Abstract
The solid thermochromism of metallophthalein was studied in the organic phase: 3,3-bis[bis(biscarboxymethyl)aminomethyl]phthalein derivatives, bivalent metal ions, and 3- or 4-substituted pyridines in polymer matrices. An intensive reversible color development (colorless⇄blue) by the application of heat was found for the nickel(II) chelate of cresolphthalein with 3-(N-alkyl)carbamoylpyridine in polar aprotic matrices. The bleaching rate in the matrices was strongly dependent on humidity. Thus, the cycle (color development, fixing, and bleaching processes) was controllable and repeatable.
