Unsymmetrical cyanine dimer compounds and their application

Embodiments of the present invention provide methods and nucleic acid reporter molecules for the detection of nucleic acid in a sample. The nucleic acid reporter molecule comprises two unsymmetrical cyanine monomer moieties, which may be the same or different, that are covalently attached by a linker comprising at least one aromatic, heteroaromatic, cyclic or heterocyclic moiety comprising 3-20 non-hydrogen atoms selected from the group consisting of O, N, S, P and C. The linker may be rigid, relatively flexible or some degree thereof. The unsymmetrical cyanine monomer moieties comprise a substituted or unsubstituted benzazolium moiety and a substituted or unsubstituted pyridinium or quinolinium moiety that is connected by a methine bridge that is monomethine, trimethine or pentamethine. The linkers form the cyanine dimer compounds by attaching to the pyridinium or quinolinium moiety of the monomer moieties. The present nucleic acid reporter molecules find utility in forming a nucleic acid-reporter molecule complex and detecting the nucleic acid.

An oxime ester compound of specified structure. In particular, in a photopolymerizable composition comprising (a) black color material, (b) organic binder and (c) photopolymerization initiator, the oxime ester compound constitutes the component (c). The oxime ester compound can be used as a highly sensitive photopolymerization initiator. The photopolymerizable composition containing the oxime ester compound in the form of a thin film excels in sensitivity and resolving power while exhibiting high light shielding capability, so that it is capable of forming a resin black matrix (BM) of low cost but high quality. The color filter utilizing this resin BM excels in precision, flatness and durability, so that it is capable of enhancing the display quality of liquid crystal device. Moreover, the production process and color filter per se do not involve any hazardous substances, so that the danger to human body can be reduced and environmental safety can be enhanced. Application thereof can be made to usages in which no color material is used, such as photospacer and rib (liquid crystal divided-alignment protrusion).

Acylhydrazone zinc protoporphyrin, and synthesis and application of complex thereof

The invention discloses an acylhydrazone zinc protoporphyrin and a zinc and cobalt complex thereof, belonging to the field of chemical synthesis. In the acylhydrazone zinc protoporphyrin, an acylhydrazone structure and a porphyrin structure form a large conjugated system which can absorb a wider range of sunlight as compared with most of porphyrin dyes; and in the zinc and cobalt complex of the acylhydrazone zinc protoporphyrin, acylhydrazone zinc protoporphyrin molecules are connected to form a chain structure or high-dimensional structure, thereby improving the electron transfer efficiency and consequently improving the photoelectric conversion efficiency. Thus, the zinc and cobalt complex can be used as a dye sensitizer for the preparation of fuel-sensitive solar cells. Photoelectric property test results show that the fuel-sensitive solar cells prepared by the invention are capable of outputting a certain current to an external load and have different degrees of photoelectric conversion efficiency under the irradiation of standard light; and for the photocell using the zinc complex of the zinc protoporphyrin acylhydrazone as the dye, the maximum IPCE (Incident Photon to Current Efficiency) value is 13.4%.
