摘要

Two tritylthio-based compounds were synthesized: 1-bromo-3-tritylthiopropane 1 and 2-(tritylthio)-ethanethiol 2. They were characterized by infrared, NMR, UV-Vis absorption and fluorescence spectroscopy and single-crystal X-ray diffraction. The crystals of both compounds crystallize in the monoclinic space group P2(1)/c. The unit cell dimensions of 1 are a = 7.4072 (9) angstrom, b = 9.6924 (11) angstrom, c = 25.652(3) angstrom, beta = 90.023 (2)(o), and V = 1841.7 (4) angstrom(3), and of 2 are a = 15.3532 (8) angstrom, b = 14.1552 (7), c = 7.8249 (4) angstrom , beta = 94.5239 (8)(o), and V = 1695.27 (15) angstrom(3). The packing structures of 1 and 2 are supported by weak pi-pi and hydrogen bond interactions. Both 1 and 2 have absorption maxima at 257 nm, and emission maxima at 314 nm and 313 nm, respectively. The compounds differ by the presence of the S-H stretching vibration at similar to 2550 cm(- 1) in 2 and its absence in 1, as observed in the infrared spectra.
