A new method was developed using ultrasonic irradiation to synthesize poly(2-methoxy-5-butoxy) phenylene vinylene from p-methoxy phenol (MOPh) and CH3 (CH2)3Br.
The Olenekian Stage of the Lower Triassic is named from the Boreal Realm, but the stage has never been properly defined, nor has it been applied in the low-lati
New electron donors with hydroxyl groups were synthesized and characterized spectroscopically.Their redox potentials were determined with cyclic voltammetry, an
A complete potential energy surface for the CHClFOH system was calculated at the G3(MP2) level.The calculations reveal that the four-center 1,2-HX (X=F, Cl) eli
The UV-Vis spectra of THPPH2 in CTAB micelles at pH7.2 and pH11.0 were analyzed to study the effect of micellar environments on the aggregation behaviors of thi
A novel polymeric complex [La(bipyN2O2)(TFA)3]n(TFA= trifluoroacetylacetone) was prepared.The X-ray structure analysis revealed that the complex has an infinite
A new flavonoid, namely pinnatifine Ⅰ (1), was isolated from the leaves of Crataegus pinnatifida Bge.var.major N.E.Br..Its structure was elucidated by spectros
A combined EDTA-citrate complexing method was developed for the easy preparation of mixed oxygen-ionic and electronic conducting dense ceramic membrane for oxyg
