一种用于有机电子材料开发的强大受体砌块

3,7-二氢苯并[1,2-b:4,5-b']二呋喃-2,6-二酮 (1)是一种用于π-共轭聚合物开发的强大的电子受体砌块。一些包含1的受体单元制成的聚合物已被报道用于具有高电子迁移率的n型有机场效应晶体管 (OFET)材料^1-3)。1还作为有机热电子材料砌块而受到关注，并且已经开发出电导率超过10 Scm⁻¹，高功率因数超过10 μWm⁻¹K⁻²的有机热电子材料^4,5)。这些高性能被认为是通过深度最低未占据分子轨道 (LUMO)能级和良好的π-π堆叠的有效n型掺杂来实现的^4,5)。此外，据报道，通过1的氧化聚合和随后的n型掺杂，合成了一种电导率超过2000 Scm⁻¹的高导电性和可溶液加工的n型导电聚合物^6,7)。
