Abstract :
A combination of N-arylstilbazolium organic nonlinear optical chromophores with iodoargentates results in five new hybrids, i.e.,[(DAST)(Ag2I3)](n), (1), [(DMAQS)(Ag2I3) (2), [(DPAS)(Ag2I3)]n( )(3), [(DPTAS)(2)(Ag5I7)](n) (4), and [(CEMAS)(2)-(Ag5I7)](n) (5). Among them, the former four are centrosymmetric, and 5 is non-centrosymmetrical (space group Pna2(1)) with the introduction of a cyano group in an organic chromophore. The (Ag5I7)(n)(2n-) chains in 4 and 5 are special, in which that of 4 is constructed from Ag5I10 building blocks with a mu(6)-I sigma-bonding to six Ag ions, and that in 5 is the connection of a cubane-like Ag4I4 core with bridged AgI4 tetrahedra. UV/vis/near-IR adsorptions and near-IR photoluminescences have been observed. All the organic chromophores are stacked as head-to-tail arrangements, resulting in second harmonic generation (SHG) inactive in 1-4. But 5 is SHG active without J-aggregation of organic chromophore, whose symmetry break was driven by the formation of hydrogen bonds around the cyano group. The SHG activity of 5 originates from the polarizations of the asymmetric contribution of Ag5I94- unit mixing with non-centrosymmetrical (CEMAS)(2)(2+ )pair. Theoretical calculations were carried out to disclose their electronic structures.

Abstract :
目的:比较用手术方法或保守疗法(增肥、药物)治疗咽鼓管异常开放症的疗效。方法手术治疗:腭帆张肌松弛术必要时咽鼓管鼓口半堵管术;增肥或药物的保守治疗。结果22例中行单、双侧腭帆张肌松弛术,其中有7例加行咽鼓管鼓口半堵管术,全部愈好或基本愈好。保守治疗10例中6例愈好,4例未愈。结论手术治疗值得推荐。
