The title compound （C29H33NO2, 3） was synthesized and structurally characterized by elemental analysis, IR, MS, 1H- and 13C-NMR and single-crystal X-ray diffraction. The crystal is of monoclinic system, space group P21 with a = 14.428（3）, b = 7.3440（15）, c = 22.768（5） A, β = 95.17（3）°, V = 2402.7（8） A3, Z = 4, Mr = 427.56, Dc = 1.182 g/cm3, F （000） = 920, 2（MoKa） = 0.71073 A,μ = 0.073 mm-1, the final R= 0.0670 and wR= 0.1002 for 2437 reflections with I〉 2σ（I） Two crystallographically independent molecules with different conformations co-exist in the structure. The crystal structure is stabilized by intermolecular C-H…π interactions which make the molecules stack along the b axis. In addition, the preliminary cytotoxic assay showed that the title compound exhibited moderate inhibitory activity against KB and SW1116 cells.

The chemical composition of unpleasant smell, emitted from the production process of wood-plastic composites using Manchurian ash sawdust （Fraxinus mandschurica Rupr.） and polypropylene powder as the raw material, was investigated. Wood sawdust and polypropylene powder were subjected to heat treatment to 290℃ during 8 min （the conditions were similar to those employed on an industrial scale）. The emitted compounds were collected and analyzed by gas chromatography-mass spectrometry （GC-MS）. The analytical results showed that the unpleasant smell was emitted from the pyrogenation of wood sawdust rather than from the polypropylene powder. Nine types of compounds （hydrocarbons, ethers, phenols, aldehydes, ketones, alcohols, acids and their derivatives, furan and its derivatives, and nitrogen-containing compounds） were collected in the gas phase during heating. Among those 126 components detected by GC-MS, 112 compounds were identified.

We study the near-field response of a shell nanocylinder pair, with its core filled by gain materials, using a two- dimensional finite-difference time-domain method. It is shown that the gain materials in the core of the cylinder can compensate for the intrinsic absorption of the metal shell, leading to local-field enhancement in the gap of the active pair. A linear dependence is found between the field enhancement and the gain coefficient at resonance. The detailed physics is studied by calculating the electrical-field distribution of the shell pair filled with different gain materials. The influence of the gap width and the shell thickness on the interaction of two adjacent active shell cylinders is also investigated.
