中文摘要：

同时含有末端乙氧基醚支链和末端三甲基硅聚乙氧基醚支链的邻苯二甲酰亚胺衍生物1在高氯酸的甲醇溶液中发生光诱导单电子转移（SET）反应,以很高的反应区域选择性和很好的产率得到由末端三甲基硅聚乙氧基醚链环合构成的环状化合物.所有新化合物均经NMR和EI-MS确定其结构.

英文摘要：

Phthalimide derivatives with polyethoxy chain and trimethylsily teminated polyethoxy chian 1 occur photoinduced single electron transfer （SET） cyclization reaction in methanol solvent （containing HClO4）, and could provide cyclocompounds which were participation constituted with the trimethylsily terminated polyethoxy chain in high regioselectivity and good yield. The structures of all new compunds were confirmed by NMR and EI-MS techniques.
