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 (ST phase) or quadruple‐layer (SQ 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 10−5–10−3 cm2 V−1 s−1 at room temperature (ST phase), by regulating the insulated soft layer thickness between 2D crystals via the manipulation of fullerene volume fraction.

富勒烯体积分数对二维晶体构成的超分子液晶的影响

体积分数在相分离的软物质中起重要作用。我们在此证明,在富链富勒烯二聚体中富勒烯体积分数高的情况下,可以通过三层(ST相)形成不同的二维(2D)晶体构造近晶状层状液晶(LC)相或四层(S Q相)富勒烯在二维晶体中的堆叠。在一个系统中将2D晶体和LC特性相结合,可以在室温下将这些富勒烯二重体控制的电子迁移率控制在10 -5 –10 -3  cm 2  V -1  s -1范围内(S T 通过控制富勒烯体积分数来调节2D晶体之间的绝缘软层厚度。
