Visual Recognition of Triamines by Phenolphthalein Derivatives:  Consideration of the Structure of the Colored Complex

A hybrid molecule 1 consisting of phenolphthalein and two crown ether moieties can be used to discriminate the length of linear triamines strictly by color development. The purple color is developed most deeply at −10 °C and fades with either an increase or decrease in temperature.
