The nanoscale titania coated silica was prepared via a two-step precipitating approach, where the nanoscale silica nuclei were first prepared by passing an aque
Twelve of the title compounds were synthesized. Their structures were identified by means of IR, EA, 1H NMR and MS. The IR spectra clearly show that the absorpt
The title copolymer(PDEBO) was synthesized. The thermal characteristics of the polymer were determined by means of DSC and TGA, revealing that the polymer has a
(2,4-C7H11)2Yb*DME was synthesized by the reaction of YbCl3 with K(2,4-C7H11)(2,4-dimethylpentadienyl potassium), and the single crystal X-ray diffraction showe
