  摘要：

  一系列相对分子量较高（550-810）的四(4-羟基苯基)戊烷和四(4-羟基苯基)-对二甲苯被制备并通过氧吸收法在60°C下作为四氢萘的抗氧化剂进行评估。在酚羟基的邻位引入烷基基团被证明可以提高这两个系列化合物的抗氧化活性。

  A photoactive compound is used in combination with a photosensitizer, represented by the following formula (1): A −[( J ) m −( X-Pro )] n (1) wherein A represents a hydrophobic unit comprising at least one kind of hydrophobic groups selected from a hydrocarbon group and a heterocyclic group, J represents a connecting group, X-Pro represents a hydrophilic group protected by a protective group Pro which is removable by light exposure, m represents 0 or 1, and n represents an integer of not less than 1. The protective group Pro may be removable by light exposure in association with the photosensitizer (especially, a photo acid generator), or may be a hydrophobic protective group. The hydrophilic group may be a hydroxyl group or a carboxyl group. The photoactive compound has high sensitivity to a light source of short wavelength beams, for resist application, therefore, the photoactive compound is advantageously used for forming a pattern with high resolution.
