Abstract
A fluorescent compound for acid detection is strongly emissive in the solid state and can aggregate in the presence of an acid. As such, a fluorescent intensity emitted from the compound can be enhanced from an original intensity level in the presence of an acid. The fluorescent compound can emit an enhanced fluorescent intensity in the presence of an ultra-low acid concentration, for example, a concentration of at least about 10M.
