We are enthusiastic about designing, creating, and playing with exotic small molecules and large polymers that are engineered for tailored properties.
Congratulations to Ben and Jessica! They finally cracked the secret code of cyclopropenes (it was once so mysterious!) and achieved controlled single addition of cyclopropenes at any desired locations along a living ROMP polymer - See the story in Chem and highlight by C&EN. Let us know if you would like to try these cyclopropenes for your research!
4th PhD minted! Congratulations to Dr. Zexin Jin on his heroic efforts to develop the synthetic methodology, design aesthetically pleasing molecules, and understand the effects of CBD antiaromaticity! He is the only student in our group who doesn't work with polymers and established our project on CBD-containing polycyclic conjugated hydrocarbons from scratch.
We will miss you Dr. "Gin" -- wish you all the best for postdoc in the Nuckolls group!
Holden figured out the tricks to make very high MW (>300 KDa) CANAL ladder polymers, which formed nice membranes for gas separation, and discovered changing simple substituents can significantly increase permeability without compromising selectivity. The collaborative work with the Smith lab (MIT) was published in Macromolecules.
3rd PhD minted! Congratulations to Dr. Junzhe Lou, our group's polymer guru and 1st PhD in MSE! He's been a lone star and trailblazer in dynamic polymer networks and polyelectrolytes in our group, setting a role model on how to be exploratory, creative, meticulous, and truly interdisciplinary.
Junzhe also managed to win the People's Choice Award in the SPC poster symposium before heading to Harvard!
Benzoladderenes: Congrats to Jinghui and Matias on a new family of polymechanophores that transform from nonconjugated to conjugated polymers in response to force, reporting in JACS! Jinghui was also awarded the prestigious Stanford Graduate Fellowship!!
Two prestigious awards won by students!
Congratulations to Zexin for the Department William Johnson Award, which is awarded to one student per year to recognize outstanding academic and research achievements!
Congratulations to Matias for the NDSEG fellowship!
The group celebrated their awards with a tuxedo cake and an award dinner.
Thanks to the hard work from the past and present group members, Yan was awarded a Sloan Research Fellowship!
Congrats to Junzhe and Sean on using well-defined polyelectrolytes and rigorously measured phase diagrams to unambiguously reveal the effect of local polarity on coacervation, which was quantitatively captured by a simple model developed by the Qin group (Stanford), published in ACS Cent. Sci.
Congrats to Holden and Mahmoud on reporting CANAL ladder polyimides for membrane gas separation in Chem. Mater.! - our first paper on membrane gas separation in collaboration with the Pinnau group (KAUST).
We look forward to more exciting work from the fruitful collaborations!
Warm welcome to first year grad students Kayla Barker (Fang, TAMU) and Matias Horst (Franz, Duke) to officially join the group and Prof. Yu Zhao (NUS) for his sabbatical!
Congratulations to Yewchin on reporting a new method of synthesizing macromonomers and narrow-disperse brush block copolymers in Macromolecules and Zexin on reporting acene-like molecules containing strong antiaromaticiy with tunable electronics and packing in Angew Chem!
Warm welcome to our new postdoc Dr. Joe Ahn from the Fu and Peters groups at Caltech!
Congratulations to Jessica on the synthesis and mechanoactivation of the first mechanically responsive block copolymers in JACS and Zexin on a new member of naphthylene in Syn Lett as part of the cluster of Synthesis of Materials!
Interested in clean and quantitative end-functionalization of living ROMP polymers? Check out Ben's method using single-addition cyclopropenes. Let us know if you would like to try cyclopropenes for your next ROMP end-functionalization.
Yewchin's CBD-fused electron-poor phenazines published in Org. Lett. -- variable degrees of antiaromaticity strongly affect band gaps and optical properties.
Junzhe's trick to temporally modulate the injectability and stability of dynamic hydrogels using a biocompatible catalyst published in Adv. Mater.
The group welcomes new students JD (Caltech) and Jinghui (PKU)!
Wish Jing all the best for her faculty position at Wuhan University!
Congratulations to Zexin and Yewchin for their JACS paper on naphthylenes and tuning their antiaromaticity!
Congratulations to Zhixing Chen and the Stanford team for the awesome work featured on the cover of Science!
