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%.

The invention provides a conjugated Schiff base Zn (zinc) porphyrin compound, and belongs to the technical field of chemical synthesis. In the preparation method, porphyrin compound is made from nitrobenzaldehyde and pyrrole by four reaction steps of condensation, reduction, coordination and substitution. Because of a large conjugated system of Schiff base and porphyrin, the sunlight absorptivity of the porphyrin compound is improved, the maximum IPCE (incident photon-to-electron conversion efficiency) value can reach 25%, and the photoelectric conversion efficiency Eta also reaches 0.40, thus the conjugated Schiff base Zn porphyrin compound has good application prospect in preparation of a dye sensitized solar cell. Compared with the traditional ruthenium dye, the obtained conjugated Schiff base Zn porphyrin compound has the advantages that raw materials are cheap and obtained easily, synthetic process is simple, reaction condition is mild, no expensive metal raw material is used, and the effects of low cost, high yield and less environmental pollution are achieved.
