In order to increase the species of organic semiconductors, new Zn-phthalocyanines-based organic materials were synthesized and characterized. The new compounds have been characterized by 1 H and 13 C using NMR, FTIR, and UV-Vis. The absorption, fluorescence, and electrochemical properties were also studied. Green photoluminescence was observed in dilute solutions. In solid thin films, - * interactions influenced the optical properties, and redshifted photoluminescence spectra were obtained; red emissions for ZnPAL (647 nm) and ZnPTr (655 nm) were found. By cyclic voltammetry, the electrochemical band gap was estimated to be 1.94 and 1.17 eV for ZnPAl and ZnPTr, respectively. Single-layer diode devices of an indium tin oxide/Znphthalocyanine/aluminum configuration were fabricated and showed relatively low turn-on voltages (3.3 V for ZnPAl and 3 V for ZnPTr).
One novel Zn-phthalocyanine bearing different substituent was synthesized. The resulting compounds were characterized by NMR and FTIR. The corresponding polymer was synthesized via cyclic voltametry. The optical properties of these π-conjugated systems were investigated by UV-Visible absorption and photoluminescence (PL) spectroscopy. The electrochemical behavior was reported. The optical and electrochemical gaps were estimated. Those complexes, having low gap energy, have been identified as holding much promise for the developpement of photovoltaic device.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
