摘要
合成了下缘硫、硒杂杯[4]芳烃,然后与杯芳烃片段2,6-二(溴甲基)-4-甲氧基-甲苯在NaH存在条件下缩合得到硫、硒杂多杯[4]芳烃5a和5b.离子萃取实验表明硫、硒杂多杯[4]芳烃显著增加了对Ag+和Hg2+重金属离子的萃取效果.
Thia (selena) calix[4]arenes were condensed with a calixarene segment, 2,6-bis (bromomethyl)- 4-methylanisole, to afford multi-calix[4]arenes 5a and 5b in presence of sodium hydride. The complexation abilities of the multi-calix[4]arenes with Ag+ and Hg2+ were superior to those of their monomers.
