Highly selective ion probe for Al3+ based on Au(i)⋯Au(i) interactions in a bis-alkynyl calix[4]arene Au(i) isocyanide scaffold†
Abstract
A bis-alkynyl calix[4]arene Au(I) isocyanide complex has been synthesized and demonstrated to be a selective ion probe for Al3+ based on Au(I)⋯Au(I) interactions.
