Synthesis, characterization, and sensing behavior of an N-heteropentacene

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 (Ca2+, Cd2+, Co2+, Cr2+, Cu2+ Fe3+, Hg2+, K+, Li+, Mg2+, Mn2+, Na+, Ni2+, Zn2+, and Pb2) was investigated...

Description
Summary: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 (Ca2+, Cd2+, Co2+, Cr2+, Cu2+ Fe3+, Hg2+, K+, Li+, Mg2+, Mn2+, Na+, Ni2+, Zn2+, and Pb2) was investigated by UV/vis and fluorescence spectroscopy. 4HP demonstrated a selective and sensitive response towards Cu2+ ion, and the detection limit reached 1.2 μM in N,N-dimethylformamide solution.
