    • Representative Experimental Procedures (a) Preparation of Spiro[fluorene-9,4′-[4H]indeno[3,2-b] thiophene, spiro-FIT) To an AcOH solution (30 mL) of 9-(2-thienylphenyl, fluoren-9-ol (1, 390 mg, 1.14 mmol) was added concentrated HCl (1 mL) at r.t, and the mixture was stirred for 1 h. After the addition of H2O (30 mL, precipitate was collected, washed with H2O, and dissolved in CH2Cl2. The CH2Cl2 solution was washed with 5% aq NaHCO3 and brine. The organic layer was dried over MgSO4 and filtered. The solvents were evaporated, and the residue was purified with column chromatography on SiO2 (EtOAc-hexane, 1:50) to give spiro-FIT (352 mg, 96, as a white solid; mp 167.0-167.3 °C 1H NMR (300 MHz, CDCl3, δ= 6.47 (d, 1 H, J, 4.7 Hz, 6.63 (d, 1 H, J, 7.3 Hz, 6.80 d, 2 H, J, 7.3 Hz
