Abstract

The volume fraction plays an important role in phase segregated soft matters. We demonstrate here that at high fullerene volume fraction in soft chain-tethered-fullerene dyads, different two-dimensional (2D) crystal-constructed smectic-like lamella liquid crystalline (LC) phases can be formed with triple-layer (S phase) or quadruple-layer (S phase) stacking of fullerenes in 2D crystals. The combination of 2D crystal and LC properties in one system affords these fullerene dyads controlled electron mobility in the range of 10 -10 cm V s at room temperature (S phase), by regulating the insulated soft layer thickness between 2D crystals via the manipulation of fullerene volume fraction.

摘要

在相分离软物质中，体积分数起着重要作用。我们在这里证明，在软链接到富勒烯偶联物中富勒烯的高体积分数下，可以形成不同的二维（2D）晶体结构的类似层状液晶（LC）相，其中富勒烯在 2D 晶体中具有三层（S 相）或四层（S 相）堆叠。在一个体系中结合 2D 晶体和 LC 性质，通过调节富勒烯体积分数来控制 2D 晶体之间的绝缘软层厚度，可在室温下（S 相）将这些富勒烯偶联物的电子迁移率控制在 10 -10 cm V s 的范围内。
