摘要

The synthesis and photoinduced deprotection reaction of calix[4]resorcinarene derivatives with pendant acetal moieties were examined.C-methyl[(methoxymethylcarbonyl)oxy]calix[4]resorcinarene (CRA-Acetal) and C-4-hydroxy-phenyl[(methoxymethylcarbonyl)oxy]calix[4]resorcinarene (CRA_(ph)-Acetal) were prepared from C-methylcalix[4]resor-cinarene (CRA) and C-4-hydroxyphenylcalix[4]resorcinarene (CRA_(ph)).The synthesized CRA-Acetal and CRA_(ph)-Acetal had good solubilities,good film-forming properties,and high thermal stabilities.The photoinduced deprotection reaction of CRA-Acetal and CRA_(ph)-Acetal was examined in the presence of bis[4-(diphenylsulfonio)phenyl]sulfide (DPSP) as a photo-acid generator in the film state upon UV irradiation.It was found that the deprotection reaction of acetal groups of CRA-Acetal and CRA_(ph)-Acetal proceeded smoothly without further heating to produce the corresponding calixarene derivatives,CRA-COOH and CRA_(ph)-COOH with carboxylic acid groups.
