Notes:
Trimethyl- and tert-butyldimethylsilylcellulose were esterified with cinnamic acid, 4-nitrocinnamic acid, 4-(hexyloxy)cinnamic acid, 4-(hexadecyloxy)cinnamic acid and N-cinnamoyl-11-aminoundecanoic acid yielding photosensitive comb-like cellulose derivatives. The UV-irradiation of solid films of tert-butyldimethylsilylcellulose cinnamate, trimethylsilylcellulose 4-nitrocinnamate and tert-butyldimethylsilylcellulose-4-hexyloxycinnamate were performed and the decrease of the absorption maxima was correlated with E/Z isomerisation and [2 + 2]-cycloaddition. A possible application of the described photoreactive cellulose esters in the area of membrane technology is discussed.
