The structural state of dendritic macromolecules at air-water (Langmuir mono-layers) and air-solid (adsorbed monolayers, self-assembled films and cast films) interfaces have been reviewed by Tsukruk [17]. Although this work summarizes various characterization techniques for dendritic films by AFM techniques, in this chapter, we will present recent progress on the characterization of the dendritic film surface morphologies.

The X-ray diffraction (XRD) measurements for 7a have been performed to examine the relationship between the photoluminescent properties and the self-assembled structures (Fig. 9). The XRD pattern of 7a in the Sm3 phase shows several diffractions in the small angle region, corresponding to (100), (200), (300), (400), and (500) reflections. The layer spacing is similar to the molecular length calculated to be 82 A. It is assumed that monolayer self-assembled structures are formed in the Sm3 phase (Fig. 9, top). In the SmA phase, only one peak appears at 38.2 A in the diffraction pattern obtain at 120 °C. The layer spacing is less than half...

Realization of two-terminal microsensors like that represented in Scheme I depends on the discovery of viable reference and indicator molecules that can be confined to electrode surfaces. Described herein are three different microelectrochemical sensing systems. The first is a three-terminal microelectrochemical sensing system for CO based upon an indicator molecule, ferrocenyl ferraazetine, that selectively reacts with CO (2). The second microelectrochemical system is based upon a disulfide functionalized ferrocenyl ferraazetine that can be adsorbed onto Au or Pt via monolayer self-assembly techniques. Efforts to make a two-terminal CO sensor based upon the... 

A CO Sensor Based Upon Self-assembled Ferrocenyl Ferraazetine. Having demonstrated the CO dependent solid-state electrochemistry of ferrocenyl ferraazetine, we synthesized a ferrocenyl ferraazetine molecule with disulfide functionality (Id). Scheme III. The specific aim was to design a CO sensitive molecule that could be confined to the working electrode of a two-terminal device via monolayer self-assembly techniques. Disulfides have been shown to irreversibly adsorb to Au and Pt surfaces (3-10). NMR and mass spectrometry are consistent with the proposed structure for compound Id. The FTIR spectrum of Id in THF exhibits metal carbonyl bands at 2067,2024,1989,1985 cm similar to the spectra for other ferraazetine derivatives la-c (2,5-6). Like derivatives la-c. Id reacts with CO (1 atm) at 298 K in CH2C12 to form a ferrapyrrolinone complex 2d, equation (3).

As distinct from sohd supports such as gold or silver, mercury imparts lateral mobihty to hpid monolayers directly self-assembled on its surface, because of its liquid state. This is demonstrated by rapid spontaneous phase separation, with microdomain formation, in a hpid mixture monolayer self-assembled on top of a DPTL thiolipid monolayer tethered to a mercury microelectrode [30]. The presence of microdomains was directly verified from the images of the distal hpid monolayer obtained using two-photon fluorescence lifetime imaging microscopy.

Time dependencies measured in Ref. 26 showed that the adsorption of lipid at the ITIES is fully reversible. The lipid adsorption on and desorption from the ITIES occur at about the same time scale. The monolayer self-assembled at the ITIES is in dynamic equilibrium with dissolved lipid molecules that allows any pinhole defects to be healed. In contrast, self-assembly on the solid/liquid interface often involves irreversible adsorption and requires high purity of chemicals, complex pretreatment, and preparation protocols to obtain a low-defect-density molecular monolayer (32).
