Disclosed herein are embodiments of a compound that can be used as a supramolecular sensor for determining the presence of analytes (e.g., illicit drugs), and for identifying and/or quantifying the analytes. Also disclosed herein is a parallel synthesis method for making compound embodiments, as well as method embodiments for using the compound embodiments. Array embodiments comprising one or more compound embodiments disclosed herein also are described.

Disclosed are a 1,8-naphthalimide derivative, a preparation method therefor and a use thereof. The 1,8-naphthalimide derivative is easy to prepare, and is an enhanced Cu.sup.2+ fluorescent probe, which can detect Cu.sup.2+ by two wavelengths and be applied to almost-all-water systems. According to atitration experiments and blank experiments at 392 nm and 754 nm, the detection limit of the 1,8-naphthalimide derivative of the present invention for Cu.sup.2+ is 2.636810.sup.7 mol/L and 2.015610.sup.7 mol/L, respectively, indicating that same can perform quantitative detection for Cu.sup.2+ with a high selectivity and a high sensitivity by using two wavelengths. In addition, a pH colorimetric switch based on 1,8-naphthalimide can rapidly and reversibly respond to a pH by means of three ways: a maximum absorption wavelength, absorbance and color change. Same has a narrow switching pH range, a good selectivity and a high sensitivity, can be used in almost-all-water systems.
