1,4-Bis(phenylethynyl)benzene is a fluorescent derivative of the molecule with a skeleton that can be used to create polymers with fluorescence properties. The fluorescent derivative emits light at approximately 350 nm when excited by ultraviolet radiation. It has been shown that this molecule is able to form polymers that are sensitive to various gases and vapors. The polymer film will fluoresce in the presence of an optical sensor, which can be used as a sensor for carbon dioxide, ammonia, or sulfur hexafluoride. 1,4-Bis(phenylethynyl)benzene is also able to absorb ultraviolet radiation of wavelengths between 200 and 400 nm and emit light at longer wavelengths.
