The first mesogenic derivative of boron difluoride β-diketonate

Boron difluoride β-diketonate exhibiting liquid crystalline as well as photoluminescence properties was prepared for the first time. It is the promising material for creating supramolecular organized luminescent media. Pleiades Publishing, Inc., 2006.

Organic Thermometers Based on Aggregation of Difluoroboron β-Diketonate Chromophores

We report several novel thermometers resulting from the temperature-induced aggregation of difluoroboron β-diketonate chromophores. These thermometers exhibit a much wider temperature-dependent fluorescence emission from 445 to 592 nm along with the color change from blue to red in a dilute chloroform solution. Spectroscopy measurements and theoretical calculations confirm that the thermochromic luminescence originates from the reversible change in the noncovalent intermolecular interactions and the abrupt volume shrinkage of the solvent at its melting point. The present work provides a new strategy for rationally designing high-performance thermometers having a wide emission property.

A compound according to Formula (I) or a pharmaceutically acceptable salt and/or solvate thereof, wherein X1 and X2 are each independently 18F or 19F; R1 and R2 are each independently alkyl, amine, perfluoroalkyl, alkenyl, alkynyl, aryl, or aralkenyl; and R3 is H, halo, alkyl, alkyl ester, alkenyl, alkynyl, aryl, or aralkenyl; or wherein: R1 and R3 or R2 and R3 join to form a 6-membered cycloalkyl or heterocyclyl; or R1 and R3, R2 and R3, or R1, R2, and R3 join to form a substituted or unsubstituted polycyclic ring, wherein the polycyclic ring comprises fused cycloalkyl, heterocycloalkyl, aryl, or heteroaryl rings.

Triphenylamine-modified difluoroboron dibenzoylmethane derivatives: Synthesis, photophysical and electrochemical properties

Two new triphenylamine functionalized difluoroboron (BF2) β-diketonate complexes, one asymmetrical 2 and the other symmetrical 3, were synthesized and fully characterized. The effects of the triphenylamine substituent on the photoluminescence,

Blue thermally activated delayed fluorescence from a biphenyl difluoroboron β-diketonate

Optical properties of biphenyl difluoroboron β-diketonates were studied in poly(lactic acid) (PLA) blends. Increased conjugation lowered the emission energy, decreased the singlet-triplet energy gap and yielded blue thermally activated delayed fluorescence (TADF). The properties of these biphenyl dyes may inform organic light emitting diode (OLED) and bioimaging agent design.

A simple approach to aggregation-induced emission in difluoroboron dibenzoylmethane derivatives

The first example of an AIE active BF2dbm derivative with a single dimethylamino group connecting to the phenyl ring was revealed. It also showed capability of sensing HCl gas both in solution and in the solid state.

White light emission from a single component system: Remarkable concentration effects on the fluorescence of 1,3-diaroylmethanatoboron difluoride

Concentration effects on the fluorescence (FL) emission of 1,3-dibenzoylmethanatoboron difluoride (1aBF2) and its diisopropyl derivative (1bBF2) in KBr and CH2Cl2 were investigated. Powder samples of 1aBF2 and 1bBF2 in KBr exhibit yellow and white FL emissions, respectively, whose intensities and wavelengths are not significantly affected by concentration. In contrast, remarkable concentration effects on FL properties of these compounds in CH 2Cl2 solutions were observed. Increases in the concentrations of 1aBF2 and 1bBF2 from 1 × 10 -7 to ca. 2 × 10-1 M lead to dramatic changes in the FL colors from blue (398 and 411 nm, respectively) to yellow (548 and 558 nm) via white. Careful analysis of the FL spectra, involving lifetime determinations and wave deconvolutions, reveals that emissions from 1BF2 involve two FL domains, corresponding to an excited monomer and an excimer, and that concentration increases promote a continuous change from the former to the latter major FL domain. Thus, white FL of 1aBF2 and 1bBF2 is achieved by modulation of the dual FL of the excited monomer (blue) and excimer (yellow). These findings indicate that 1,3-diaroylmethanatoboron difluoride (1BF2) represents a new white emitting material that has advantageous features which arise from the fact that it is an easily prepared, low molecular weight, single component system not containing a heavy metal atom.

Selective addition of organolithium reagents to BF2-chelates of β-ketoesters

A short, mild, and highly chemoselective addition of organolithium reagents to a BF2 complex of 3-oxopropanoates has been developed. The methodology allows straightforward preparation of various 1,3-dioxa-BF 2 complexes and subsequently leads to the formation of 1,3-diketones starting from the corresponding 3-oxopropanoates.

A new and a convenient route to enaminones and pyrazoles

A new method has been developed for the regioselective preparation of enaminones and pyrazoles from 1,3-diketonatoboron difluorides. The reactions proceed smoothly under mild reaction conditions, producing enaminones and pyrazoles in high yields.
