An N‐heteropentacene, 1,2,5,6‐tetra(5‐hexylthiophene‐2‐yl)‐hexaazapentacene ( 4HP ), was synthesized through one‐step cyclocondensation reaction. The binding behavior of 4HP toward various cations (Ca 2+ , Cd 2+ , Co 2+ , Cr 2+ , Cu 2+ Fe 3+ , Hg 2+ , K + , Li + , Mg 2+ , Mn 2+ , Na + , Ni 2+ , Zn 2+ , and Pb 2 ) was investigated by UV/vis and fluorescence spectroscopy. 4HP demonstrated a selective and sensitive response towards Cu 2+ ion, and the detection limit reached 1.2 μ M in N , N ‐dimethylformamide solution.
