Abstract

An in situ surface-reaction approach has been developed for the synthesis of microcrystals Cu4I4 (C6H5N)4, Cu4I4 (C9H7N)4, and Cu2I2 (C8H6N2) in solid films. Microcrystals of Cu4I4 (C6H5N)4, Cu4I4 (C9H7N)4, and Cu2I2 (C8H6N2) were easily formed on a copper substrate at the solid Cu-liquid pyridine (C6H5N),-quinoline (C9H7N), and-quinoxaline (C8H6N2) interfaces. The resulting microcrystal films were characterized by photoluminescence spectroscopy, scanning electron microscopy, transmission electron microscopy, energy dispersive x-ray spectroscopy, x-ray diffraction, and electrochemical impedance spectroscopy. The effect of ligands on the morphology of the film materials and their chemical properties were also discussed. These microcrystal films possessing reversible photocurrent and photovoltage properties were studied in detail. The photoactive and mechanically stable complex films described here may provide new strategies for fabricating photoluminescence solid films, photomodulation potential, and current films. The potential applications of the microcrystal films are for small light-induced electronic junction and photoluminescence sensors.
