Surface and Colloid Science

In order to enable optical systems to operate with a high degree of compactness and reliability it is necessary to combine large number of optical functions in small monolithic structures. A development, somewhat reminiscent of that that took place in Integrated Electronics, is now beginning to take place in optics. The initial challenge in this emerging field, known appropriately as "Integrated Optics", is to demonstrate the possibility of performing basic optical functions such as light generation, coupling, modulation, and guiding in Integrated Optical configurations. The talk will review the main theoretical and experimental developments to date in Integrated Optics. Specific topics to be discussed include: Material considerations, guiding mechanisms, modulation, coupling and mode losses. The fabrication and applications of periodic thin film structures will be discussed.

Methods for Selective Modifications of Cyclodextrins.

Several different cyclodextrinthiol derivatives have been immobilized on gold surfaces through a chemisorption process to form films which exhibit significantly different features. Three monothiolated cyclodextrin derivatives with different spacers between the cyclodextrin cavity and the thiol group and a mixture of multithiolated cyclodextrins were synthesized and characterized. Chemisorption of these compounds onto gold surfaces gave films which were investigated by Fourier transform infrared (FTIR) spectroscopy, time-of-flight mass spectrometry, contact angle measurements, plasmon surface polariton (PSP) spectroscopy, and cyclic voltammetry. It was found that the chemical structure of each cyclodextrin derivative had a strong influence on the molecular architecture in the resulting films, and in particular on the orientation of the cyclodextrin torus. Models were developed to describe the molecular arrangement in the films.

Specific bio-recognition reactions observed with an integrated Mach-Zehnder interferometer.

In a previous paper we could demonstrate the immobilization of mono- and multithiolated cyclodextrins on gold surfaces and investigated the film properties. In this paper we follow the self-assembly processes in time by optical and physicochemical methods for those three monothiolated and a mixture of multithiolated cyclodextrin derivatives. The formation of cyclodextrin films on gold substrates was found to be a multistep process involving an activation energy.

In previous papers we have demonstrated the immobilization of thiol-functionalized cyclodextrins on gold surfaces We have studied the film properties and kinetics of the formation of covalently bound monolayers In this paper we focus on the guest-host interactions with immobilized cyclodextrins Four guest molecules are taken into account: the redox couple ferro-/ferricenecarboxylic acid, 4-tert-butylbenzoic acid, cyclohexanol and the electro-optically active dye methyl orange
