Compound containing triaryl boron skeleton, and preparation method and application thereof

The invention discloses a compound containing a triaryl boron skeleton, and a preparation method and application thereof. The compound can be used as a self-reference silver ion fluorescent probe in a liquid organic solvent and an organic solvent-water mixed solution. After the compound is independently dispersed in the liquid solvent, the luminescent color and intensity of a system are changed along with the concentration of the measured Ag, and the fluorescent quantum efficiency is always high. A fluorescent device is low in cost, high in shape plasticity, high in sensitivity and capable of self-reference property. (Shown in the description).

Three aryl boron fluorescent compound and its preparation and use

The invention discloses a series of triaryl boron fluorescent compounds and a nanometer aquagel fluorescent sulfydryl probe based on the triaryl boron fluorescent compounds. The triaryl boron fluorescent compounds are characterized by excellent selectivity to sulfydryl compounds, so that the triaryl boron fluorescent compounds can be used as fluorescent probes for detecting sulfydryl compounds in an organic solution or an organic-water mixed solution. The nanometer aquagel fluorescent sulfydryl probes based on the triaryl boron fluorescent compound can not only be used for detecting the sulfydryl compounds in an aqueous solution or a buffer solution, but also be used in sulfydryl compound single-photon or dual-photon fluorescent imaging in cells because of the availability of self-entering into the cells. The fluorescent probe has the advantages of high sensibility, fast response speed, good specificity, low biotoxicity, wide response range and the like.

Two photon absorption energy transfer in the light-harvesting complex of photosystem II (LHC-II) modified with organic boron dye

The plant light-harvesting complexes of photosystem II (LHC-II) play important roles in collecting solar energy and transferring the energy to the reaction centers of photosystems I and II. A two photon absorption compound, 4-(bromomethyl)-N-(4-(dimesitylboryl)phenyl)-N-phenylaniline (DMDP-CH 2Br), was synthesized and covalently linked to the LHC-II in formation of a LHC-II-dye complex, which still maintained the biological activity of LHC-II system. Under irradiation with femtosecond laser pulses at 754 nm, the LHC-II-dye complex can absorb two photons of the laser light effectively compared with the wild type LHC-II. The absorbed excitation energy is then transferred to chlorophyll a with an obvious fluorescence enhancement. The results may be interesting and give potentials for developing hybrid photosystems.

Triarylborane-appended new triad and tetrad: Chromogenic and fluorogenic anion recognition

Facile synthesis of triad 3 and tetrad 4 incorporating -B(Mes)2 (Mes = mesityl (2,4,6-trimethylphenyl)), boron dipyrromethene (BODIPY), and triphenylamine is reported. Introduction of two dissimilar acceptors (triarylborane and BODIPY) on a single donor resulted in two distinct intramolecular charge transfer processes (amine-to-borane and amine-to-BODIPY). The absorption and emission properties of the new triad and tetrad are highly dependent on individual building units. The nature of electronic communication among the individual fluorophore units has been comprehensively investigated and compared with building units. Compounds 3 and 4 showed chromogenic and fluorogenic responses for small anions such as fluoride and cyanide.
