FLUOROGENIC PARA-TERT-BUTYLCALIX4ARENE PYRENEAMIDE CARBOXYLIC ACID DERIVATIVES, THEIR PREPARATION AND USE THEREOF

摘要

The present invention provides novel water-soluble that it expressed by the formula (1) to selectively sensitive to calcium ions, para -tert - butyl knife Riggs [4] arene -carboxylic acid amide fluorescent pyrene derivatives , relates to a method of manufacturing the same , and their use , which body growth , maintenance , reproduction and essential nutrients, calcium metal as well as be able to extract a fluorescent substance is introduced there is a specific metal ion and which can be used to advantage when a chemical sensor due to changes made to the fluorescent complexes ; st32:. che xmlns: st32 = "http : //alexandria.fairviewresearch.com/ns/st32/ " /st32: che
