Abstract
Hydrogen bonding between carboxylic acid and amide groups was demonstrated for a series of amides called [n]-semirubins consisting of a dipyrrinone attached to the end of an n- carbon alkanoic acid. Such hydrogen bonding is more effective than the alternative amide to amide or acid to acid types for all of the semirubins studied: n= 1, 3–7, 10 and 20. As determined by 1H NMR and vapour pressure osmometry,[n]-semirubins, where n= 5–20, ...
