Syntheses, structures, surface photovoltage and luminescent properties of a novel lead(II) coordination polymer containing anthracene chromophore

• A novel 1D lead(II) coordination polymer containing anthracene chromophore was synthesized.
• Surface photovoltage spectroscopy and luminescent properties of the compound were studied.
• The 1D molecular nanowires with a diameter of 1.22 nm were observed in the compound.

A novel 1D lead(II) coordination polymer containing anthracene chromophore through the employment of hydrothermal techniques by using 9-anthracenecarboxylic acid and PbI2, [Pb(9-aca)2(H2O)2] (1) (9-acaH = 9-anthracenecarboxylic acid) has been synthesized and structurally characterized by X-ray single-crystal diffraction as well as by powder X-ray diffraction and elemental analysis. In compound 1, each PbO8 polyhedron is linked to each other by oxygen atoms from 9-acaH ligand to form a 1D molecular nanowire with a diameter of 1.22 nm. Surface photovoltage spectroscopy (SPS) and field-induced surface photovoltage (FISPS) of compound 1 indicate that it possesses positive SPV response in the range of 300–800 nm and shows p-type semiconductor characteristic. Luminescent properties of compound 1 reveal that the compound exhibit strong luminescence, ascribed to the charge transfer of anthracene chromophore and the semiconductor 1D Pb2O2 chain.
