Abstract
In this study, a new ferrocene-decorated cyclotriphosphazene compound (4) was obtained by the interaction of ferrocene chalcone with azide end groups (2) and spirophosphazene (3) bearing alkyne groups using the click method. The structures of all compounds were confirmed using Fourier transform infrared, 1H, 13C APT, and 31P NMR, and MS techniques. The optical band gaps of compounds were measured, showing values of 4.75 eV for 3, 3.53 eV for 2, and 3.46 eV for final product 4. The optical band gap of compound 4 calculated by density functional theory is 3.28 eV. The electrical properties of the compounds were investigated against the frequency. The results showed that the conduction mechanism is based on the hopping model. New types of diodes were prepared by using compounds 2 and 4. The current–voltage characteristics of the compound 4 diode showed good rectification behavior. The rectification ratio of the heterojunction diode was calculated as 629. The ideality factors were 3.35 for 2 and 7.57 for 4. The barrier heights were 0.68 and 0.92, respectively. Under sunlight (20–100 mW/cm2), both diodes exhibited photodiode properties, with compound 4 being more sensitive to light. This indicates that the diodes can be used in optoelectronic devices due to their photoconductive behavior.
