Pentatomic carbon ring conjugated nitrogen-doped nanographene†
Abstract
A π extended N-doped nanographene molecule with pentatomic carbon ring conjugation was synthesized. The molecule, 1,14-dichloro-6,9-dimethoxyquinolino[2′,3′,4:3,4]indeno[2,1,7-ghi] phenanthridine (1), exhibited potential as a metal cation and proton receptor with a UV-vis and fluorescence response to selected metal cations (e.g., Zn2+, Zr4+, Ag+, Cu2+, or Cd2+) or protons.
