We have examined the synthesis of cyclic oligomers with pendant norbornadiene (NBD) moieties based on the calixarenes [p-tert-butylcalix[8]arene (BCA), p-methylcalix[6]arene (MCA), )calix[4]resorcinarene (CRA), 2,8,14,20-tetra-decylcalix]4]resorcinarene (CRA 1 0 ), and 2,8,14,20-tetrakis(p-hydroxyphenyl)calix[4]resorcinarene (CRA p h )]. The photochemical valence isomerization of the obtained calixarene
我们已经研究了基于杯芳烃 [对叔丁基杯[8] 芳烃 (BCA)、对甲基杯[6] 芳烃 (MCA)、杯[4] 间苯二酚的具有侧降冰片二烯 (NBD) 部分的环状低聚物的合成(CRA)、2,8,14,20-四癸基杯]4]间苯二酚 (CRA 1 0 ) 和 2,8,14,20-四(对羟基苯基)杯[4] 间苯二酚 (CRA ph )] . 得到的含有 NBD 部分的杯芳烃衍生物的光化学价异构化进行得非常顺利,得到相应的四环 (QC) 部分,并且发现光异构化前后的折射率变化很大(An's = 0.028-0.061)。
