  According to the present invention, a polymer is obtained by polycondensation of a fluorinated dicarboxylic acid derivative of the general formula (M-1) or an acid anhydride of the fluorinated dicarboxylic acid with a polyfunctional compound having two to four reactive groups corresponding in reactivity to carbonyl moieties of the fluorinated dicarboxylic acid derivative or acid anhydride. [Chem. 134] AOCF 2 C-Q-CF 2 COA′  (M-1) In the above formula, Q represents a divalent organic group having a substituted or unsubstituted aromatic ring; and A and A′ each independently represent an organic group. This polymer exhibits a sufficiently low dielectric constant for use as a semiconductor protection film and has the capability of forming a film at a relatively low temperature of 250° C. or lower.

  根据本发明，通过将通式(M-1)的含氟二羧酸衍生物或含氟二羧酸酸酐与具有与含氟二羧酸衍生物或酸酐的羰基部分相对应的两到四个反应性基团的多官能化合物进行聚合缩合反应，可以得到一种聚合物。[Chem. 134]AOCF2C-Q-CF2COA′  (M-1)在上述公式中，Q代表具有取代或未取代芳香环的二价有机基团; A和A'各自独立地表示有机基团。该聚合物表现出足够低的介电常数，可用作半导体保护膜，并具有在相对较低的温度下（250℃或更低）形成膜的能力。

  The present invention provides compositions, apparatuses and methods for detecting one or more nucleic acid targets present in a sample. Methods of the invention include utilizing two or more oligonucleotide probes that reversibly bind a target nucleic acid in close proximity to each other and possess complementary reactive ligation moieties. When such probes have bound to the target in the proper orientation, they are able to undergo a spontaneous chemical ligation reaction that yields a ligated oligonucleotide product. In accordance with the invention, the presence of the target(s) of interest can be determined by measuring the presence or amount of ligated oligonucleotide product.
