The invention provides compounds of Formula (I), or pharmaceutically acceptable salts thereof: ##STR00001##
The compounds, compositions, methods and kits of the invention are useful for the treatment of pain, cough, itch, and neurogenic inflammation.

Provided are a fluorinated compound for patterning a metal or an electrode (cathode), an organic electronic element using the same, and an electronic device thereof, wherein a fine pattern of the electrode is formed by using the fluorinated compound as a material for patterning a metal or an electrode (cathode), without using a shadow mask, and it is possible to more easily apply UDC since it is easy to manufacture a transparent display having high light transmittance.
