with the PM3calculation is most closely related with the fluorescence characteristics. Using these parameters, the fluorescent 4,7-disubstituted benzofurazancompounds were classified into two groups, and the maximum excitation and emission wavelengths were different between these two groups. These relationships indicated that the fluorescence characteristics of 4,7-disubstituted benzofurazan compounds
A novel activatable fluorescentprobe for hypochlorous acid (HOCl) imaging, has been developed based on HOCl-triggered aldehyde recovery reaction. This probe features with a long emission wavelength because of the use of intramolecular charge transfer (ICT) effect in the fluorophore. Moreover, this probe displayed ultrafast response (within 1 s), good selectivity and high sensitivity (detection limit
Terpyridine/benzofurazan conjugation results in a new hybrid fluorophore of the colorimetric sensing ability for Fe2+ and fluorimetric sensing ability for XII group cations. The improved emission properties and cell imaging ability imply it is a suitable platform to construct a fluorescent sensor for metal imaging in biological systems.
萜吡啶/苯并呋喃共轭产生了一种新的混合荧光团,它对 Fe2+ 具有比色感应能力,对 XII 族阳离子具有荧光感应能力。其发射特性和细胞成像能力的改善意味着它是构建用于生物系统中金属成像的荧光传感器的合适平台。
