A simple complex: ‘on–off–on’ colorimetric and ratiometric fluorescence response towards fluoride ions and its solid state optical properties

A simple 1,1′-bi-2-naphthol (1,1′-BINOL) boron complex has been rationally designed and synthesized, the structure of which was confirmed by single crystal X-ray diffraction analysis. Furthermore, the complex exhibited turn-on fluorescence for fluoride ions with high selectivity and sensitivity. The recognition mechanism for promoting was determined by 1H, 19F and 11B NMR titrations, which indicated that both the photo-induced electron-transfer (PET) and the intramolecular charge transfer (ICT) effects were functionalized. In addition, the complex showed strong solid-state fluorescence, and the emission spectrum and quantum efficiency (ΦF) of the solid powders were also measured.

A trivalent iron ion fluorescent probe compound, and its preparation and use

The invention relates to a ferric fluorescent probe compound as well as a preparation method and application thereof. The ferric fluorescent probe compound has the structure in formula I in the specification. The preparation method comprises the following steps: mixing rhodamine B with anhydrous ethanediamine and refluxing in ethyl alcohol to prepare amide of rhodamine; protecting hydroxyl of binaphthol by chloromethyl methyl ether, reacting with N,N-dimethylformamide under the action of butyl lithium, and removing methyl of methyl ether by hydrochloric acid to obtain binaphthol with aldehyde group; finally refluxing the amide of rhodamine and the binaphthol with aldehyde group in ethyl alcohol and washing to obtain the pure ferric fluorescent probe compound. The probe compound has favorable selectivity and sensitivity for the ferric ions, is simple to treat before sample detection and free of causing toxicity to cells, and is used for detecting the ferric ions in the water environment or the biological cells.

A novel Cr3+ turn-on probe based on naphthalimide and BINOL framework

Naphthalimide and BINOL framework based fluorescent probe NP-B was rationally designed and synthesized. NP-B exhibited 'turn-on' fluorescence for Cr3+ and high selectivity over other metal ions. 1:1 binding mode between NP-B and Cr3+ was proposed and the mode was verified through MALDI-TOF mass spectrum. The detection limit was calculated to be 0.20 μM, which indicated the good sensitivity for Cr3+.

BINAPHTHOL ALDEHYDE DERIVATIVES AND METHOD FOR PREPARING THE SAME

The present invention relates to a binaphthol aldehyde derivative represented by Chemical Formula 1 and a method of preparing the same. The binaphthol aldehyde derivative represented by Chemical Formula 1 enables various kinds of substituent groups to be very efficiently introduced into the hydrogen position of a 2' hydroxy group of 2,2'-binaphthol-3-aldehyde.
