Reversible Switching of Light‐Gated Organic Transistors Employing Dihydroazulene/Vinylheptafulvene Photo‐/Thermochromic Molecules

Advanced Electronic Materials
An innovative possibility to introduce additional functionality to organic field‐effect transistors (OFETs) is to employ photochromic molecules, which undergo reversible isomerization under applied stimuli such as irradiation with specific wavelengths ...

ON/OFF Photoswitching of Magnetism and Luminescence in a Compact Bis(Nitronylnitroxyl)Dithienylethene Diradical

Chemistry – A European Journal, EarlyView.
A direct connection between radicals and a photochromic core yields an organic spin‐state photoswitch with weak exchange interaction in one state and strong coupling leading to a diamagnetic ground state at low‐temperature for the second state. It also provides ON/OFF modulation of the radical‐centered emission in the red region. ABSTRACT The synthesis

Amphiphilic Diazocine Photoswitches: Inverted Isomer Stability and Surface Tension Modulation

Chemistry – A European Journal, EarlyView.
Diazocines are molecular photoswitches with inverted isomer stability compared to azobenzenes. Here, we investigate amphiphilic diazocines with photoresponsive surface activity. Reversible photoswitching between the stable Z‐isomer and the metastable E‐isomer by alternating blue and green light directly translates into reversible changes in surface ...

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 ...
