ABSTRACT:
Temperature probes are provided comprising a porous or permeable substrate into which is absorbed at least at the surface a diyne monomer. The absorption is achieved by employing a solution of the diyne monomer in a solvent which is transported by the solid substrate. After impregnation of the substrate, the diyne is polymerized to provide a blue product, which upon being heated above a transition temperature turns to red. Various substrates and devices may be employed for a variety of situations requiring a determination of the occurrence of a particular minimum temperature.
