In this research, a series of Ru(II) complexes, ([Ru(1-7)(ina)(NCS)2] (1-7=5-[6-(5-mercapto-1,3,4-oxadiazol-2-yl)pyridin- 2-yl]-1,3,4-oxadiazole-2-thiol’s, ina=isonicotinic acid) were synthesized and characterized using different spectroscopic and analytic techniques, such as NMR, UV, IR, CV and CHN. Also, the new complexes were used in dye-sensitized solar cells (DSSC) as sensitizers. Current-voltage characteristics showed that the modifications of ligands clearly affected DSSC yield. Additionally, DFT calculations were performed and showed locations of frontier molecular orbitals of the complexes. While the locations of HOMO and HOMO – 1 orbitals are on Ru(II) metal center and SCN− ligands, the location of LUMO and LUMO + 1 orbitals are on the 1-7 ligands.

Herein, aromatic polyimides (API) synthesis was carried out by polycondensation of the original diamine (new synthesis) and commercial dianhydride. The original diamine and API were characterized by different analysis techniques. In addition, experimental and quantum chemical calculations of the synthesized API were analyzed by density functional theory method. Quantum theory analysis of atoms in molecules was performed for a structural unit of the compound. Here, the proton transfer phenomenon was investigated. The main purpose of synthesizing API1 was diode application. Therefore, the Au/API-p-Si/Al diode was produced accomplishedly. When the electrical characterization of the obtained diode structure was made, electrical parameter values such as ideality factor (n) (between 1.9 and 3.8), barrier height (Φ B ) (0.73-0.28 eV), and series resistance (R s ) (1270-40,187 kΩ) were calculated.

Small Molecule Based Organic Photo Signal Receiver for High‐Speed Optical Wireless Communications

The present work describes the development of an organic photodiode (OPD) receiver for high-speed optical wireless communication. To determine the optimal communication design, two different types of photoelectric conversion layers, bulk heterojunction (BHJ) and planar heterojunction (PHJ), are compared. The BHJ-OPD device has a −3 dB bandwidth of 0.65 MHz (at zero bias) and a maximum of 1.4 MHz (at −4 V bias). A 150 Mbps single-channel visible light communication (VLC) data rate using this device by combining preequalization and machine learning (ML)-based digital signal processing (DSP) is demonstrated. To the best of the authors' knowledge, this is the highest data rate ever achieved on an OPD-based VLC system by a factor of 40 over the previous fastest reported. Additionally, the proposed OPD receiver achieves orders of magnitude higher spectral efficiency than the previously reported organic photovoltaic (OPV)-based receivers.
