実験手順
Synthesis of a o-nitrobenzyl PEG-silane of the above formula wherein R3 is H and m=11 was achieved in three steps. First, 5-hydroxy-2-nitrobenzyl alcohol I in 0.3 NaOH was refluxed for four days with undecylenic bromide II (dissolved in CH2Cl2) in the presence of benzyltributylammonium bromide to form 2-nitro-5-(10-undecenyloxy)phenylmethanol III according to the following reaction scheme: ##STR6##
