Bright near-infrared chemiluminescent dyes: Phthalhydrazides conjugated with fluorescent BODIPYs
Hirano, Takashi,Li, Guanglei,Yamada, Koji
, (2020)
A series of phthalhydrazides conjugated with NIR fluorescent BODIPY dyes were synthesized (three steps, overall yields 68–83%) and found to show strong NIR chemiluminescence (CL) with maxima in the range of 670–736 nm. One of these showed a CL quantum yield reaching 8.4 times higher than that of luminol. Tuning of the fluorescence band of the BODIPY unit directly leads to a red-shifted CL, developing a strategy for designing NIR chemiluminogens.
Aziridinyl Fluorophores Demonstrate Bright Fluorescence and Superior Photostability by Effectively Inhibiting Twisted Intramolecular Charge Transfer

Replacing conventional dialkylamino substituents with a three-membered aziridine ring in naphthalimide leads to significantly enhanced brightness and photostability by effectively suppressing twisted intramolecular charge transfer formation. This replacement is generalizable in other chemical families of fluorophores, such as coumarin, phthalimide, and nitrobenzoxadiazole dyes. In highly polar fluorophores, we show that aziridinyl dyes even outperform their azetidinyl analogues in aqueous solution. We also proposed one simple mechanism that can explain the vulnerability of quantum yield to hydrogen bond interactions in protonic solvents in various fluorophore families. Such knowledge is a critical step toward developing high-performance fluorophores for advanced fluorescence imaging.

Du, Ya,Hyster, Todd K.,Rovis, Tomislav
, p. 12074 - 12076 (2011/12/14)
An efficient strategy for the oxidative carbonylation of aromatic amides via C-H/N-H activation to form phthalimides using an Rh(iii) catalyst has been developed. The reaction shows a preference for C-H bonds of electron-rich aromatic amides and tolerates a variety of functional groups. The Royal Society of Chemistry 2011.
