A laterally π-expanded fluorone dye as an efficient near infrared fluorophore

The synthesis and photophysical properties of new dibenzo[ b , i ]fluorone dye frameworks (BX and FBX) are described. Both BX and FBX display near-infrared sharp absorption and emission upon the addition of base due to the achievement of efficient π-conjugation based on the small bond alternation st...

Zusammenfassung:The synthesis and photophysical properties of new dibenzo[ b , i ]fluorone dye frameworks (BX and FBX) are described. Both BX and FBX display near-infrared sharp absorption and emission upon the addition of base due to the achievement of efficient π-conjugation based on the small bond alternation strategy. FBX in DMSO displays remarkably red-shifted and sharp absorption and fluorescence bands at 817 nm and 853 nm, respectively.
