The invention is directed to latent reactive and polymerizable derivatives of fluorescent stilbene-based compounds. The compounds can be used to provide articles with a fluorescence property, such as medical devices (e.g., catheters). The fluorescent compounds can be used in association with polymers, or can be incorporated into polymers, and the polymers used in a coating composition on the article surface. The compounds allow for visual or machine inspection of coating properties such as uniformity of coverage.

The present invention relates to an amino acid-based compound for detecting carbon dioxide, and to a carbon dioxide chemical sensor and a carbon dioxide detection method using the compound, wherein the compound having selectivity with respect to carbon dioxide exhibits a high selectivity to carbon dioxide and thus may detect carbon dioxide of a very low concentration, exhibits excellent light-absorbing or fluorescent characteristics, and, in particular, may achieve an effect of detecting carbon dioxide in real time.
