  Oxacyclophanes based on a m-terphenyl framework

  摘要：

  m-Terphenyl tetraphenol 4 (Scheme I) and tetrabenzyl alcohol 19 (Scheme IV) were efficiently synthesized from 2,6-dichloroiodobenzene and an appropriate aryl Grignard, using tandem aryne technology. Each tetrol was used to construct bicyclic oxacyclophanes by linking the 3,3" and 5,5" substituents with bis-alkylating or acylating agents. Examples are 7, 14, 15, and 20-24. Only the meta isomer of xylylene dichloride formed a bicyclic oxacyclophane with 4; the ortho and para isomers gave polymers. However all three isomers gave oxacyclophanes (i.e., 10-12) with the diphenol 9 (only one link across the m-terphenyl framework) and bicyclic oxacyclophanes with 19 (i.e., 20-22), where each link contains two additional atoms. Para-linked 12 and 21 show restricted rotation of the p-xylylene rings. Two noninterconvertible conformers were obtained when the m-xylylene linking group contained a vicinal methoxy substituent (i.e., 15uu and 15ud).

  A radiation sensitive refractive index changing composition comprising (A) a decomposable compound, (B) a non-decomposable compound having a lower refractive index than the decomposable compound (A), (C) a radiation sensitive decomposer and (D) a stabilizer. By exposing the composition to radiation through a pattern mask, the above components (C) and (A) of an exposed portion are decomposed and a refractive index difference is made between the exposed portion and unexposed portion, thereby forming a pattern having different refractive indices.
