摘要

Chemical equations presented. A novel bifunctional molecule 1 by a combination of 1,3-alternate calix[4]-crown-5 and triarylborane moieties through alkynyl linkers has been designed and synthesized. Compound 1 shows intense fluorescence with a photoluminescence quantum yield of 0.70 in CH 2Cl2 solution and can serve as a bifunctional luminescent probe for potassium and fluoride ions with high sensitivity and selectivity.
