Synthesis and optical properties of iron(<scp>iii</scp>) complexes of 2-benzylidene-1-indanone derivative thin films

In this work, we propose a method to synthesize vanadium (IV) 2-benzyli-dene-1-indanone derivatives, used to prepare film structures by thermal evaporation. The complexes possess high melting point allowing the using of vacuum deposition methods. All the samples were grown at room temperature (25˚C) and low deposition rates (0.4 Å/s). The surface morphology and structure of the deposited films were studied by scanning electron microscopy (SEM) and spectroscopy dispersive energy (EDS). Optical absorption studies of the complex films were performed in the 200 -1100 nm wavelength range. The Tauc band gap (Eg) of the thin films was determined from the (αhν) 1/2 vs. hν plots for indirect transitions. The vanadium (IV) complex films show optical activation energies in the range of organic semiconductors. Multilayer nylon 11/vanadium indanone devices were fabricated using ITO and silver electrodes. The d.c. electrical properties of the device were also investigated. It was found that the temperature-dependent electric current in the structure showed a semiconductor behavior. At lower voltages below 7 V, the current density in the forward direction was found to obey an ohmic I-V relationship; for higher voltages above 7 V, the conduction was dominated by a space-charge-limited (SCLC) mechanism. The electrical activation energies (Ea) of the complexes were in the 2.17 -2.31 eV range.

“…Preliminary results of the study of iron(III), organotin(IV) and vanadium(IV) complexes of aryl hydroxymethylidene indanone derivatives as thin films showed electronic properties potentially useful in the production of optoelectronic devices. [11][12][13][14][15][16] With this in mind, the main goal of the present work is the synthesis and characterization of new copper(II) complex of 2benzylidene-1-indanones derivatives. The optical properties of the complexes were also studied to determine their possible application as active layers in type SMOLED devices.…”

“…Among the low molecular weight compounds, copper(II) complexes derived from 2-benzylidene-1-indanones are stable solids that stand out due to their exceptional properties such as containing a conjugated system, the presence of at least one transition metal, a crystalline structure, and a high melting point. These characteristics are essential for the compound to be studied as an organic semiconductor, previous work has been done with tin [11] and metallic atoms of the transition block, [12][13][14] however copper(II) complexes derived from 2-benzylidene-1-indanones have been little studied. Preliminary results of the study of iron(III), organotin(IV) and vanadium(IV) complexes of aryl hydroxymethylidene indanone derivatives as thin films showed electronic properties potentially useful in the production of optoelectronic devices.…”

A series of copper(II) molecular materials derived from 2‐benzylidene‐1‐indanones were synthesized in order to investigate the influence of their structure on their optical and semiconductor behavior. The molecular materials were structurally characterized by IR spectroscopy, mass spectrometry, and X‐ray diffraction. Additionally, thin films of copper complexes were successfully deposited by thermal evaporation, and the optical and electrical features of films were examined using UV‐vis spectroscopy and current‐voltage measurements, respectively. Subsequently, the structures of copper(II) complexes were optimized by density functional theory (DFT), and the energy values of the single occupied molecular orbital (SOMO) and lowest unoccupied molecular orbital (LUMO) were calculated. According the DFT calculations, the copper complexes show fluxional isomerism. Theoretical bandgap values were found to be consistent with those experimentally obtained and showed to be closely related with the p‐semiconductor behavior of copper complexes, which at the same time depends on the substituents in the structure.
