A specific Cu2+ sensor, 2-amino-3-(BODIPYmethyleneamino)maleonitrile (BDM), was established by a simple dehydration between BODIPY and diaminomaleonitrile. Cu2+ could be recognized by BDM over other competing metal ions in acetonitri

Photophysical properties of BODIPY dyes containing acetyl acetone and benzoyl acetone BF2 unit as an electron accepting substituent at beta position linked via double bond have been investigated using a wide range of solvents of different polarities. The substitution effect at beta position of the BODIPY dyes on their absorption, emission and quantum yield of fluorescence have been the aim of present study. For the synthesized BODIPY dyes fluorescence quantum yields and lifetimes show very sharp decrease with an increase in the solvent polarity, suggesting the involvement of highly polar ICT state de-excitation mechanism along with the local excitation process. The polarity dependent changes in average fluorescence life time and quantum yield values rationalize the formation of ICT states.

A new red-fluorescent BODIPY derivative is designed and synthesized, which is configured by attaching an electron-withdrawing unit 2-dicyanomethylene-3-cyano-4,5,5-trimethyl-2,5-dihydrofuran (TCF). By virtue of the strong electron-accepting nature of TCF unit, the compound BT exhibits a large red-shift both in absorption and emission. In contrast to parent BODIPY, the absorption shifted about 90?nm. And the emission maximum shifted to red region with the peak centered around 620?nm. The CIE coordinate and fluorescence decay data uncovered its emission character. Theoretical calculation of BT confirmed that the electron density was altered dramatically by TCF and lowered the energy gap between ground state. The character of HOMO/LUMO distribution is well in agreement with that of experimental value.

Hypochlorite plays a significant role in various physiological and pathological processes; however, its role is still less clear than the role of other reactive oxygen species. Herein, we report an ultrafast responsive (a detection limit as low as 7.5 nM. The probe was compatible in a wide pH range of 4-13. More importantly, experiments in live cells showed that the probe could penetrate the cell membrane easily and was capable of imaging endogenous and exogenous hypochlorite specifically with a fast response.

A fluorescent probe composed of BODIPY and 2,4-dinitrophenylhydrazine was designed for the detection of ClO?. The oxidizing reaction between probe and ClO? resulted in a distinct fluorescence enhancement together with a color variation from pink to orange. This probe showed excellent selectivity to ClO? among various ions including common reactive oxygen species and high sensitivity with a detection limit of 228 nM. A fast response (7 min) was observed, which made the probe a promising method in real-time detection. Furthermore, this probe was successfully applied to monitor ClO? in real-life water and living cells.
Emission behavior of perimidine attached BODIPY and its response to acid/base

, p. 131 - 138 (2017)
A BODIPY based with perimidine attached derivative was developed and characterized. It was efficiently synthesized by condensation between aldehyde sited at β-position of BODIPY and 1,8-diamino-naphthalene. Owing to the electron-donor effect of N in heterocycle, emission was quenched completely. Upon protonation of N, the solution exhibited dramatic emission enhancement with emission peak locating at 510?nm, which is estimated to be 275-fold of initial emission. With OH? addition, it could be reverted to the emission to non-emisison state again and establish a fluorescence switch. The underlying mechanism of fluorescence “off-on” is based on the intramolecular PET, which was attested by quantum chemistry calculation approach.
