    • A smoking article having reduced ignition propensity is disclosed. The smoking article (10) includes a tobacco column (12), a wrapper (14) surrounding the tobacco column and a filter element (16). The wrapper has a base permeability, and untreated areas (20) alternating with discrete areas (22) treated with a composition to reducing the base permeability. The discretely treated areas (22) interact with a coal of a burning tobacco firecone as it advances to self-extinguish the smoking article. The composition of the treated areas includes a permeability reducing substance, a burn rate retarding substance and a burn rate accelerating substance. Either the burn rate retarding substance or the burn rate accelerating substance acts as an organoleptic enhancing substance. In this way a smoker's experience when smoking either the treated areas or the untreated areas is substantially the same.
    • 公开了具有降低的点火倾向的吸烟制品。 吸烟制品(10)包括烟草柱(12),围绕烟草柱的包装(14)和过滤元件(16)。 包装物具有基础渗透性,并且未处理区域(20)与用组合物处理以降低基础渗透性的离散区域(22)交替。 离散处理区域(22)与燃烧的烟草火鸡的煤相互作用,因为它前进以自动熄灭吸烟物品。 处理区域的组成包括渗透率降低物质,燃烧速率阻滞物质和燃烧速度加速物质。 燃烧速率缓慢物质或燃烧速率加速物质都可以用作感官增强物质。 以这种方式,吸烟者在经过治疗的地区或未经治疗的地区吸烟时的经验基本相同。

    • Our results thus identify two sets of necessary and sufficient criteria for observing long-wavelength emission from acridinium compounds: Set A: (a) the creation of an extended conjugation system by the attachment of appropriate functional groups on the acridinium nucleus (electronic requirement). (b) Coplanarity of the attached functional group and the acridone moiety during light emission (geometry requirement). (c) Said functional group must consist of at least one aromatic ring and one electron-donating atom or group with an extra pair of electrons which can readily delocalize into the extended π system to which the heteroatom is directly attached or built into, and establish stable extended resonance with the electron-withdrawing carbonyl moiety of the light emitting acridone. Such electron-donating atom or group that exists in the form of an anion has particularly strong effect to further the bathochromic shift of the emission wavelength. Set B: (a) A direct attachment at one or more of positions C-2, C-4, C-5, or C-7 of the acridinium nucleus, of electron-donating atoms or groups having extra pair(s) of electrons. The electron-donating entities can be the same or different if more than one electron-donating entity is used. Such electron-donating atom or group that exists in the form of an anion has particularly strong effect to further the bathochromic shift of the emission wavelenth. For molecules for which the above criteria are met such as LEAE, 3-HS-DMAE, and 2-hydroxy-DMAE long wavelength-emission exceeding 500 nm and reaching into NIR region is expected and observed. Preferably, the utility of an NIR-AC of comparable quantum yield as the conventional acridinium compounds goes hand-in-hand with the employment of a luminescence detector of good to excellent detection efficiency. To achieve efficient NIR signal detection and facilitate the performing of diagnostic assays, a further objective of the present invention is the advance of a concept and the realization of substituting a state-of-the-art charge-coupled device (CCD) detector for the red-insensitive photomultiplier tube (PMT) in a conventional fully or semi-automatic analyzer such as MLA-II of Chiron Diagnostics, Walpole, MA.
