Synthesis of Air-Stable Cyclopentadienyl Fe(CO) (Fp) Polymers by a Host-Guest Interaction of Cyclodextrin with Air-Sensitive Fp Pendant Groups.

Host-guest chemistry is used to address the challenge of the synthesis of air-stable polymers containing air-sensitive metal complexes. The complexation of the CpFe(CO) (Fp) pendent group with cyclodextrin (CD) molecules created air-stable poly(Fp-methylstyrene) P(CD/FpMSt). This CD complexation resulted in dimerization of the adjacent Fp groups, which was characterized by NMR, FTIR, and cyclic voltammetry (CV) analyses.

Electrochemical synthesis on single cells as templates.

The cell surface is made electrochemically active by interfacing with graphene sheets. The electrical and thermal properties of graphene allow the control of cell surface potential for electrochemical synthesis. Using this approach radially projecting ZnO nanorods are templated on the surface of single cells.

Graphene as membrane for encapsulation of yeast cells: protective and electrically conducting.

Graphene sheets (chemically reduced), a high modulus and high thermal and electrically conductive material are coupled with yeast cells to form an encapsulating inorganic functional layer. The coupling of the high modulus sheets with the cells increases their stability to osmotic stresses. The sheets also allow the direct visualization of the cells in an electron microscope.
