• different chemical treatments (hydrothermal and pyrolytic methods). The effect of nitrogen doping on the performance of the examined CDs has been also investigated. Results and Discussion Synthesis, photophysical and electrochemical properties of CDs. As hinted above, CDs have been prepared from different

• achieved with one-pot Suzuki–Miyaura coupling to arrange phenylene rings and pyridinylene rings in an alternating fashion. Analyses with UV–vis spectroscopy showed changes in the photophysical properties with nitrogen doping, and X-ray crystallographic analyses experimentally revealed the presence of

• biased charges on the peripheral nitrogen atoms. Keywords: cross coupling; macrocycles; nitrogen doping; UV–vis spectroscopy; X-ray charge density analysis; Introduction Graphitic carbonaceous sheets of graphene continue to attract considerable attention, which lead us to explore structural defects
