Optical materials with improved heat resistance, especially dopant-type GI POFs with improved heat resistance are provided. These optical materials each comprises at least one aromatic sulfide compound represented by the following formula (1):
wherein
n stands for an integer of from 2 to 12,
k stands for an integer of from 1 to n,
A represents a substituted or unsubstituted, n-valent carbocyclic aromatic ring or heterocyclic aromatic ring, and
B1 to Bn each independently represent a substituted or unsubstituted, carbocyclic aromatic group or heterocyclic aromatic group.
本研究提供了耐热性更好的光学材料,特别是耐热性更好的掺杂型 GI POF。这些光学材料各自包含至少一种由下式(1)表示的芳香族硫化物化合物:
其中
n 代表 2 到 12 之间的整数、
k 代表 1 至 n 的整数、
A 代表取代或未取代的 n 价碳环芳香环或杂环芳香环,以及
B1 至 Bn 各自独立地代表取代或未取代的碳环芳香基团或杂环芳香基团。
