I'm developing a sensor to detect organic vapors that has to work at a temperature range between 60 - 80 ºC. The chemical dyes I've used so far such as Reichardts Dye, Red Nile or Oil Red show a spectral shift in presence of this kind of vapors, but they are strongly influenced by temperature.
Any alternative?
It depends of the magnitude of changes due to temperature.
Please read the attached paper.

Pruebe con la familia del negro de Eriocromo T. Pero No sé SUS Características Temperatura contra.
All of sensor response are depends to temperature, because they work based on equilibrium or kinetic methods, and those are temperature dependence. Therefore, a suitable correction factor should be evaluated to can work in different temperature.
Las ftalocianinas (algunas de ellas son comerciales) podrían ser la solución. Hay mucha bibliografía en JCR
As mentioned by Ali A. Ensafi, it will be difficult to find such compounds, as sorption equilibria, interaction kinetics etc are strongly temperature dependent. Even metal oxide sensor, which are heated to high temperatures above 150-200°C, have some ambient temperature dependency.
