Synthetic Photoswitchable Neurotransmitters Based on Bridged Azobenzenes.
Organic Letters, 2019 Photoswitchable neurotransmitters of ionotropic kainate receptors were synthesized by tethering a glutamate moiety to disubstituted C2-bridged azobenzenes, which were prepared through a novel methodology that allows access to diazocines with higher ...

Synthesis of 4′-Alkoxy-4-(ω-cinnamoylalkoxy)azobenzenes and Their Photoswitchable Behavior
Chemistry Proceedings, 2021 In search of new thermotropic, photoswitchable materials, a number of 4′-alkoxy-4-(ω-cinnamoylalkoxy)azobenzenes were prepared. The synthetic procedure included O-alkylation of 4-nitrophenol, followed by reduction of the nitro group (H2, Pd/C ...

Deciphering Small Molecule Diffusion Parameters Across Light Responsive Polymersome Membranes
Advanced Functional Materials, EarlyView.Light‐responsive polymersomes bearing donor–acceptor Stenhouse adducts (DASAs) enable programmable control over small‐molecule transport across synthetic membranes. By systematically varying DASA density, an optimal functionalization regime is identified that maximizes light‐gated permeability.

X-ray-Induced Reversible Switching of an Azobenzene Derivative Adsorbed on Bi(111) [PDF]
, 2014 We report on the adsorption of a submonolayer of di-m-cyanoazobenzene (DMC) on Bi(111) and on the reversible switching of these molecules induced by resonant X-ray illumination.

Atomic Layer Deposition in Transistors and Monolithic 3D Integration
Advanced Functional Materials, EarlyView.Transistors are fundamental building blocks of modern electronics. This review summarizes recent progress in atomic layer deposition (ALD) for the synthesis of two‐dimensional (2D) metal oxides and transition‐metal dichalcogenides (TMDCs), with particular emphasis on their enabling role in monolithic three‐dimensional (M3D) integration for next ...
