제목 Synthesis and photophysical properties of polybenzothiadiazole for fluorescent anion sensing
초록 Recently, fluorene-based π-conjugated polymers have emerged as a very promising candidate for polymer light-emitting diodes (PLEDs) due to their combined desirable properties, such as high fluorescence quantum yield and hole-transporting properties. We designed and synthesized the polybenzothiadiazole through Suzuki cross-coupling between 4,7-dibromo-2,1,3-benzothiadiazole and 9,9-dihexylfluorene-2,7-(bistrimethyleneborate). The obtained polymer was characterized with NMR, IR, GPC, UV/vis and fluorescence spectroscopy. The polymer, emitting intense green fluorescence, has higher binding capacity for fluoride anion (F-) than thoese of other anions.
