Dissociative Electron Transfer to Diphenyl-Substituted Bicyclic Endoperoxides: The Effect of Molecular Structure on the Reactivity of Distonic Radical Anions and Determination of Thermochemical Parameters

Autor: David C. Magri, Mark S. Workentin

Publikováno v: Molecules, Vol 19, Iss 8, Pp 11999-12010 (2014)

The heterogeneous electron transfer reduction of the bicyclic endoperoxide 1,4-diphenyl-2,3-dioxabicyclo[2.2.1]hept-5-ene (4) was investigated in N,N-dimethylformamide at a glassy carbon electrode. The endoperoxide reacts by a concerted dissociative

Towards the design of self-sorting nanomaterials through kinetically directed chemoselective control over interfacial surface chemistry

Autor: Praveen N. Gunawardene, Max Weissman, Jack E. Bowman, Pierangelo Gobbo, Mark S. Workentin

Publikováno v: Journal of Materials Chemistry B. 11:4661-4665

Gold nanoparticles can be selectively modified post-synthesis using kinetically tunable strain-promoted azide-alkyne (SPAAC) or azide-nitrone (SPANC) cycloaddition interfacial chemistry providing kinetically-directed strategies for self-sorting.

Colloidosomes as a Protocell Model: Engineering Life‐Like Behaviour through Organic Chemistry

Autor: Jun Hyeong Park, Agostino Galanti, India Ayling, Sebastien Rochat, Mark S. Workentin, Pierangelo Gobbo

Publikováno v: European Journal of Organic Chemistry. 2022

The bottom-up synthesis of self-assembled micro-compartmentalised systems that mimic basic characteristics of living cells is rapidly evolving. These types of systems are termed “protocells” and can be chemically programmed to grow and divide, to

Strained alkyne polymers capable of SPAAC via ring-opening metathesis polymerization

Autor: Rajeshwar Vasdev, Kyle Classen, Joe B. Gilroy, Wilson Luo, Mark S. Workentin, Michael Anghel, Samantha Novoa

Publikováno v: Polymer Chemistry. 12:5542-5547

The incorporation of strained alkynes into polymers is generally achieved by employing step-growth polymerization methods or post-polymerization reactions. Here, we demonstrate that cyclopropenone-masked strained alkynes are tolerant to chain-growth

Golden Opportunity: A Clickable Azide-Functionalized [Au25(SR)18]− Nanocluster Platform for Interfacial Surface Modifications

Autor: John F. Corrigan, Praveen N. Gunawardene, Mark S. Workentin

Publikováno v: Journal of the American Chemical Society. 141:11781-11785

Ultrasmall atomically precise monolayer-protected gold thiolate nanoclusters are an intensely researched nanomaterial framework, but there is a lack of a system that can be directly synthesized and...

Highly Electron-Deficient Pyridinium-Nitrones for Rapid and Tunable Inverse-Electron-Demand Strain-Promoted Alkyne-Nitrone Cycloaddition

Autor: Wilson Luo, Alexander M. Polgar, Mark S. Workentin, Praveen N. Gunawardene, John F. Corrigan

Publikováno v: Organic Letters. 21:5547-5551

Highly accelerated inverse-electron-demand strain-promoted alkyne-nitrone cycloaddition (IED SPANC) between a stable cyclooctyne (bicyclo[6.1.0]nonyne (BCN)) and nitrones delocalized into a Cα-pyridinium functionality is reported, with the most elec
