A new chromophore HK containing the cis,cis-1,7-diethoxy-3-isopropyljulolidine group as a novel electron-donor, thiophene as a π-conjugated bridge and a tricyanofuran (TCF) acceptor has been synthesized and systematically investigated in this paper. Its corresponding chromophore FTC using 4-(diethyl amino)benzyl as the electron donor group was also prepared for comparison. This is the first tim...

Quantum mechanical calculations of different energies components of 1,10-phenanthroline in ground state were carried out by DFT method , in isolated state and in various solvents to study the effects of solvents on various energy components and global properties. The solvation energy, chemical potential, hardness, electrophilicity of 1,10-phenanthroline were calculated with the help of computed...

Using photoelectron spectroscopy and first principles molecular orbital calculations, we report the first observation of an abrupt change in the electronic structure of W4O m (m6 6) clusters at m 1⁄4 5 which is well below the bulk stoichiometric composition of tungsten oxide (WO3). The signature of this onset is established from an anomalous increase in the vertical detachment energies (VDE), a...

As cancer is the top killer diseases in the world, the scientists and researchers have been searching the new drugs and remedy methods. Most of the anticancer drugs are organic compounds which were approved by the FDA while metallodrugs are very rare. In the present time, some palladium and rhodium complexes are going to use as anticancer molecules. The palladium (II) complex has higher antican...

a novel pyridine-2,6-dicarboxylic acid mixed ligands complex of formula [co(no3)2].6h2o has been obtained by the reaction of pyridine-2,6-dicarboxylic acid with cobalt nitrate and 1,10-phenanthroline on heating in water. the structures of [co(pydc)(phen)(h2o)](pydch2).4h2o receptors, and their complexes were optimized using dft method at the b3lyp/3-21g** level. the highest occupied molecular o...

in this paper, the structural properties of c20 and c12b8 fullerene interacting with glycine based onthree active sites of glycine and one c atom or one b atom in c12b8 were analyzed through thedensity functional theory. it was found out that the binding of glycine to c12b8 generated a complex.our results were extremely relevant in order to identify the potential applications of functionalizedc...

The reactions of propenyl magnesium halides with ethylene were studied using ab initio calculations. The structure of the transition state and the ground state were evaluated and obtained the structural properties, theoretical thermodynamic and kinetic data i.e. rate constants of the reactions. The methods used for calculations are RHF, B3LYP and MP2 with 6-31G* b...

Our recently proposed theoretical formulation based on Bethe–Salpeter G(0)W(0) methodology is applied here to explore the quasiparticle and optical spectra of anthracene (C(14)H10) placed close to a metallic surface. Special attention is paid to explore how the energy shift and decay width of the low-lying anthracene bright excitons p, α and β depend on the type of the adjacent surface (describ...

Gold nanoclusters have the tunable optical absorption property, and are promising for cancer cell imaging, photothermal therapy and radiotherapy. First-principle is a very powerful tool for design of novel materials. In the present work, structural properties, band gap engineering and tunable optical properties of Ag-doped gold clusters have been calculated using density functional theory. The ...
