摘　　要：基于有机π共轭体系的一维自组装微纳米材料(1D-MNMs)具有较少的散射电荷传输、尺寸适中、易于制备等优点,可以方便地构筑集成微电路.虽然基于p沟道或n沟道有机半导体的一维自组装微纳米材料已经取得了巨大的进展,但遗憾的是,迄今为止,基于双极性有机半导体的一维自组装微纳米材料还非常缺乏.本文利用物理气相传输法,制备了基于6,13-双氰基并五苯(DCP)的一维滑移堆积新型自组装微纳米材料,其表现出良好的双极性电荷传输特性,电子和空穴迁移率分别达到0.34和0.38 cm2 V^(-1)s^(-1),是一维自组装微纳米材料中最好的双极性电荷传输特性之一.此外,基于双极性DCP的一维自组装微纳米材料构建了互补型反相器,增益可达7,表明其在有机逻辑电路中具有潜在的应用前景.Featuring small charge transport scattering,mesoscale size,and easy fabrication,one-dimensional self-assembled micro/nanomaterials(1D-MNMs)based on organicπ-conjugated systems can be facilely incorporated into integrated microcircuits.Although tremendous progress has been made in 1D-MNMs based on p-or n-channel organic semiconductors,examples of 1D-MNMs based on ambipolar organic semiconductors are scarce.Herein,we achieved a novel 1D-MNM based on 6,13-dicyanopentacene(DCP)with a 1D slipped stacking motif using the physical vapor transport method.The DCP-based 1D-MNM showed outstanding,wellbalanced ambipolar charge transport with electron and hole mobilities of up to 0.34 and 0.38 cm~2 V^(-1)s^(-1),respectively,which are among the best ambipolar transport characteristics of 1D-MNMs.Furthermore,a complementary inverter based on the ambipolar 1D-MNM of DCP was also constructed with a gain of up to 7,indicating potential application in organic logic circuits.
