Enhancement of electronic and charge transport properties of NiPc by potassium-tetrasulpho group

We report significant enhancement in the electronic properties of nickel phthalocyanine (NiPc) by attaching a potassium-tetrasulpho functional group to synthesize its water soluble derivative nickel (II)4,4′,4″,4'″potassium-tetrasulphophthalocyanine (K4NiTSPc). To study the potential of this organic compound for electronics applications, Au/K4NiTSPc/Ag diodes have been fabricated and their electronic parameters have been calculated. The mobility and conductivity of the device have been found to be 1.5×10−4 cm2 V−2 S−1 and 2.5×10−4 Ω−1 cm−1. The K4NiTSPc has shown much better electronic properties as compared to NiPc reported in the literature, which makes it a promising candidate for its potential use in electronics applications
