利用单个分子制造电子器件一直是分子电子学的最终目标。特别是对于二进制数据存储，挑战一直是以简单和可重复的方式在两种状态之间切换单个分子的能力。证明了氯铝酞菁（ClAlPc）偶极分子的单分子在紧密堆积的单层内的可逆开关。通过脉冲扫描隧道显微镜尖端，读写操作的单分子二进制位在类似于40 Tb/cm 2（类似于250 Tb/in 2）的演示。
Making electronic devices using a single molecule has been the ultimate goal of molecular electronics. For binary data storage in particular, the challenge has been the ability to switch a single molecule in between bistable states in a simple and repeatable manner. The reversible switching of single molecules of chloroaluminum phthalocyanine (ClAlPc) dipolar molecules within a close-packed monolayer is demonstrated. By pulsing an scanning tunneling microscopy tip, readwrite operations of single-molecular binary bits at similar to 40 Tb/cm2 (similar to 250 Tb/in2) are demonstrated.
