A novel flavone-based fluorescent probe for relay recognition of HSO3− and Al3+
摘要:
In this work, a new flavone-based fluorescent probe 3-hydroxy-3'-formylflavone (3HFF) was designed to achieve highly selective relay recognition of HSO3- and Al3+ in DMSO-H2O (2:8, v/v) solution. 3HFF displayed a highly selective response to HSO3- with a green fluorescence appearing at 524 nm. Moreover, the in situ generated 3HFF + HSO3- system demonstrated eminent relay recognition capability for Al3+ with a blue fluorescence appearing at 453 nm by the formation of a 1:1 complex between 3HFF and Al3+ in DMSO-H2O (2:8, v/v) solution. However, only slight change was observed in emission intensity with addition of Al3+ to 3HFF, and indicated HSO3- was essential for the sensing of Al3+. This work achieves the detection of HSO3- and Al3+ by only one probe and provides another example for this rare combination (anion/metal). (C) 2015 Elsevier B.V. All rights reserved.

The dizinc(II) complexes of L were used for the recognition of anions by fluorescence spectroscopy (L is a heteroditopic hexaazamacrocycle with two diethylenetriamine coordination heads with 2-methylpyridyl and dansylamido ethyl arms, and m-xylyl spacers). The protonation of L and stabilityconstants of its zinc(II) complexes were determined in aqueous solution, at 298.2 ± 0.1 K and I = 0.10 ± 0.01
所述dizinc(II)配合物的大号被用于通过荧光光谱法识别阴离子(大号是heteroditopic hexaazamacrocycle与2-甲基吡啶基二乙烯三胺2协调头和dansylamido乙基臂,和米-二甲苯间隔物)。在水溶液中测定了L的质子化及其锌(II)配合物的稳定常数,在KNO 3中为298.2±0.1 K和I = 0.10±0.01M 。在2:1 Zn 2+ / L在比例上,双核复合物显然占主导地位。单独的配体不会随pH值的增加而显示荧光变化,但是在Zn 2+的存在下,发射在pH≥7.5时达到最大值,此时95%的配体为双核络合物形式。发射与[Zn 2 H -1 L ] 3+物种形成同时出现,这表明后者的络合物对应于金属促进的丹磺酰胺NH的去质子化。[Zn 2 H -1 L ] 3+络合物用于识别在pH 7.5和2mM PIPPS缓冲于298.2 K的水溶液中的磷酸根和多磷
Multichannel-Emissive V-Shaped Boryl-BODIPY Dyads: Synthesis, Structure, and Remarkably Diverse Response toward Fluoride
vastly different response behaviors. When fluoride binds to the tricoordinate borane center, dyad 1 shows gradual quenching of its BODIPY-dominated emission due to the ceasing of the (borane to BODIPY) EET process. Dyad 2 shows a ratiometricfluorescenceresponse for fluoride ions. Dyad 3 forms fluoride-induced nanoaggregates that result in fast and effective quenching of its fluorescence intensity just
