The present invention relates to a dendritic photoactive compound that comprises oxime ester and a method for producing the same. Since the compound according to the present invention comprises two or more oxime ester groups and chromophores in one molecule at the same time, the solubility in respects to the organic solvent and the efficiency for producing a radical by absorbing ultraviolet rays are excellent. In addition, it can act as an effective initiator in respects to the photopolymerization of the unsaturated group, in particular, the acryl compound.

A novel photoactive compound is provided. The photoactive compound has a structure represented by Formula 1: wherein R1, R2, R3, A, X, Y, n and m are as defined in the specification. The photoactive compound efficiently absorbs UV light. Accordingly, the photoactive compound has an improved ability to generate radicals and is efficiently photopolymerized with unsaturated bonds. Further provided is a photosensitive resin composition comprising the photoactive compound. The photosensitive resin composition has good sensitivity because it efficiently absorbs UV light. In addition, the photosensitive resin composition has excellent characteristics in terms of residual film ratio, mechanical strength and resistance to heat, chemicals and development. Therefore, the photosensitive resin composition is advantageously used in curing materials for column spacers, overcoats and passivation films of liquid crystal display devices. In addition, the photosensitive resin composition has excellent thermal processing characteristics.

A method for manufacturing an array plate for biomolecules includes coating a surface of a substrate with a hydrophobic material to form a hydrophobic layer having initial hydrophobic properties, etching the hydrophobic layer through an etch mask placed thereon to form a hydrophilic binding site, removing the etch mask, and processing the remaining region of the hydrophobic layer to recover the initial hydrophobic properties. A method for manufacturing a biochip using this array plate, includes processing the surface of the hydrophilic binding site of the array plate to increase an affinity of biomolecules to the hydrophilic binding site, and applying a solution containing biomolecules to the surface of the hydrophilic binding site.

A photopolymerization initiator is provided. The photopolymerization initiator contains at least one unsaturated double bond and at least one oxime ester group in the molecule. The photopolymerization initiator comprises a compound represented by Formula 1 or 2: wherein R1 and R2 are each independently —CH3, —C2H5, —C3H7 or —C6H5; wherein R3, R4 and R5 are each independently —CH3, —C2H5, —C3H7 or —C6H5. Further provided is a photosensitive resin composition comprising the photopolymerization initiator. The use of the photosensitive resin composition in photolithography reduces the formation of volatile residue during post-development baking.

摘要:
A control rod driving simulator has a control rod driving unit having a plurality of coil members vertically mounted therein, a control rod mounted vertically movably through the centers of the coil members, a cart having a reserve tank storing cooling water, a cooling fan for air-cooling the coil members and a control unit for controlling an operation of the cooling fan, a box containing a part of the control rod and a checking unit for checking the vertical movement of the control rod. When the simulator is connected to an actual control rod driving mechanism and a wave profile of current flowing in the coil members of the control rod driving unit is measured, a same wave profile of current as when it is connected to an actual control rod driving mechanism provided to a reactor core can be obtained.
