    Abstract: A reactive porogen based on organic noncyclic-polyol, and ultra-low dielectric materials prepared by using the same porogen are provided not to remain carbon residue after semiconductor-manufacturing process, and produce ultra-low dielectric materials having enhanced mechanical properties based on the same porosity and small size of pores, so that the ultra-low dielectric materials are useful as interlayer insulating film of next generation semiconductor for copper wiring. The reactive porogen is prepared by replacing the terminal hydroxy group of organic noncyclic-polyol by alkylalkoxysilane, wherein the organic noncyclic-polyol is completely pyrolyzed at 350-500 deg.C not to remain carbon residue; and the organic noncyclic-polyol is erythritol represented by the formula(1): (HOH2C)3C-CH2-OR or petaerythritol organic compound represented by the formula(2): HOCH2[CH(OH)]nCH2OH, wherein R is H, CH2C(CH2OH)3 or CH2C(CH2OH)2CH2OCH2C(CH2OH3), and n is an integer from 2 to 4. The ultra-low dielectric material composition comprises 10-90 volume% of organic or inorganic silicate precursor as an organic silicate matrix and 10-90 volume% of the porogen as a porogenic template, wherein the matrix is polymethylsilsesquioxane monopolymer or copolymer. The ultra-low dielectric materials are prepared by preparing a thin layer with the ultra-low dielectric material composition, and sol-gel reacting and heat-treating the thin layer.

    Abstract: 본발명은펩타이드서열동정을위한신규한자유라디칼개시제및 이를이용한펩타이드서열의동정방법에관한것이다. 본발명의자유라디칼개시제는벤젠고리내 브롬이치환됨으로써이온화과정에서생성되는이온절편들중-말단절편으로부터-말단절편을보다용이하게구분할수 있도록한다. 본발명은절편화스펙트럼의해석에서의변수및 복잡성을크게낮추어, 다른분광학적데이터없이질량분광분석결과만으로도복잡한구조의분석대상펩타이드의시퀀싱을매우용이하게수행할수 있도록한다.

    Abstract translation: 本发明涉及用于鉴定肽序列的新型自由基引发剂，以及使用其的肽序列鉴定方法。 本发明的自由基引发剂通过在苯环中取代溴来确保在离子化过程中产生的离子片段中C末端片段更容易鉴定N-末端片段。 此外，本发明显着降低了对分裂谱的分析的可变性和复杂性，从而使得可以容易地对具有复杂结构的测试肽进行重新测序，仅使用质谱的结果，而不需要其它光谱 数据。
