There is provided a polygermane compound forming a film having a high refractive index and thermal stability, and containing a sulfur atom-containing organic group as a group bonded to a germanium atom. A polygermane compound comprising a sulfur atom-containing organic group as a group bonded to a germanium atom, in which the sulfur atom-containing organic group is a group of Formula [1]: -L-Z [1] where L is a single bond, a C1-6 alkylene group, or a C4-20 arylene group optionally substituted with a C1-6 alkyl group; and Z is a C1-20 sulfide group, a C1-14 cyclic sulfide group optionally substituted with a C1-6 alkyl group, a C2-20 alkyl group containing a sulfide bond, or a C5-20 aralkyl group containing a sulfide bond, with a proviso that when L is a single bond, Z is not a C1-20 sulfide group.

There is provided a high refractive-index coating film and a production method of the high refractive-index coating film. The production method comprises producing a coating film containing a germanium compound containing a Ge—Ge bond as a backbone thereof, and baking the coating film under vacuum or in an inert gas atmosphere. The high refractive-index coating film produced by the method is soluble in a solvent and has a high moldability and film-formation property, and has a high refractive index of 1.8 or more and further 2.3 or more, and is chemically stable.

A fluorine-containing polymer obtained using a 1,6-diene ether compound represented by formula [1] is a high-performance polymer exhibiting a low refractive index, high glass transition point, a high degree of transparency, and solubility in solvents. There are many potential uses, such as use as a coating material or bulk material. For example, said polymer could be effectively used in high-tech fields such as: optical materials such as low-reflection films and optical waveguide cladding; semiconductor materials such as pellicles and resists in semiconductor lithography; and protective film materials, insulating film materials, and water-repellent materials. (In the formula, R1 represents a C6-18 aryl group or a C1-12 alkyl group, which may be substituted.)

Disclosed is a fluorine-containing polymer obtained by polymerizing a 1,6-diene-type ether compound represented by formula [1] and, for example, a (meth)acrylic acid compound represented by formula [2]. The fluorine-containing polymer shows high transparency, has a high glass transition point, and is soluble in a solvent and therefore has moldability. In the case where a (meth)acrylic unit has a reactive substituent, by utilizing the crosslinking reaction thereof, a thin film having high solvent resistance can be produced. In formulae [1] and [2], R1 and R2 each independently represent a hydrogen atom or an alkyl group having 1 to 12 carbon atoms, which may be substituted, R3 represents a hydrogen atom, a fluorine atom, or a methyl group, and R4 represents a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, which may be substituted, or an aromatic group having 5 to 10 ring members, which may be substituted.
