The present invention relates to novel compounds, particularly to compounds comprising a photoactive unit, said novel compounds being particularly suitable for compositions and ophthalmic devices as well as to compositions and ophthalmic devices comprising such compounds.
Film-forming materials include nonionic metal coordinating structures. Nonionic metal coordinating structures can coordinate metals, such as metal catalysts and metal substrates. Example film-forming materials can be the product of a poly-functional epoxide and a nucleophilic ligand having a nonionic metal coordinating structure, or the product of a poly-functional alcohol and an electrophilic ligand having a nonionic metal coordinating structure.
