In particular, the chalcogenide hybrid organic/inorganic polymers of the invention comprise a hydrocarbon cyclic ring structure and one or more chalcogenide selected from the group consisting of sulfur, selenium, cyclic selenium sulfide, and a combination thereof.

Disclosed is an optically softening resin composition, containing: a compound having a disulfide bond; and a radical scavenger. Further disclosed is a curable resin composition, containing: a monomer having a disulfide bond and a functional group; a monomer having a substituent reactive with the functional group; and a radical scavenger.

The method of producing an optical material of the present disclosure includes a step of mixing a resin monomer for an optical material and an additive to prepare a polymerizable composition for an optical material having a hue specified by L* of 70 or more b* of from −30 to 10 in the CIE 1976 (L*, a*, b*) color space when measured at a thickness of 10 mm, and a step of polymerizing and curing the polymerizable composition for an optical material.

The present disclosure provides a polymer, a quantum dots film layer and a preparation method thereof. The polymer includes a plurality of polymerized units, and each of the polymerized units includes a hydrophobic structure and a carrier transport structure. The hydrophobic structure is linked to the carrier transport structure via a bridge bond containing a functional atom, and the hydrophobic structure is provided with a first ligand. When the polymerized unit is broken at the bridge bond, a hydrophobic monomer containing the first ligand and a carrier transport monomer containing a second ligand are generated. The second ligand includes the functional atom, and the second ligand is stronger than the first ligand in coordination activity.
