Organic compounds like 2,2’-Bithiophene (with a synonym. 2,2'-bithienyl, 2,2'-dithienyl)-containing bis(dioxaborin) have drawn significant concern in the area of materials science because their electron affinity and luminescent properties. With this motivation, we been concentrating on properties functions 2,2'-Bithiophene. The vibrational frequencies molecule 2,2'-Bithiophene solid phase were ...
Electron transporting (n-channel) polymer semiconductors for field-effect transistors are rare. In this investigation, the synthesis and characterization of new electron-depleted N-alkyl-2,2'-bithiophene-3,3'-dicarboximide-based pi-conjugated homopolymers and copolymers containing the 2,2'-bithiophene unit are reported. A novel design approach is employed using computational modeling to identif...
Formation of the first binary stacks of an intact organocopper aggregate with the arenes naphthalene and 2,2'-bithiophene is reported; crystallographic data suggest that the supramolecular assembly process is supported by Cu-pi, Cu-S, and perfluoroarene-arene pi-interactions.
New symmetrical arylene bisimide derivatives formed by using electron-donating-electron-accepting systems were synthesized. They consist of a phthalic diimide or naphthalenediimide core and imine linkages and are end-capped with thiophene, bithiophene, and (ethylenedioxy)thiophene units. Moreover, polymers were obtained from a new diamine, N,N'-bis(5-aminonaphthalenyl)naphthalene-1,4,5,8-dicarb...
Self-assembled monolayers (SAMs) of tripod-shaped trithiols, consisting of an adamantane core with three CH2SH legs and a bithiophene group, were prepared on a Au(111) surface. Adsorption in a tripod-like fashion was supported by polarization modulation-infrared reflection absorption spectroscopy (PM-IRRAS) of the SAMs, which indicated the absence of free SH groups. Cyclic voltammetry showed an...
A facile method for the functionalization of multiwall carbon nanotubes (MWCNT) by photopolymerization of 5-mercapto-2,2'-bithiophene modified metal (Au or Ag) nanoparticles on the surface of the MWCNT is developed.
The computational elucidation and proper description of the ultrafast deactivation mechanisms of simple organic electronic units, such as thiophene and its oligomers, is as challenging as it is contentious. A comprehensive excited state dynamics analysis of these systems utilizing reliable electronic structure approaches is currently lacking, with earlier pictures of the photochemistry of these...
In order to study the variation of electronic properties, a set of bithiophene derivatives has been developed. Here, the effect of substitution on the aromaticity properties of some cyclic bithiophene derivative compounds was investigated using theoretical calculations. Calculations were performed at B3LYP/6-31+G (d,p) level; and calculated properties included energy, dipole moment, total c...
