"But if I can take a single organic molecule and learn how it hydrogen-bonds to different kinds of molecules, I then can put it into a solid and surround it with molecules different from itself." In one example, Etter and her co-workers start with the molecule para-nitroaniline -- used for making dyes -- and assemble it with other molecules into 25 different crystals, or solid states, each with unique optical and electronic properties.
