A method for synthesizing halogenated organic compounds, such as halogenated alkenyl group-containing and halogenated alkyl group-containing compounds having a heteroatom (e.g., O,N.S) coupled to a carbon atom of a halogenated alkenyl or halogenated alkyl group, involves reacting a halogenated olefin such as a chloro-substituted trifluoropropenyl compound with an active hydrogen-containing organic compound such as an alcohol (e.g., an aliphatic monoalcohol, aliphatic polyalcohol, or a phenolic compound), a primary amine, a secondary amine or a thiol.

An ionic compound capable of providing a cured material having superior antibacterial property and oxygen permeability, and a composition containing the ionic compound, and a cured material, a hydro gel and an ophthalmic lens which have long-term sustainable antibacterial property and superior oxygen permeability. The ionic compound is represented by the following formula (1):
In formula (1), P represents a polymerizable functional group. Q
+
represents a cationic group: Z represents an n-valent siloxanyl group in which the total atomic weight of a group of constituent atoms is no less than 70 and no greater than 1,000; X
m−
represents an m-valent anion; and n is an integer of 1 to 10, where provided that n is no less than 2, a plurality of P3 and Q
+
3 are each independently as defined above.
The present invention concerns functionalized photoreactive compounds of formula (I), that are particularly useful in materials for the alignment of liquid crystals. Due to the adjunction of an electron withdrawing group to specific molecular systems bearing an unsaturation directly attached to two unsaturated ring systems, exceptionally high photosensitivities, excellent alignment properties as well as good mechanical robustness could be achieved in materials comprising said functionalized photoreactive compounds of the invention.
