title: Visual recognition of triamines by phenolphthalein derivatives: consideration of the structure of the colored complex.
abstract: [structure: see text] 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 degrees C and fades with either an increase or decrease in temperature.
