FIELD: reversible temperature-sensitive materials, possible use for indication and visual control of temperatures in various technological processes.
SUBSTANCE: composition of reversible thermo-chrome materials is characterized by chemical formula [Ln(C6H13NO)8][Cr(NCS)6], where Ln=La3+, Ce3+, Pr3+, Nd3+, Sm3+, Eu3+, Gd3+, Tb3+, Dy3+, Ho3+, Er3+, Tm3+, Yb3+, Lu3+, C6H13NO=ε-caprolactam.
EFFECT: possible creation of reversible thermo-chrome materials, capable of changing color when heated up to 200-210°C, accessible and easy to produce and comfortable for use in practice.
