The invention relates to a probe used for detecting diethylstilbestrol, and in particular to an organic compound based on gallocyanine and application of the organic compound. The structure of the compound is shown as the formula I; the compound is taken as the probe detecting diethylstilbestrol. According to the invention, when diethylstilbestrol exists, remarkable change occurs to corresponding fluorescent intensity; the compound can be used for detection of diethylstilbestrol, greatly reduces interference of external detecting conditions, and improves detection precision; besides, remarkable change occurs to ultraviolet absorption when diethylstilbestrol exists; an ultraviolet spectrophotometer and naked eyes can be adopted for detection at the same time; the probe has the advantages that the probe is simple, convenient and quick to operate, visible in naked eye, low in cost, and wide in application range.
