In this video abstract for http://MaterialsViews.com , Craig Hawker and Daniel Burke at the University of California Santa Barbara describe their paper "The power of thiol-ene chemistry", published in the Journal of Polymer Science: Part A, Polymer Chemistry (http://doi.wiley.com/10.1002/pola.23824 ). As a tribute to Professor Charlie Hoyle, the authors review the impact of thiol-ene chemistry on polymer and materials science over the past 5 years. During this time, a renaissance in thiol-ene chemistry has occurred with recent progress demonstrating its unique advantages when compared with traditional coupling and functionalization strategies. Additionally, the robust nature of thiol-ene chemistry allows for the preparation of well-defined materials with few structural limitations and synthetic requirements. To illustrate these features, the utility of thiol-ene reactions for network formation, polymer functionalization, dendrimer synthesis, and the decoration of three-dimensional objects is discussed. Also, the development of the closely related thiol-yne chemistry is described.
