Abstract
The present application can provide a phthalonitrile compound and a use thereof. The phthalonitrile compound has a novel structure, and can exhibit an excellent effect in a use to which the phthalonitrile compound can be applied. An example of the use of the phthalonitrile compound may be a raw material or precursor for, so-called, a phthalonitrile resin, a phthalocyanine dye, a fluorescent whitening agent, a photographic sensitizer, an acid anhydride, or the like.
Claims11
A phthalonitrile resin comprising polymerized units derived from a compound represented by Formula 1 below:
- wherein, P1 and P2 are the same or different aryl groups from each other, A1 and A2 are the same or different arylene groups from each other, L1 to L3 are each independently an alkylene group, an alkylidene group, an alkenylene group or an alkynylene group, and P1, P2, A1 and A2 are each substituted with at least one substituent represented by Formula 2 below,
- wherein, L4 is an alkylene group, an alkylidene group, an oxygen atom or a sulfur atom, and R1 to R5 are each independently hydrogen, an alkyl group, an alkoxy group, an aryl group or a cyano group, provided that at least two of R1 to R5 are a cyano group.
