Synthesis and Characterization of a [1,2,6]Diazaphosphonine Oxide: An Example of a Photoswitchable Phosphorus-Containing Cyclic Azobenzene

We report herein the synthesis and characterisation of a phosphorus-containing cyclic azobenzene, as a new photoswitchable scaffold. This backbone reveals high bidirectional photoswitching yields and high thermal stability of both isomers, with t1/2…

Palladium‐Catalyzed Indirect and Regioselective Phosphonation of Azobenzenes: Toward the Design of Water‐Soluble Photoswitches

An efficient palladium‐catalyzed ortho C−H acyloxylation of azobenzenes, allowing the introduction of the difunctionalised substituent, diethylphosphonoacetate, is reported. Thanks to the mild reaction conditions implemented, this regioselective…

Heptazine derivative bearing tetrazine capped arms: A new fluorescent and redox platform for reduced graphene oxide functionalization

We have synthesized the first example of a heptazine molecule bearing three arms, each of them functionalized by a tetrazine at the end. This new original molecule is redox active and fluorescent, benefiting from the energy transfer between the…
