摘要
维数在有机半导体的电荷输运特性中起着重要的作用。虽然三维半导体,如硅,在无机材料中很常见,但赋予共价三维有机聚合物导电性是具有挑战性的。采用无催化剂Diels-Alder环加成聚合-酸促进芳构化法制备了三维π共轭多孔有机聚合物(3D p-POP)。三维p-POP的表面积为801 m2 g−1,整个碳主链完全共轭,经I2蒸汽处理后的电导率为6(2)×10−4 S cm−1,是一类新型永久多孔三维有机半导体的第一个成员。
A Three-Dimensional Porous Organic Semiconductor Based on Fully sp2-Hybridized Graphitic Polymer
Dimensionality plays an important role in the charge transport properties of organic semiconductors. Although three-dimensional semiconductors, such as Si, are common in inorganic materials, imparting electrical conductivity to covalent three-dimensional organic polymers is challenging. Now, the synthesis of a three-dimensional π-conjugated porous organic polymer (3D p-POP) using catalyst-free Diels–Alder cycloaddition polymerization followed by acid-promoted aromatization is presented. With a surface area of 801 m2 g−1, full conjugation throughout the carbon backbone, and an electrical conductivity of 6(2)×10−4 S cm−1 upon treatment with I2 vapor, the 3D p-POP is the first member of a new class of permanently porous 3D organic semiconductors.
