Amao, Yukata published the artcileNovel optical CO2 sensing material: pH indicator immobilized in fluorine-containing poly(aryl ether ketone) films, Recommanded Product: 3,3-Bis(4-hydroxynaphthalen-1-yl)isobenzofuran-1(3H)-one, the publication is Sensor Letters (2005), 3(2), 168-173, database is CAplus.

New F-containing poly(aryl ether ketone)s (8F-PEKEK(Ar); Ar: 2-2-bis(4-hydroxyphenyl)-1,1,1,3,3,3-hexafluoropropane (6FBA), 2,2-bis(4-hydroxyphenyl)propane (BA), 2-(4-hydroxyphenyl)-2-(3-hydroxyphenyl)propane (3,4′-BA) or 9,9′-bis(4-hydroxyphenyl)fluorine (HF)) were synthesized and applied to the matrix of optical CO2 sensor based on the overlay of the CO2 induced absorbance change of pH indicator dye α-naphtholphthalein with the fluorescence of tetraphenylporphyrin (TPP) was developed. The observed luminescence intensity from TPP at 655 nm increased with increasing the CO2 concentration The ratio I100/I0 values of the sensing films consisting of α-naphtholphthalein in 8F-PEKEKs layer and TPP in polystyrene layer, where I0 and I100 represent the detected luminescence intensities from a layer exposed to 100% Ar and 100% CO2, resp., that the sensitivity of the sensor, are >3.6. The response and recovery times of the sensing films consisting of α-naphtholphthalein in 8F-PEKEKs layer and TPP in polystyrene layer were <8.6 s for switching from Ar to CO2, and for switching from CO2 to Ar. The signal changes were fully reversible and no hysteresis was observed during the measurements. The highly sensitive and fast responsible optical CO2 sensor based on fluorescence intensity changes of TPP due to the absorption change of α-naphtholphthalein in 8F-PEKEKs layer with CO2 was achieved.
