By Kyohei Sezukuri, Mitsuharu Suzuki, Hironobu Hayashi, Daiki Kuzuhara, Naoki Aratani and Hiroko Yamada


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
