Water-Soluble BODIPY Derivatives

Organic Letters, 2009
New, water-soluble BODIPY dyes have been readily obtained from various BODIPY cores by reactions involving the introduction of novel sulfonated peptide chains by either coupling or substitution to give dimethylpropargylamine derivatives subsequently quaternized by reaction with propanesultone.

Robust synthesis of F-BODIPYs

Organic & Biomolecular Chemistry, 2016
A protocol is established for the high-yielding synthesis of F-BODIPYs involving non-anhydrous reagents and not requiring precautions to exclude moisture.

Sulfur‐Bridged BODIPY DYEmers

Chemistry – A European Journal, 2013
AbstractReactions of BODIPY monomers with sulfur nucleophiles and electrophiles result in the formation of new BODIPY dimers. Mono‐ and disulfur bridges are established, and the new dyestuff molecules were studied with respect to their structural, optical, and electrochemical properties.

Synthesis of diastereoisomeric BODIPY: An attempt on the resolution of axially chiral BODIPYs

AIP Conference Proceedings, 2021
This article provides efforts on a resolution of axially chiral BODIPYs (Ax*-BODIPY) towards Boron’s chiral utilization. Simply by generating the second chiral center on the dipyrromethene ring over the B-F substitution reaction, the Ax*-BODIPY will then turn to plausibly separable diastereoisomers, a column chromatographically separable molecule.

Solvatochromism of BODIPY-Schiff Dye

The Journal of Physical Chemistry B, 2014
A boron-dipyrrin chromophore connected with an o-hydroxyaryl aldimine by a diazo bridge (BODIPY-Schiff dye) has been developed. The photophysical properties of the BODIPY-Schiff dye have been investigated with UV, steady-state, and time-resolved fluorimetry.

Meso enamine substituted BODIPYs

Chemical Communications, 2014
Different enamines were introduced at the meso position of the BODIPY by catalyst free oxidation of tert-amines and in situ cross coupling with 8-chloro BODIPY. The reaction conditions were optimized to achieve better yields. The reaction works well with aliphatic tert-amines bearing an N-(CH-CH-) backbone.

Fluorescent indicators based on BODIPY

Chem. Soc. Rev., 2012
This critical review covers the advances made using the 4-bora-3a,4a-diaza-s-indacene (BODIPY) scaffold as a fluorophore in the design, synthesis and application of fluorescent indicators for pH, metal ions, anions, biomolecules, reactive oxygen species, reactive nitrogen species, redox potential, chemical reactions and various physical phenomena.

Oxidation of 2-amino-substituted BODIPYs providing pyrazine-fused BODIPY trimers

Chem. Commun., 2014
One-step oxidation of β-amino BODIPYs provides BODIPY trimers with a pyrazine-fused BODIPY dimer structure, which exhibit strong NIR absorption bands.

A BODIPY analogue from the tautomerization of sodium 3-oxide BODIPY

Chinese Chemical Letters, 2015
Abstract The introduction of hydroxy group to the 3- or 5-position of 4,4-difluoro-4-bora-3a,4a-diazaindacene (BODIPY) results in unexpected tautomerization to BDPONa with interesting structural and photophysical properties. The core of BDPONa is an anion with sodium cation as counter-ion. BDPONa displays strong fluorescence in organic solvents.

Investigation of B-F substitution on BODIPY and aza-BODIPY dyes: Development of B-O and B-C BODIPYs

Dyes and Pigments, 2019
Abstract Among the wide-range of chemical reactions that can be performed on BODIPYs, attack on the boron atom opens the door to the synthesis of numerous more or less complex fluorophores. Moreover, the modifications that occur preserve the unique photo-physical properties of while improving their quantum yield, stability and solubility either in ...
