A hyperbranched porous polymer P based on adamantane and pyrene was synthesized through the Sonogashira coupling reaction. The quenching efficiency (ηEP) of film P in saturated DNT vapour reached 82% due to its 3D structure.
The highest efficient red-to-green upconversion is achieved in a TTA-UC pair consisted of PdTPTBP and pyrene derivative via molecular engineering. This pair is successfully used to activate photooxidation of aryl boronic acid under red light, and the reaction yield is greatly improved compared to green light, showing the advantage of TTA-UC in photoredoxcatalysis.
