실험 절차

2,7-Bis(trimethylsilyloxy)naphthalene 5b was prepared from naphthalene-2,7-diol following the general procedure for the preparation of bis-silyl “BB” monomers, with substitution of tert-butyldimethylsilyl chloride with trimethylsilyl chloride. 5b was isolated as a yellow oil (13.1 g, 43.5 mmol, 99%): IR (neat) λmax 2958, 2856, 1630, 1604, 1507, 1460, 1427, 1365, 1250, 1211, 1151, 1110, 909, 833, 743, 697, 612, 489 cm−1; 1H NMR (400 MHz, CDCl3) δ 7.69 (d, J=8.9 Hz, 2H), 7.12 (d, J=2.3 Hz, 2H), 6.99 (dd, J=2.3, 8.8 Hz, 2H), 0.37 (s, 18H); 13C NMR (100 MHz, CDCl3) δ 153.6, 136.2, 129.3, 125.4, 120.0, 114.0, −0.42; LRMS (EI) m/z=304.1 [M]+.
