s-Tetrazines¹, and the far more enigmatic heptazines², which count much less described examples, are among the most electron deficient high-nitrogen content, stable aromatic heterocycles (Fig. 1). This peculiarity confers them very original physico-chemical characteristics, including delayed fluorescence, a high electrochemical reduction potential, and a strong potential in organic photocatalysis. In addition, heptazines can trigger enhanced electron transport in OPV devices. However, their synthetic approach, for heptazines, is still in its infancy. We will present and comment on new strategic synthetic procedures involving these two families, insisting more on heptazines recent results, and new properties.

This lecture will therefore recall new synthetic advances in both fields of tetrazines, and heptazines. Noticeably, a new synthetic procedure of heptazines using mechanochemistry, elaborated in the PPSM laboratory, will be presented. As well, we will describe new very low-viscosity tetrazine-based fluorescent liquids. The original delayed fluorescence of original heptazines, which are the first species to present sometimes a singlet-triplet inversion, will be detailed, along with first results in photocatalysis. Examples featuring the molecules concerned are gathered in the Scheme 1 below.

Olivier joined ICPEES as independent young researcher (Chargé de Recherche) in February 2023. His interests are in understanding the chemical and electrochemical doping mechanisms of highly structured organic semiconductors for bioelectronic and thermoelectric applications. A physicist by training, he obtained his MSc in Nanoscience and Engineering Physics at the Grenoble Institute of Technology (Phelma, France) in partnership with Imperial College London (UK). To better understand the molecular design of the materials he was studying, he completed a PhD at Université Grenoble Alpes/CEA Grenoble (France) with Dr. Renaud Demadrille from 2016 to 2019. He focused on the organic synthesis of n-type polymers and their doping for thermoelectric and photovoltaic applications. From 2020 to 2023, he developed his skills in time-resolved spectroscopy and data analysis during a post-doctoral stay in the FemtoMat group of Prof. Natalie Banerji at the University of Bern. Notably, he improved the electronic performance of organic electrochemical transistors (OECTs) and identified energetical and morphological factors limiting the (de)doping kinetics of the polymer channel during device operation.
