Diverse carbon nitride solids are presumably one of the most promising candidates to complement carbon in materials application. Y. Zhang and M. Antonietti, in their Communication on page 1307 ff., observe that polymeric carbon nitrides have a photovoltaic effect and are promising in solar energy conversion, exhibiting reasonable efficiency as well as other merits including low cost, facility for mass-synthesis/chemical modification, and, in particular, contrary to many other organic semiconductors, a high chemical stability against oxidation (stable in air up to 550 oC).
