从某类磺酸盐衍生的酸放大器在强酸存在下进行自催化分解，得到相应的磺酸，催化母体磺酸盐的分解，导致以指数方式释放更多相同的磺酸。介绍了五种显示酸增殖反应的酸放大器。特定类型的氨基甲酸酯表现出自催化断裂，与二氧化碳一起产生相应的脂肪胺和烯烃，而生成的胺能够作为断裂的催化剂，因此氨基甲酸酯被称为碱放大器。酸和碱放大器在光功能材料（包括光刻胶）中的应用，描述为分子放大器与光酸以及光碱发生器相结合的结果。讨论了酸扩散反应在聚合物薄膜中的实际应用。
Acid amplifiers derived from a certain class of sulfonates suffer from autocatalytic decomposition in the presence of a strong acid to give corresponding sulfonic acids, which catalyze the decomposition of the parent sulfonates, leading to the liberation of more of the same sulfonic acids in an exponential manner. Five types of acid amplifiers displaying acid proliferation reactions are presented. A certain type of carbamate exhibits autocatalytic fragmentation to give the corresponding aliphatic amine and olefin together with carbon dioxide, whereas the generated amine is able to act as a catalyst for the fragmentation so that the carbamates are referred to as base amplifiers. Applications of acid and base amplifiers to photofunctional materials, including photoresists, are described as a consequence of the combination of the molecular amplifiers with photoacid as well as photobase generators. Practical applications of acid proliferation reactions in polymer films are discussed.
