▎ 摘　　要

NOVELTY - A graphene-containing compound (I), is new. USE - New graphene-containing compound used as fluorescent probe in preparation of test paper fluorescence sensor for detecting nitroaromatic hydrocarbon explosives (all claimed). ADVANTAGE - The compound (I) has improved non-luminescent properties, and successfully realized the sensitive and visual detection of nitroaromatics explosives. The compound (I) enables reliable detection method for rapid, economical, accurate and visual detection of the content of nitroaromatics. DETAILED DESCRIPTION - A graphene-containing compound of formula (I), is new. A = group of formula (i);and B' = group of formula (ii). INDEPENDENT CLAIMS are included for the following: (1) preparation of the compound (I); (2) use of the compound (I) in detection of nitroaromatic hydrocarbon explosives; and (3) test paper fluorescence sensor, which is prepared by dissolving composite fluorescent probe in a solvent to obtain a probe solution, taking out a test paper and soaking in the probe solution, taking out and drying.
