Abstract

Abstract: The terephthalaldehydes mono-acetal was prepared by the reaction of terephthalaldehyde and ma-lononitrile. The 2-(4-dicyano-vinyl-phenyl)-9-(4-formylphenyl)-2,4,8,10-tetraxaspiro[5.5]undecanes(3) were given through terephthalaldehydes mono-acetal reacting with pentaerythritol and then the hydrolysis occurred in the presence of InBr₃. The calixresorcinarenes 6 was prepared by using terephthalaldehydes mono-acetal and resorcinol as the material. Through compound 6 reacting with compound 3, calixresorcinarene macromolecular dendrimer of 4,6,10,12,16,18,22,24-octahydroxy-2,8,14,20-tetra{(tri(3-phenyl-2,4,8,10-tetraoxaspiro[5.5]undecyl))-(4-(2-(4,6,10,12,16,18,22,24-octahydroxy)calixresorcinarenyl)phenyl)} calixresorcinarene(9) was produced. The product was characterized by IR, ¹H NMR, ¹³C NMR, MS and elemental analysis. The effect factors on the reactions were discussed.
