Abstract

Abstract : C 3 -Symmetric thermally stable twisted phenothiazine-based organic salt is recognised as a mechano-/thermo-fluorochromic material and used as reusable molecular thermometer to detect the temperature range of 130–170 °C. Abstract : C 3 -Symmetric triaminoguanidinium chloride is condensed with N -pentylphenothiazine carboxaldehyde to realise a thermally stable twisted organic salt on a gram scale. It appears as a nonmetallic economic salt having an integrated propeller shape with three tub-like cores and displays efficient reversible mechano- and thermo-fluorochromic behaviour. Unlike previous reports, the designed fluorescent, colorimetric thermometer works over a higher temperature range of 130–170 °C with five distinct colour variations.
