To a three-necked round bottom flask were added 5,5′-(9,9′-spirobi[fluorene]-2,7-diyl)bis(4-(2-ethylhexyl)thiophene-2-carbaldehyde) (220 mg, 0.29 mmol), 1,1-dicyanomethylene-3-indanone (432 mg, 2.2 mmol), chloroform (50 mL), and 0.9 mLpyridine. The mixture was deoxygenated with nitrogen for 30 minand then refluxed for 12 h. After cooling down to room temperature,the mixture was poured into methanol (200 mL) and filtered.The residue was purified by column chromatography on silica gelusing petroleum ether/dichloromethane (1:1) as eluent yield anorange solid (213 mg, 66%). 1H NMR (400 MHz, CDCl3): delta 8.78 (s,2H), 8.68 (d, J 6.9 Hz, 2H), 7.99 (d, J 8.1 Hz, 2H), 7.90 (m, 4H), 7.78 (m, 4H), 7.62 (d, J 8.4 Hz, 4H), 7.41 (t, J 7.5 Hz, 2H), 7.17 (t,J 7.5 Hz, 2H), 6.90 (s, 2H), 6.82 (d, J 7.5 Hz, 2H), 2.38 (d,J 7.2 Hz, 4H), 1.39 (m, 2H), 1.11 (m, 4H), 1.06 (m, 12H), 0.81 (t,J 7.2 Hz, 6H), 0.61 (t, J 7.2 Hz, 6H). 13C NMR (100 MHz, CDCl3): delta 188.78,161.17,157.01, 150.60,148.23, 148.06,142.35,141.37,140.50,138.73, 137.48, 135.75, 135.55, 135.15, 134.12, 130.13, 128.78, 128.70,125.92, 125.42, 124.50, 124.41, 123.29, 121.33, 120,89, 115.07, 114.98,70.38, 66.55, 40.61, 32.88, 32.58, 28.86, 25.82, 23.49, 14.72, 10.89.10.92.
