    Description / Table of Contents: The design and synthesis of molecularly or supramolecularly defined interfacial architectures have seen in recent years a remarkable growth of interest and scientific research activities for various reasons. On the one hand, it is generally believed that the construction of an interactive interface between the living world of cells, tissue, or whole organisms and the (inorganic or organic) materials world of technical devices such as implants or medical parts requires proper construction and structural (and functional) control of this organism-machine interface. It is still the very beginning of generating a better understanding of what is needed to make an organism tolerate implants, to guarantee bidirectional communication between microelectronic devices and living tissue, or to simply construct interactive biocompatibility of surfaces in general. This exhaustive book lucidly describes the design, synthesis, assembly and characterization, and bio-(medical) applications of interfacial layers on solid substrates with molecularly or supramolecularly controlled architectures. Experts in the field share their contributions that have been developed in recent years.

    Notes: Optical waveguide microscopy is used to image lateral heterogeneities of the electro-optic (EO) response of poled polymer waveguide structures. The sensitivity of the technique is demonstrated for a poly(methylmethacrylate) thin film doped with Disperse Red 1 between gold electrodes in a modified Kretschmann configuration. Even after aging of the poled polymer for one week, heterogeneities due to the anisotropy of the refractive index tensor can be distinguished from those owing to fluctuations of the EO coefficients.

    Notes: Surface-plasmon optical techniques (attenuated total internal reflection and surface plasmon microscopy, in particular) are employed to characterize the optical and structural properties of thin films of poly(methyl-phenyl-silane) in the thickness range d0=40–400 nm. Irradiation with deep UV light (90% at λ=253.7 nm) is shown to cause photovolatilization which results in a self-development of illuminated areas. The time dependence of this etching process is investigated, and substantial differences between irradiation in air or in an Ar atmosphere of 10−3 MPa partial pressure are found: For 40-nm-thick films in the presence of oxygen an ablation rate of 1.3 nm/min is derived for the first 5–10 min which drops rather abruptly to zero (irradiation power density ∼0.4 mW/cm2 ). In Ar atmosphere the etching rate is ∼0.1 nm/min but constant for more than 1 h. UV-absorption spectra and gel permeation chromatography are performed to gain some insight into the molecular mechanisms of these photochemical and photophysical differences which are of great importance for the photolithographic application of these materials.
