The invention provides fluorinated derivatives of methoxydibenzo[b,f]oxepin of general formula (1) and general formula (2) and a method for obtaining thereof in a catalysed reaction of fluoroazobenzene with methoxydibenzo[b,f]oxepin. The preferable catalyst of the reaction is triethylamine, and the compounds obtained may be useful as molecular switches in biological systems and photopharmacology.

The present disclosure provides thionolactones (e.g., compounds of Formula II, and tautomers and salts thereof). The thionolactones may be useful as comonomers to copolymerize with other comonomers, e.g., methacrylates (e.g., MMA) to generate copolymers, e.g., random copolymers. The copolymers may be degradable (e.g., backbone degradable). The copolymers may be useful for waste management or biodegradability.
