A novel imidazole derivative with functional group and pi-conjugated system, 1-[trans-4-(4-diethylaminostyryl)phenyl]imidazole (abbreviated as L), and its Co-II complex (CoCl2L4)(2) (Co2C168H184N24Cl4, M-r = 2799.05) have been synthesized and the crystal structure of the latter was determined by X-ray diffraction. The crystal is of triclinic, space group P (1) over bar with a 8.823(3), b = 18.799(7), c = 23.065(9) angstrom, alpha = 77.349(6), beta = 83.128(7), gamma = 80.942(3)degrees, V 3671.5(12) angstrom(3), Z = 1, D-c = 1.266 g/cm(3), mu = 0.361 mm(-1), F(000) = 1482, the final R = 0.0587 and wR = 0.1284 for 6562 observed reflections with I > 2 sigma(I). In the molecular, structure of (CoCl2L4)(2), there are two crystallographically unique units. The Co-II atoms are six-coordinated by four N atoms from four imidazole ligands (L) and two Cl atoms to form a distorted octahedral geometry. The optical properties of complex (CoCl2L4)(2) have been experimentally studied.

Spectroscopic determination of acid dissociation constants of some imidazole derivatives

The acid dissociation constants, pK(a), of eight biologically active imidazole derivatives were determined using a spectroscopic technique. Using the obtained acid dissociation constants, attempts were made to elucidate the structures and protonation mechanisms of these derivatives. Four of eight molecules were found to behave as Hammett base for the first protonation.

Novel Ru(II) Complex with 1H-Benzo[d]Imidazole Derivative for Dye-Sensitized Solar Cell

It was reported that ruthenium(II) complex CBTR with 1H-benzo[d]imidazole derivative for heteroleptic donor system exhibited an enhancement of the solar cell performance, compared to N3. We took a theoretical approach about the CBTR dye. Density functional theory (DFT) and time-dependent density functional theory (TD-DFT) calculations were used to gain insight into the factors responsible for the photovoltaic properties of the dye sensitizer. The values of the absorption spectrum of the CBTR dye with the 1H-benzo[d]imidazole derivative were not improved compared to those of the N3 dye. The lack of improvement was attributed to the destabilization of the lowest unoccupied molecular orbital (LUMO) energy level of the CTBR dye. According to the molecular orbital analysis, the LUMO of the CBTR dye mainly localized on the dcbpy (dcbpy = 4,4′-dicarboxy-2,2′-bipyridine) moiety. The highest occupied molecular orbitals (HOMOs) of N3 were localized on the Ru-NCS moiety, and the HOMOs of CBTR were also localized on Ru-NCS. The introduction of the 1H-benzo[d]imidazole derivative to the heteroleptic donor system did not change the location of the HOMOs. The addition on of the NHC ligand to the CBTR dye seems to be an essential structural modification to enhance the efficiency of solar cells.

Fluorescence spectral studies of some imidazole derivatives

The photophysical properties of imidazole derivatives namely 2-(2,4-difluorophenyl)-4,5-dimethyl-1-p-tolyl-1H-imidazole and N,N-dimethyl-4-(4,5-dimethyl-2-phenyl-1H-imidazol-1-yl)benzenamine,synthesized from an unusual four components assembling, were studied in several solvents. Polarization also plays major role in the increase of excited-state dipole moment (mu(e)). From the spectral results, it was found that there is equilibrium between neutral species and monocationic (MC) species in polar aprotic and polar protic solvents. The basicity of the solvent, C-beta or C-SB has a negative value, suggesting that the absorption and fluorescence bands shift to lower energies with increasing electron-donating ability of the solvent. Therefore, resonance structures 1b and 2b has the positive charge located at the nitrogen atom stabilized in basic solvents. (C) 2012 Elsevier B.V. All rights reserved.

Synthesis, Crystal Structure, Kamlet-Taft and Catalan Solvatochromic Analysis of Novel Imidazole Derivatives

Novel imidazole derivatives were synthesized and its crystal structure has been studied by single crystal XRD analysis. The photophysical properties of these imidazole derivatives were studied in several solvents, which include a wide range of apolar, polar and protic media. The observed lower fluorescence quantum yield may be due to an increase in the non-radiative deactivation rate constant. This is attributed to a loss of planarity in the excited state provided by the non co-planarity of the aryl rings attached to C(2) and N(1) atoms of the imidazole ring. Such a geometrical change in the excited state leads to an important Stokes shift, reducing the reabsorption and reemission effects in the detected emission in highly concentrated solutions. The highest fluorescence quantum yield of the imidazole derivatives are observed in polar media.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 60-56-0. Computed Properties of C4H6N2S.

A study on the binding interaction between the imidazole derivative and bovine serum albumin by fluorescence spectroscopy

The interaction between the imidazole derivative 2-(2,4-difluorophenyl)-1-phenyl-1H-imidazo[4,5-f] [1,10]phenanthroline (dfppip) and bovine serum albumin (BSA) was investigated by fluorescence and UV-vis absorbance spectroscopy. From the experimental results, it was found that the imidazole derivative has strong ability to quench the intrinsic fluorescence of BSA by forming complexes. Electrostatic interactions play an important role to stabilize the complex. The binding constants and the number of binding sites have been determined in detail. The distance (r) between the donor and the acceptor was obtained according to fluorescence resonance energy transfer (FRET). Conformational changes of BSA were observed from synchronous fluorescence spectroscopy. The effect of metal ions such as Cu2+, Zn2+, Ca2+, Mg2+, Ni2+, Co2+ and Fe2+ on the binding constants between the imidazole derivative and BSA were also studied. (C) 2011 Elsevier B.V.

Development and characterization of imidazole derivative cured bisphenol A epoxy materials for flip-chip underfill applications

This paper is targeted to provide underfill manufacturers and electronic packaging companies with general information about imidazole derivative cured bisphenol A epoxy materials. Four selected imidazole derivatives and one bisphenol A epoxy resin were investigated in this paper. Differential Scanning calorimetry (DSC) was used to study the curing kinetics of the prepared formulations and glass transition temperature (Tg) of the cured formulation. Thermo-Mechanical Analyzer (TMA) was used to investigate the heat flex temperature and coefficient of thermal expansion (CTE). Dynamic-Mechanical Analyzer (DMA) was used to measure the storage modulus (E’) and cross-linking density (rho) at the temperature range from 25 degrees C to 250 degrees C of the cured materials. A rheometer was used to investigate the viscosity (eta) of these formulations. The effects of the curing agent type and concentration on the curing kinetics, Tg, CTE, E’, rho, and eta were then investigated. The correlation between CTE (above Tg) and crosslinking density was examined and discussed.
