摘要:A method of making a fluorothieno[3,4-b]thiophene derivatives and photovoltaic polymers containing same using 3-bromothiophene-2-carboxylic acid as a starting material. This synthetic route provides an easier synthesis as well as greater yield and a purer product, which produces superior results over the prior art less pure products. The resulting materials can be used in a variety of photovoltaic applications and devices, especially solar cells.

摘要:A hydroxyl-containing monomer of formula (1) is provided wherein R 1 is H, F, methyl or trifluoromethyl, R 2 and R 3 are monovalent C 1 -C 15 hydrocarbon groups, or R 2 and R 3 may form an aliphatic ring. The monomers are useful for the synthesis of polymers which have high transparency to radiation of up to 500 nm and the effect of controlling acid diffusion so that the polymers may be used as a base resin to formulate radiation-sensitive resist compositions having a high resolution.
