Test your memory: Two organic small molecules TPA-2BIPs and TPA-3BIPs have been synthesized and characterized. Sandwich-structure memory devices made from these molecules show that the two materials have similar switching behavior but different ON/OFF ratios. AFM images analysis and molecular simulation indicate that increasing the numbers of acceptors change the stacking of molecules in the solid state, but have less effect on switching behaviors of as-prepared memory devices.
