Reprocessable Photodeformable Azobenzene Polymers [PDF]
Molecules, 2021 Photodeformable azobenzene (azo) polymers are a class of smart polymers that can efficiently convert light energy into mechanical power, holding great promise in various photoactuating applications. They are typically of crosslinked polymer networks with highly oriented azo mesogens embedded inside. Upon exposure to the light of appropriate wavelength,

ROTf-induced annulation of heteroatom reagents and unsaturated substrates leading to cyclic compounds [PDF]
Royal Society Open Science, 2018 The development of metal-free organic reactions is one of the hotspots in the synthesis of cyclic compounds. ROTf (alkyl trifluoromethanesulfonates), due to their good electrophilicity, are powerful alkylating reagents at heteroatoms such as nitrogen ...

Azoporphyrin: The Porphyrin Analogue of Azobenzene [PDF]
Angewandte Chemie International Edition, 2007 Azobenzenes (1,2-diaryldiazenes) are very important organic pigments, and they have a unique place in the field of photoresponsive conjugated molecules due to their (usually) reversible E/Z photoisomerisation. The current intense interest in molecular analogues of mechanical components and information storage and processing elements has stimulated ...

Design and synthesis of a photoswitchable guanidine catalyst
Beilstein Journal of Organic Chemistry, 2012 A novel design as well as a straight-forward synthesis for a photoswitchable guanidine catalyst is reported. Intense studies of the photochromic properties demonstrated the reversible switchability of its photosensitive azobenzene moiety. Its activity in

A combinatorial approach to improving the performance of azoarene photoswitches
Beilstein Journal of Organic Chemistry, 2019 Azoarenes remain privileged photoswitches – molecules that can be interconverted between two states using light – enabling a huge range of light addressable multifunctional systems and materials.

Control over molecular motion using the cis–trans photoisomerization of the azo group
Beilstein Journal of Organic Chemistry, 2012 Control over molecular motion represents an important objective in modern chemistry. Aromatic azobenzenes are excellent candidates as molecular switches since they can exist in two forms, namely the cis (Z) and trans (E) isomers, which can interconvert ...

Synthesis of mono-functionalized S-diazocines via intramolecular Baeyer–Mills reactions
Beilstein Journal of Organic Chemistry, 2018 Herein we report a reliable method to synthesize mono-functionalized S-diazocines in reproducible yields via intramolecular Baeyer–Mills reactions. Diazocines exhibit excellent photoswitchable properties. As opposed to azobenzenes they are more stable in

Fluorinated azobenzenes as supramolecular halogen-bonding building blocks
Beilstein Journal of Organic Chemistry, 2019 ortho-Fluoroazobenzenes are a remarkable example of bistable photoswitches, addressable by visible light. Symmetrical, highly fluorinated azobenzenes bearing an iodine substituent in para-position were shown to be suitable supramolecular building blocks ...
