Xe-atoms on Ni-surface (Don Eigler, 1989) Problem 1 Molecules are very small, hard to put together one by one
Problem 2 As they are so small, we must put together very many before we reach a macroscopic size A 1 x 1 x 1 mm sugar crystal contains 1,4 · 1018 molecules
Intermolecular forces Must be: • strong • Directional Two main types used in CE: • Hydrogen bonds • Metal coordination
MOFs • “Metal-Organic Frameworks (MOFs) are crystalline compounds consisting of metal ions or clusters coordinated to often rigid organic molecules to form one-, two-, or three-dimensional structures that can be porous”(from Wikipedia) MOF-5
Guanidinium derivatives Fumaric acid complex
Applications Construction of • polar materials for non-linear optics • molecular magnets • porous materials for storage • molecular sieves • sensors • molecule traps • biological model systems • catalysts • and much more
Biomarker identification Biomarker: A biological molecule found in blood, other body fluids, or tissues that is a sign of a normal or abnormal process, or of a condition or disease. A biomarker may be used to see how well the body responds to a treatment for a disease or condition. Also called molecular marker and signature molecule Present in small amounts = hard to identify
