10 December 2021: Matthew's paper on the synthesis of polymer metal–organic frameworks (polyMOFs) using reversible addition fragmentation chain transfer (RAFT) polymerization and free radical polymerization (FRP) is publishd online in Chemistry of Materials. This work represents the first use of radical polymerization to form polymeric ligands for polyMOFs, opening the door to a wide range of new polyMOF compositions. Additionally, Matthew found that polymer ligand dispersity plays a key role in polyMOF crystallinity, with higher dispersity FRP-based polymers more readily forming crystalline polyMOFs than lower dispersity RAFT-based polymers. This result provides a new design principle for polyMOF synthesis, allowing rational tuning of ligand composition to balance material properties in the future.

25 November 2021: Happy Thanksgiving! Our paper initiated by former postdoc Jonathan and ultimately led by former group members Hung and Yivan describing the synthesis and biological investigation of bottlebrush polymers with discrete, chiral side chains appears online today in Nature Chemistry! In this work, we developed a new iterative exponential growth (IEG) strategy for the synthesis of discrete macromonomers with precise absolute configurations and tunable conformational rigidities. Two pairs of enantiomeric macromonomers were prepared and subjected to ROMP to produce bottlebrush polymers with mirror-image sidechains. Remarkably, we found that bottlebrush polymers with conformationally flexible side chains displayed handedness-dependent biological properties in vitro and in vivo, whereas comparably rigid bottlebrushes did not. These finding were rationalized using a simple model of chiral objects interacting with a chiral wall, showing that when the lock-and-key model does not apply, conformational flexibility can enhance chiral recognition. Thanks to all of our former group members (Hung, Yivan, Jonathan, Nate, Kathleen, Qixian, Matt, and Katherine!), current student Wencong, and our collaborators Rafael Gómez-Bombarelli, Adam Willard, Mike Hore, and their group members for their excellent contributions to this work! It has been years in the making! Click on the image below to read the paper.

10 August 2021: Manu and Yivan's paper on the efficient synthesis of discrete glycomacromolecules—"glyco-IEGmers"—published online in JACS Au. Here, Manu and Yivan used iterative exponential growth (IEG) to prepare mannosylated oligotriazoles of varying lengths, absolute configurations, and topologies. Working in collaboration with Prof. Remzi Becer, we studied the binding of these molecules toward 8 different human lectins, showing that their molecular features can give rise to several orders-of-magnitude variations in binding affinity and selectivity. Then, with Prof. Laura Kiessling, we showed that their cellular trafficking can be tuned by altering their sidechain composition. All of these results were supported by molecular dynamics simulations from Prof. Rafael Gómez-Bombarelli, which revealed that the stereochemistry of the glyco-IEGmer backbone impacts its conformational diversity, which in term affects lectin binding. Congrats to everyone involved in this great work! Click on the image below to read the open access paper.

26 March 2018: Nolan's paper describing a new class of main-chain-zwitterionic supramolecular polymers, called poly(azolium amidinate)s or "PAzAms," published online in Macromolecules. These fascinating new polymers are derived from the formation of N-heterocyclic carbene (NHC)-carbodiimide (CDI) adducts. Nolan shows that it is possible to finely tune the (thermo)dynamics of pZAms to enable their controlled depolymerization and morphing between different PAzAm structures. Congrats Nolan! Click on the image below to read the paper.

26 March 2018: Collaborative paper with the Shao-Horn group (MIT Mechanical Engineering) and Samsung Advanced Institute of Technology (SAIT) on the design of modular salts for battery applications published online in Energy and Environmental Science. In this work, we sought to expand the structural scope of sulfonimides, which are common components of lithium and other batteries. The famous TFSI anion is frequently used in batteries thanks to its excellent stability, but it cannot be easily chemically modified to alter its properties such as solubility and size. In this paper, we develop a new family of sulfonimides called Fluorinated Aryl Sulfonimide Tagged ("FAST") anions that can be rapidly and easily modified to generate metal salts with tunable properties. FAST salts greatly expand the number of available Li or other metal salts available for use in battery research. Congrats to the whole team, especially Mingjun and Shuting, for this great effort! Click on the image below to read the paper.

26 March 2018: Hung's paper on a scalable synthetic strategy for multivalent macromonomers is published online in ACS Macro Letters.

In addition, it allows us to easily incorporate multiple functionalities onto the same macromonomer, which is a gamechanger for our projects on drug delivery and imaging with bottlebrush and brush-arm star polymers. Congrats Hung! Click on the image below to read the paper.

Prior to this work, it was only possible to measure primary loop defects. As we continue to investigate the impact of topological defects in polymer networks, Junpeng's "NDS2.0" will be an invaluable tool. Congrats to Junpeng and the rest of the group for this great work!

Congrats to Matt, Yivan, and the rest of the group for this great work! Click on the image below to read the paper.

17 January 2018: Collaborative paper with the Olsen group (MIT Chemical Engineering) on the topological structure of TetraPEG gels appears online in Macromolecules. In this paper, we developed kinetic graph theory and Monte Carlo simulations that allow for the study of cyclic topologies in A_4 + B_4 polymer networks. These studies confirm that secondary loops, wherein two strands link two adjacent junctions, play a particularly fundamental role in the properties of these ubiquitous materials. Congrats to Tzyy-Shyang and Rui for yet another great work! Click on the image below to read the paper.

18 December 2017: The group welcomes new visiting student Shuto Mochizuki and visiting professor Prof. Masahiro Fujita.

5 December 2017: Collaborative paper with the Olsen group (MIT Chemical Engineering) on quantifying the gel point in end-linked polymer networks appears online in ACS Macro Letters.
