In this manuscript, we have demonstrated an efficient and rapid synthetic strategy for preparation of new fluorene-dendron-hybridized blue light-emitting polymers P1-P7 by the reaction of 9,9 long-chain dialkylated fluorenes M2-M8 with dendronized monomer (M1) under microwave-assisted reaction condition. These fluorene-dendron-hybridized polymers P1-P7 were characterized using different spectroscopic techniques. Furthermore, the optophysical properties of these polymers P1-P7 were studied which revealed that these synthesized polymers P1-P7 have potential to emerge as capable materials in the development of diodes, particularly for blue light emission. In the future, similar approaches would be utilized for preparation of light-emitting polymer composite.
