We are enthusiastic about designing, creating, and playing exotic small molecules and large polymers with unusual properties and behaviors.
Congratulations to Jinghui on publishing his work on a robust (almost) hydrocarbon polymer that can be transformed into acid-degradable polymer under mechanical stress!
Hearty welcome for 1st year student Francesca and Erica to officially join the group!
Congratulations to Jinghui and Dan for winning the prestigious :) 2020 Xia Group Awards!
Our journey with cyclopropene polymerization (and lack of) is summarized in Acc. Chem. Res: A Palette of Surprising Reactivity, created by artist Ben E.
Fluoro-ladderene to golden fluorinated polyacetylene published in Nat. Chem. Congratulations to Ben B and all members of the team!
Jinghui and Matias' benzoladderene 2019 paper was selected in the JACS Young Investigators issue!
A few days later, they report a new generation of mechanophore monomers in JACS! Multi-gram synthesis, various substituents to tune electroptical properties, ROMP all the way to DP=10000! and mechanically activated by rapid stirring of solution!
1) Welcome Dr. Dan Lee from UW and Dr. Xianglin Yin from Purdue to join the group!
2) Congrats to Jessica, SoYoung, and Ben on the study of ROMP of 1-Me-cyclopropenes in Macromolecules! Again, substituents strongly affect their reactivity. This papers concludes our 6-year campaign (for now) on discovering the surprising reactivities of various CPEs.
Congratulations to Dr. Holden Lai and Dr. Jessica Su, PhD#5 and 6 of our lab! First and hopefully only virtual defenses of our lab. Thank you for developing CANAL polymers into membranes for gas separation and taming the strained rings to advance polymer synthesis!
And thank you for being such fabulous lab citizens! You will be so missed.
Newly published: 1) general mechanism of CANAL; 2) air separation membranes from CANAL-TB ladder polymers in collaboration with Prof. Pinnau.
Our lab is temporarily closed amid the battle of human vs coronavirus. We stay intellectually active but shelter-in-place to help human win sooner!
Happy 2020 everyone! 3 papers out in the first month:
Cyclic enol ethers are effective ROMP monomers! Congrats to JD for this surprising discovery and development of depolymerizable and degradable poly(enol ether)s in JACS!
Our collaborative mechanistic study with the Martinez and Burns groups on the mechanochemistry of ladderane/ene is reported in Nat. Chem., revealing two significant dynamic effects: 1) cascade activation with rate acceleration; 2) bifurcation on potential energy surface determines product distribution. Congrats to Zhixing and the Stanford team!
Congrats to Ben and Jessica on using AROMP to synthesize degradable polyacetals in ACS Macro Lett!
Congrats to Holden on winning a NAMS student award to speak at the International Congress on Membranes in London!
