Abstract:
Provided is a mercapto-based polysilsesquioxane having a thiol group (—SH) introduced to at least one side chain of polysilsesquioxane, represented by the following Chemical Formula 1 (In Chemical Formula 1, each of R1, R2 and R3 is independently selected from the group consisting of a thiol aromatic group, thiol aliphatic group and organic functional group, wherein at least one of R1, R2 and R3 is a thiol aromatic group or thiol aliphatic group, and n is an integer of 1-10,000).
