C60 is the third form of elementary C, which was discovered in recent *** C60, each C atom links with three adjacent C atoms in terms of sp2-like hybridorbitals, in which there are two long bonds and one short bond. At present, sincemacro-quantity of C60 is able to be produced with simple method, interest instudy on C60 shifts to its chemical properties from the structure. （P（C6H5）3）2Ptand C60 themselves are stable valence-saturated molecules, however, they can form sta-ble complexes through the charge transfer, in which （P（C6H5）3）2 Pt is complexed

The formation of charge transfer complex between iodine with 4＇-nitrobenzo-15-crown-5（NB15C5） and benzo-15-crown-5 （B15C5） is investigated spectrophotometrically in chloroform and dichloromethane（DCM） solutions at 25℃.The pseudo-first-order rate constants for the transformation process were evaluated from the absorbance-time data and found to vary in the order of DCM CHCl_*** values of the formation constant,K_f,for each complex are evaluated from Benesi-Hilebrand equation. Stability of the resulting complex in two solvents was also found to vary in the order of DCM CHCl_3.

The driving voltage of an organic light-emitting diode（OLED） is lowered by employing molybdenum trioxide（MoO3）/N,N＇-bis（naphthalene-1-yl）-N,N＇-bis（phe-nyl）-benzidine（NPB） multiple quantum well（MQW） structure in the hole transport *** the device with double quantum well（DQW） structure of ITO/[MoO3（2.5 nm）/NPB（20 nm）]2/Alq3（50 nm）/LiF（0.8 nm）/Al（120 nm）],the turn-on voltage is reduced to 2.8 V,which is lowered by 0.4 V compared with that of the control device（without MQW structures）,and the driving voltage is 5.6 V,which is reduced by 1 V compared with that of the control device at the 1000 cd/*** this work,the enhancement of the injection and transport ability for holes could reduce the driving voltage for the device with MQW structure,which is attributed not only to the reduced energy barrier between ITO and NPB,but also to the forming charge transfer complex between MoO3 and NPB induced by the interfacial doping effect of MoO3.

A new spectrophotometric method was developed for the determination of aminomethylbenzoic acid （PAMBA） using 7,7,8,8-tetracyanoquinodimethane （TCNQ）. The method was based on the formation of charge transfer （CT） complex of this drug as n-electron donor with the n-acceptor TCNQ. TCNQ was found to react with PAMBA to produce a kind of yellow complex. The CT reaction proceeded quantitatively in pH 8.5 buffer solution. Different variables affecting the reaction were carefully studied and optimized. Under optimal reaction conditions, the stoichiometric ratio of the reaction, maximum absorption wavelength and the value of molar absorptivity were measured to be 1 ： 1, 425 nm, and 1.9 × 10^4 *** ^-***^-1, respectively. Beer＇s law was obeyed in the range of 1- 9 μgomL-1 of PAMBA. The data have been filled to a linear regression equation A= -0.2612＋0.1123c （μgomL^-1）, with a correlation coefficient of 0.9996. The detection limit was 0.4 μg·mL^-1, R,S.D. was less than 1.9%, and average recovery was over 97.6%. The formation of the CT complex was also confirmed by both infrared and 1H NMR measurements. The thermodynamic property, kinetic property and reaction mechanism have also been discussed. The method developed was applied successfully to the determination of the subject drug in its pharmaceutical dosage forms with good precision and accuracy compared to official method revealed by t- and F-tests.

Electrochemical oxidation of BEDT-TTF (bis (ethylenedithio) tetrathiafulvalene) inchloroform/carbon disulfide (3:1) in the presence of Bu4NBr as a supporting electrolyte at lowcurrent density results in the (BEDT-TTF)2Br3H2O crystal. Its composition has been established bychemical analysis (Br, C, H, S), XPS and IR. The temperature dependence of the resistance has beenstudied down to 26K at ambient pressure. This material has weakly metallic behavior above 230K,and becomes a semiconductor below this temperature. The structure of the complex is alsodescribed.

Non-aqueous redox flow batteries, because of larger operating voltage, have attracted considerable at- tention for high-density energy storage applications. However, the study of the anolyte is rather limited compared with the catholyte due to the labile properties of redox mediators at low potentials. Here, we report a new strategy that exploits high concentration organic lithium metal solution as a robust and energetic anolyte. The solution formed by dissolving metallic lithium with biphenyl （BP） in tetraethylene glycol dimethyl ether （TEGDME） presents a redox potential of 0.39V versus Li/Li＋, and a concentration up to 2 M. When coupled with a redox-targeted LiFePO4 catholyte system, the constructed redox flow lithium battery full cell delivers a ceil voltage of 3.0V and presents reasonably good cycling performance.

The kinetics of charge transfer complex(CTC) of 2,3,5,6 tetramethoxyl 1,4 benzoquinone(TMOQ) with two alicyclic N donors,piperidine(PD) and morpholine(ML), in methanol, has been investigated by ultraviolet visible spectroscopy. The transformation leads to the formation of substitution products in solution, which have been isolated and characterized as 2,5 diamino 3,6 dimethoxyl 1,4 benzoquinones by 1H NMR, MS, and elemental analysis. The kinetic results of the formation of products indicate that the rate is first order both with the acceptor and the donor. A mechanism of interaction between TMOQ and PD or ML is discussed.
