高耐熱性含硫黄有機置換ポリゲルマン化合物
Document Type and Number:
Japanese Patent JP5762391
Kind Code:
B2
Abstract:
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]:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ-L-Z€ƒ€ƒ€ƒ€ƒ€ƒ[1]
where L is a single bond, a C 1-6 alkylene group, or a C 4-20 arylene group optionally substituted with a C 1-6 alkyl group; and Z is a C 1-20 sulfide group, a C 1-14 cyclic sulfide group optionally substituted with a C 1-6 alkyl group, a C 2-20 alkyl group containing a sulfide bond, or a C 5-20 aralkyl group containing a sulfide bond, with a proviso that when L is a single bond, Z is not a C 1-20 sulfide group.
