This invention relates to a photocleavable mass tag and the use thereof, and particularly to a thiochromene-type compound useful for MALDI-TOF (Matrix-Assisted Laser Desorption/Ionization Time-Of-Flight) mass spectrometry or matrix-less LDI-TOF (Laser Desorption/Ionization Time-Of-Flight) mass spectrometry and the use thereof.

Thiochromene type compound and use thereof

A block copolymer is provided. The block copolymer according to an exemplary embodiment includes a first block represented by Chemical Formula 1 and a second block represented by Chemical Formula 2: wherein COM1 and COM2 are independently selected from a polystyrene moiety, polymethylmethacrylate moiety, polyethylene oxide moiety, polyvinylpyridine moiety, polydimethylsiloxane moiety, polyferrocenyldimethylsilane moiety, and polyisoprene moiety, R1 is hydrogen or an alkyl group with 1 to 10 carbon atoms, Ph is a phenyl group, a is 1 to 50, R2 is hydrogen or an alkyl group with 1 to 10 carbon atoms, and b is 1 to 50.

Block copolymer, method of forming the same, and method of forming pattern

A block copolymer includes: a first block, and a second block copolymerized with the first block. The second block includes a silyl group including a ring-type functional group.

Block copolymer and pattern forming method using the same

A method of forming patterns includes forming a layer composed of a ketene based random copolymer on a substrate, forming a block copolymer on the ketene based random copolymer layer and patterning the ketene based random copolymer layer by removing a part of the block copolymer and a portion of the ketene based random copolymer layer.

Block copolymer and method of forming patterns by using the same

Random copolymer for forming neutral surface and methods of manufacturing and using the same

Disclosed is a compound represented by the following Formula 1: The compound exhibits improved solubility and thermal stability in an organic light emitting device. An organic light emitting device including the compound, improves the driving voltage, the emission efficiency, and the color purity of an organic light emitting display.

Organic compound and organic light emitting device containing the same

The present invention relates to a free radical initiator and a method for peptide sequencing using the same. Compared with diazo or peroxy functionalized precursors, the precursors using the present compounds are chemically more robust and can generate radical species by homolytic cleavage upon thermal activation, enabling sequencing of a wider variety of peptides. In addition, the present invention makes it feasible to sequence peptides carrying disulfide bonds.
