Based on Moore's Law, every 18 months the number of transistors that can be placed per unit area on a microchip will double. However, by the year 2017 this trend will cease to exist due to the size restrictions imposed by silicon, the main component of microchips; this has led to the birth of molecular electronics. An organic molecule that has been extensively tested for its potential in molecular electronics is DNA. However, recent research has shown that DNA cannot function as a molecular wire due to its fragile nature. This is why Raj Rathore's group is developing organic molecular wires based on robust macromolecular structures. The specific assembly designed to study the wire behavior consists of a triad which is made up of polyfluorenes as an electron donor site, a spacer unit (or wire) made of polyphenylenes, and an electron donor‐acceptor complexation site composed of hexamethylbenzene (HMB). A chloranil molecule—an electron acceptor—complexes with the HMB of the triad, and when a laser is shined on HMB/CA complex, a hole is introduced in the molecular wire which will travel 30 Å to the polyfluorene donor, via an electron hopping mechanism. The Marquette University High School SMART Team (Students Modeling A Research Topic) created a physical model of this molecular wire using 3D printing technology.
