1. Three molecules with potentially useful properties in molecular electronics are given below. Select the optimum molecule to carry out each of the three functions below. Describe your reasoning, including the specific molecular properties that lend themselves to that application and how the device would function: Switching of electron flow (current on/off) Information storage. Wire (connect) two molecular electronic components so that electrons can flow between them. C3H17 wy C8H17 In) C3H17 Poly(3-alkyl Thiophene), a polymer with molecular weight of 450,000 gmol [Ru(bpy)zQbpy]2+, where bpy is 2,2'-bipyridyl and Qbpy is 2,2":4,4":44"-quarterpyridyl (pyridine binds strongly to metals such as gold or platinum and undergoes reversible Ru2+/3+ redox chemistry and emits at 610 nm). R R N UV X 0- Vis and (or) A Closed Form Open Form Spiropyran, a molecule whose conformation can be changed by light, potential or heat
