A vinylogous Norrish reaction as a strategy for light-mediated ring expansion

Evgueni Gorobets, James W. Papatzimas, Jorge Dourado, Goonay Yousefalizadeh et autres

The reactions of bicyclic divinyl ketones display wavelength-dependent changes in product formation. UV irradiation results in the formation of competitive [6,3,5] and [7,3,5] tricyclic unsaturated ketones that subsequently undergo ring expansion and reaction with a range of nucleophiles. DFT calculations and transient …

Photophysics of Ag and Au alloys of M25(SR)18 clusters

Goonay Yousefalizadeh, Kevin G. Stamplecoskie

Superatom clusters, Au25(SR)18, and the silver analog and alloys of the two metals have been extensively investigated for their structure, stability, photoluminescence, and electronic properties. One can readily tune the physicochemical properties by varying the ratio of Au/Ag or the thiol ligand …

Atomically Precise Metal Clusters: Synthesis, Excited State Dynamics, and Unique Optical Properties

Goonay Yousefalizadeh

Metal clusters are small particles with the exact number of metal atoms and the number/type of ligand molecules bound to the surface. The optical and electronic properties of these materials can be tuned and controlled with precise synthesis. These materials exhibit phenomena …

Photophysics of J-Aggregating Porphyrin-Lipid Photosensitizers in Liposomes: Impact of Lipid Saturation

Danielle M. Charron, Goonay Yousefalizadeh, Hilde Harb Buzzá, Maneesha A. Rajora et autres

Porphyrin aggregates have attractive photophysical properties for phototherapy and optical imaging, including quenched photosensitization, efficient photothermal conversion, and unique absorption spectra. Although hydrophobic porphyrin photosensitizers have long been encapsulated into liposomes for drug delivery, little is known about the membrane properties of …

Robust, Highly Luminescent Au 13 Superatoms Protected by N-Heterocyclic Carbenes

Mina R. Narouz, Shinjiro Takano, Paul A. Lummis, Tetyana I. Levchenko et autres

Gold superatom nanoclusters stabilized entirely by N-heterocyclic carbenes (NHCs) and halides are reported. The reduction of well-defined NHC–Au–Cl complexes produces clusters comprised of an icosahedral Au 13 core surrounded by a symmetrical arrangement of nine NHCs and three chlorides. X-ray crystallography shows …
