Recently, interfacial layer such as metal oxide, insulator and polymer have been used by scientists between the semiconductor to increase stability of metal-semiconductor heterojunctions. These materials varied according their usage aims. In this study, graphene nanoribbons (GNR) 7,7,8,8 Tetracyanoquinodimethane (TCNQ, C12H4N4) has for photodiode applications. The TCNQ collects extracts more el...

We studied cocrystal of bis(8-quinolinolato) copper(II) (CuQ2) and 7,7,8,8-tetracyanoquinodimethane (TCNQ), which change dramatically crystal shape in a moment by adding press on face. Single was prepared dissolving CuQ2 TCNQ chloroform evaporation the solution at ambient conditions. investigated about structure morphological properties. proclaim that this phenomenon is solid phase transition t...

We have characterized the terahertz (THz) vibrational spectroscopy of organic polycrystalline thin films using the new experimental technique of waveguide terahertz time domain spectroscopy (waveguide THz-TDS). The organic materials used in this study are tetracyanoquinodimethane (TCNQ) and 1,3-dicyanobenzene (13DCB). For each material, a thin film is cast onto one of the inner surfaces of a me...

Purpose: To develop and validate simple, rapid and sensitive spectrophotometric procedures for determination of trimipramine in tablet dosage form. Methods: The methods were based on the interaction of trimipramine as n-electron donor with the acceptor, iodine and various -acceptors, namely: chloranil (CH), chloranilic acid (ChA), 2,3-dichloro-5, 6-dicyano-1, 4-benzoquinone (DDQ), and 7, 7,8,...

Two quinonoid bis(dicyanomethylene) oligothiophenes, terthiophene and quaterthiophene analogues of TCNQ, have been investigated by spectroelectrochemical experiments and density functional theory calculations. Electrochemical data show that the molecules can be both reduced and oxidized at relatively low potentials, and that the quaterthiophene derivative forms four stable redox species, the di...

Carbon nanotubes (CNTs) has drawn extensive attention for flexible thermoelectric (TE) applications due to its unique electronic properties, mechanical robustness, and lightweight, however, low figure of merit (ZT) greatly limits practical use in device application. In this study, we tuned the carrier concentration pre-formed CNT yarns by a vapor-phase doping process under atmospheric pressure ...

– The solution to the long standing problem of the cohesion of organic chain compounds is proposed. We consider the tight-binding dielectric matrix with two electronic bands per chain, determine the corresponding hybridized collective modes, and show that three among them are considerably softened due to strong dipole-dipole and monopole-dipole interactions. By this we explain the unusual low f...
