moiety is attached to a [2.2]paracyclophane skeleton, giving a catalyst with intrinsic planar chirality. Their synthesis is described starting from aminoparacyclophane 5 in four steps. In the course of this preparation, an unprecedented rearrangement involving a C-C bond insertion was observed, leading to an unexpected quinolone-phenyl[2.2]cyclophane (8). The target catalyst 16 was obtained in enantio-pure

The present invention provides a method of forming N-hydroxysuccinimide ester-functionalized paracyclophane. The present method is carried out by adding 4-carboxyl-paracyclophane into N,N′-Dicyclohexylcarbodiimide (DCC) and N-Hydroxysuccinimide (NHS) to form N-hydroxysuccinimide ester-functionalized paracyclophane. The present invention further provides a chemical film on a substrate and a method of forming the same, wherein the chemical film includes N-hydroxysuccinimide ester-functionalized poly-para-xylylene.

Fabrication of surfaces with reduced protein adsorption and/or cell adhesion comprising a vapor deposition coating process such that the coating includes polymer interfaces containing chemical groups reducing the protein adsorption and/or cell adhesion. The invention allows precise anchoring and presentation of biomolecules in their biological context. The resulting systems comprise superior surfaces for design of protein- or cellbased bioassays, because of high-signal-to-noise ratios. Background adsorption is suppressed while specific interaction with capturing molecules is not affected.
