Abstract
The present invention relates to novel calixarene derivatives having an inclusion activity which are useful for selective transportation of various metal ions, possess a biological activity and a redox activity, and are not only capable of forming conductive or photoconductive electron transfer complexes but also have strong ability of forming complexes and absorbing UV rays. The present invention also relates to intermediates of calixarene derivatives as well as processes for production thereof.
Claims2
A calixarene derivative represented by formula [I] of formula [II]:
- ##STR6## wherein n represents an integer of 3 to 8.
A calixarene derivative represented by formula [XVI]:
- ##STR7## wherein n represents an integer of 3 to 8;
- R.sub.3 represents a hydrogen atom or --COR.sub.5 wherein R.sub.5 represents an alkyl group;
