Fluorine-containing aromatic compound and method for producing same

摘要

Disclosed is a fluorine-containing aromatic compound represented by the following general formula (1) and its production method. In the formula (1), R1 is a hydroxyl group or amino group, each of R2 to R5 is independently a hydrogen atom, or a C1-4 straight chain or a C3 or C4 branched chain alkyl group, hydrogen atoms of the alkyl group may partially or totally be replaced with fluorine atoms, n is an integer of 0 to 2, and each of m and l is independently 0 or 1. A polymer derived from this fluorine-containing aromatic compound contains —C(CF3)2OH group at a position away from the polymer main chain. Therefore, it is useful for resist use.;
