Abstract
Disclosed is a fluorine-containing aromatic compound represented by the following general formula (1) and its production method. In the formula (1), Ris a hydroxyl group or amino group, each of Rto Ris independently a hydrogen atom, or a Cstraight chain or a Cor Cbranched 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(CF)OH group at a position away from the polymer main chain. Therefore, it is useful for resist use.
