Tunable Carrier Type of a Semiconducting 2D Metal-Organic Framework Cu₃(HHTP)₂.

ABSTRACT: In this work, a switch from n-type to p-type conductivity in electrodeposited Cu₃(2,3,6,7,10,11-hexahydroxytriphenylene)₂ [Cu₃(HHTP₂)] has been observed, which is most likely due to oxygen molecular doping. The synthesis of electrically conductive 2D metal-organic frameworks (MOFs) has been achieved through the introduction of highly conjugated organic linkers coordinated to their constituent metal-ion centers. However, the porous structure and unsaturated metal sites in MOFs make them susceptible to ambient adsorbates, which can affect their charge transport properties. This phenomenon has been experimentally investigated by GIXRD, Hall effect and Seebeck measurements, and X-ray photoelectron spectroscopy.
