Described herein are embodiments of squarylium compounds for use as filters in light-emitting and/or display devices. One problem of known quarylium dyes is that strong nucleophiles can attack the electron-deficient cyclobutene ring which can lead to a loss of the dye's colour. Another potential drawback with squaraine dyes can be their tendency to form aggregates, which can lead to a substantial broadening of their absorption bands. Use of the present compounds in filters address these problems. The squarylium compounds of the present invention have the following formulas:

Provided is a circularly polarizing plate that is excellent in antireflection characteristic, and that can be produced at low cost. The circularly polarizing plate of the present invention includes in the stated order: a polarizer; a retardation layer (20a) configured to function as a /4 plate; and a colored layer, wherein an angle formed by an absorption axis of the polarizer and a slow axis of the retardation layer (20a) is from 35 to 55, wherein the colored layer has an absorption peak in a wavelength band in a range of from 580 nm to 610 nm, and wherein the colored layer contains a compound X represented by the general formula (I) or the general formula (II).

Provided is an optical laminate having the following feature: when the optical laminate is used in an image display apparatus, the optical laminate can express a sufficient brightness, can express a satisfactory hue, and can achieve a cost reduction while suppressing a reflectance. The optical laminate of the present invention includes: a wavelength conversion layer; and an absorption layer arranged on one side of the wavelength conversion layer, wherein the absorption layer has an absorption peak in a wavelength band in a range of from 580 nm to 610 nm, and wherein the absorption layer contains a compound x represented by the general formula (I) or the general formula (II).

A process for providing phycocyanin from a blue-green algae biomass comprising the steps of forming a slurry of blue-green algae by mechanically mixing the blue-green algae in water to break up filaments of the biomass and incubating the macerated slurry in a container with at least a 1% flocculating agent for a period of time sufficient to separate a blue extract from the slurry. The blue extract is separated and filtered through a filter to obtain a blue filtrate and the blue filtrate is mixed in a container with an ammonium sulfate precipitate for a suitable period of time to obtain supernatant protein separation. The supernatant is syphoned from the container and the settled participate is centrifuged at a rpm ranging from about 3500 rpm to about 4500 rpm for a sufficient time to produce phycocyanin precipitate. The phycocyanin precipitate is spray dried to form a phycocyanin powder which is collected and purified with a citrate and water mixture to obtain a supernatant and phycocyanin residue with the phycocyanin residue being redissolved in water and sprayed to dry into a phycocyanin powder.

Provided are methods for making and using chiral, non-racemic protected organoboronic acids, including pinene-derived iminodiacetic acid (PIDA) boronates, to direct and enable stereoselective synthesis of organic molecules. Also provided are methods for purifying PIDA boronates from solution. Also provided are methods for deprotection of boronic acids from their PIDA ligands. The purification and deprotection methods may be used in conjunction with methods for coupling or otherwise reacting boronic acids. Iterative cycles of deprotection, coupling, and purification can be performed to synthesize chiral, non-racemic compounds. The methods are suitable for use in an automated chemical synthesis process. Also provided is an automated small molecule synthesizer apparatus for performing automated stereoselective synthesis of chiral, non-racemic small molecules using iterative cycles of deprotection, coupling, and purification.
