Formamides as Isocyanate Surrogates: A Mechanistically-Driven Approach to the Development of Atom-Efficient, Selective Catalytic Syntheses of Ureas, Carbamates and Heterocycles.

open access: yesJournal of the American Chemical Society, 2019
Despite the hazardous nature of isocyanates, they remain key building blocks in bulk and fine chemical synthesis. By surrogating them with less potent and readily available formamide precursors, we herein demonstrate an alternative, mechanistic approach ...

Beyond Cartilage‐Inspired Supramolecular Polyurethane for Adaptive Impact‐Resistant Protection with Robustness, Self‐Healing, and Recyclability

open access: yesAdvanced Science, EarlyView.
Cartilage‐inspired supramolecular polyurethane–urea (PU‐BAMB) elastomers are developed by integrating hierarchical hydrogen bonding and π–π stacking interactions within a dynamically reconfigurable network. This synergistic supramolecular architecture overcomes the intrinsic trade‐off between rigidity and recoverability, imparting exceptional toughness,

Developing an Efficient and General Strategy for Immobilization of Small Molecules onto Microarrays Using Isocyanate Chemistry

open access: yesSensors, 2016
Small-molecule microarray (SMM) is an effective platform for identifying lead compounds from large collections of small molecules in drug discovery, and efficient immobilization of molecular compounds is a pre-requisite for the success of such a platform.

Dynamic Supramolecular Polyurethane Elastomers Enabling Bioinspired Strain‐Adaptive Stiffening to Resolve the Softness–Strength Paradox

open access: yesAdvanced Science, EarlyView.
Segmental‐level molecular engineering of a supramolecular polyurethane elastomer integrates strain‐adaptive chains, soft elastic segments, and dynamic hydrogen bonding motifs. This design reconciles skin‐like softness with muscle‐level strength, offering a sustainable and high‐performance material platform for next‐generation artificial skin and soft ...
