Controllable synthesis of 6H-1,4-diazepine-2,3-dicarbonitrile nanocrystals and their optical properties.


Organic nanostructures of 6H-1,4-Diazepine-2,3-dicarbonitrile (HDD) ranging from nanoparticles to nanoribbons have been controllably prepared. Changes in morphologies are observed to be accompanied with changes in optical properties. The HDD nanoparticles show a main emission at ca. 710 nm with a very weak shoulder at 625 nm, as nanoparticles gradually grow… (More)
