α-CD/crown-appended diazophenol for selective sensing of amines

Azophenol dyes having the permethylated cyclodextrin and/or crown moieties have been synthesized. Compound 1 provides critical information on discriminating 1-3° amines with unique color changes. Addition of 1° and 2° amines to 1 shifts the absorbance max

A color version of the Hinsberg test: permethylated cyclodextrin and crown-appended azophenol for highly selective sensing of amines

Azophenol dyes 1-5 having the permethylated cyclodextrin and/or crown moieties have been synthesized. Compounds 1 and 2 provide critical information for discrimination among 1°-3° amines by unique color changes. Addition of 1° and 2° amines to solutions o
