatigue cracks by using the fluorescence intensity distribution in the crack tip area.

  • Polymer poly (triphenylacrylonitrite) and synthesis thereof
    Patent number: 10941243
    Abstract: A method is directed to synthesis of poly(triphenylacrylonitrite)s (PTPANs) comprising polycoupling dibromoarenes, internal diynes, and potassium ferrocyanide, resulting in polycoupled dibromoarenes, internal diynes, and potassium ferrocyanide; and producing poly(triphenylacrylonitrite)s (PTPANs) by catalysis of the polycoupled dibromoarenes, internal diynes, and potassium ferrocyanide with palladium acetate and sodium bicarbonate, wherein the catalysis is allowed to proceed in dimethylacetamide under nitrogen at a prescribed temperature for a prescribed time.
