The [2+4]cycloaddition of the novel A4B building block 2,3,4,5-tetrakis(4-triisopropylsilylethynylphenyl)cyclopenta-2,4-dienone 3 with 3,3â,5,5â-tetraethynylbiphenyl 1 allows the rapid synthesis of a spherical polyphenylene nanoparticle with 102 benzene rings.
新型 A4B 结构单元 2,3,4,5-四(4-三异丙基硅烷基乙炔基苯基)环戊-2,4-二酮 3 与 3,3â,5,5â-四乙炔基联苯 1 的[2+4]环加成反应可以快速合成具有 102 个苯环的球形聚苯纳米粒子。
