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 strongly absorbing heptazine core and the emitting tetrazine units. This molecule has been used to functionalize reduced graphene oxide by an easy process resulting in a material able to store charges by a dual faradaic and capacitive mechanism.
