Abstract
The present invention relates to pyrrole derivatives and photosensitive film using the same and more particularly, the pyrrole derivatives consist of pyrrole units to allow polymerization chemically and electrochemically and a perylene diimide unit to absorb light so that perylene diimide film can be produced by crosslinking the pyrrole units by irradiation of visible light having wavelengths longer than 500 nm and become insoluble in most solvents. Such perylene diimide films can be widely used in the manufacture of electrical, electronical and optical devices such as photo diodes, solar batteries, liquid crystal displays, and luminescent diodes, etc.
