摘　　要：20世纪80年代化学家Shechtman首次在快速冷却的铝锰合金中发现了准晶体,20年后科学家又在自然界中发现了软准晶体。此后,许多材料相继进入了软准晶系列,包括液晶、聚合物、纳米颗粒、胶体、介孔氧化硅等。这些软准晶材料在电子学、传感器、离子液体纳米反应器中具有潜在的应用。本文主要对能形成软准晶的树枝状分子、软准晶结构和准晶的应用前景进行了简要综述。In 1980s, Shechtman first discovered the quasicrystal in the rapid cooling of aluminum manganese alloy. 20 years later, scientists discovered the soft quasicrystal in nature. Thereafter, many mate- rials successively entered the soft quacicrystal series, including liquid crystal, polymer, nano particles, colloid, dielectric mesoporous silicon. These soft materials have potential applications in electronics, sen- sors, ionic liquid nano reactor. In this paper, dendrimers which can form soft quasicrystals, the structures of soft quasicrystals as well as the applications of soft quasicrystals are briefly summarized.
