A novel polyphenol-based ferromagnetic polymer: synthesis, characterization and Schottky diode applications

A polyphenol-derivative ferromagnetic poly- mer was successfully synthesized from oxidative poly- condensation of 4-(1-(2-phenylhydrazono)ethyl)benzene- 1,3-diol abbreviated as 2,4-PHEB, and the obtained mate- rials were fully characterized by using UV-Vis absorption spectroscopy, Fourier transform infrared, nuclear magnetic resonance and single crystal X-ray diffraction techniques. The optical, electrochemical, fluorescence, magnetic and thermal properties of the newly synthesized compounds were investigated in detail. The results revealed that the poly(2,4-PHEB) had ferromagnetic and semi-conductive (1.59 S/cm) properties. Additionally, the poly(2,4-PHEB)/ p-type Si junction device is fabricated, and it was
