method using chiral N-heterocyclic carbene (NHC) as the sole organic catalyst to synthesize planarchiral carbonitriles asymmetrically, resulting in optically pure, multifunctional compounds. The method demonstrates remarkable tolerance toward diverse substituents and substitution patterns through kinetic resolution (KR) or desymmetrization processes. The resulting optically pure planarchiral products
Multifunctional reactive polymers created by chemical vapor deposition (CVD) and methods of making such polymeric systems are provided. Such polymers provide multifunctional surfaces which can present two or more different molecules (e.g. biological ligands) in controlled ratios. Polymers may include compositional gradients allowing attached ligands to be presented as continuous gradients across a surface. The polymer compositions are modularly designable and applicable to a wider range of applications, including biomedical devices and diagnostic systems.
