Title:
1,8-NAPHTHALIMIDE DERIVATIVE, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/196022
Kind Code:
A1
Abstract:
Disclosed are a 1,8-naphthalimide derivative, a preparation method therefor and a use thereof. The 1,8-naphthalimide derivative of the present invention is relatively easy to prepare, and is an enhanced Cu2+ fluorescent probe, which can detect Cu2+ by means of two wavelengths, and can be especially applied to almost-all-water systems. According to a titration experiment at 392 nm and a blank experiment at 754 nm, the detection limit of the 1,8-naphthalimide derivative of the present invention for Cu2+ is 2.6368×10-7 mol/L and 2.0156×10-7 mol/L respectively, indicating that same can perform quantitative detection for Cu2+ 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 (from a pH of 5.8 to a pH of 6.0, only 0.2 pH units), a good selectivity and a high sensitivity, can be used in almost-all-water systems, and has a bright application prospective.
