Syntheses And Properties Of 1, 6-Methano[10]Annulene Derivatives

This article was composed of two parts. Part one was the syntheses and characterizations of 1,6-methano[10]annulene derivatives. Part two was degradation of organic species in the water by producing porous glass which has the photocatalysis.Part one was the syntheses and characterizations of 1,6-methano[10] annulene derivatives. First the 3-bromo-1,6-methano[10]annulene was prepared by 10Ï€ electrocyclic reaction from starting material of 1,6-diformyl-1,3,5-cycloheptatriene by 5 steps. And the 3,3'-Bi-1,6-methano [10]annulene was synthsized by base-induced coupling of 3-bromo-1,6-methano[10]annulene. Then additional compound of 1,6-methano[10] annulene derivative with C₆₀ was prepared too. The products was charactered by ¹H NMR,¹³C NMR and Ms spectrums.Recently, study on wastewater treatment by using TiO₂ has great development. In this area TiO₂ was loaded on carrier or suspended to get better catalysis efficiency. But the most of carriers were inorganic materials. It is limited to be used as photocatalyst for low loading amount of TiO₂ or low using of light. Porous glass has increased specific surface area to load more TiO₂, so that it can get better catalysis efficiency. So, our work is to degrade organic species in the water by producing a kind of porous glass, which has the photocatalysis. By adjusting the ratio of silica gel, glass powder and sodium bicarbonate, we produced spheroplast. And through...
