Self-Assembled Poly(4-vinylpyridine)−Surfactant Systems Using Alkyl and Alkoxy Phenylazophenols

Alkyl vs. alkoxy chains on ionic liquid cations.

The crystal structures and thermal behavior of the 1-(2-methoxyethyl)-2,3-dimethylimidazolium chloride and hexa-fluorophosphate salts are compared with the analogous 1-butyl-2,3-dimethylimidazolium salts to examine the influence of the ether oxygen on salt thermal properties for a typical constituent cation used in the preparation of ionic liquids.

Complement-Based Self-Replicated, Self-Assembled Systems (CBSRSAS)

Self-replication of CBSRSAS may occur as a result of completing the complementary parts of the system or self-assembly of the whole system. Self-replication process is a timeconsuming process that depends on the dynamics of the system components and environmental factors that describe how system components are distributed across the media and how viscous is the media when the viscosity of the m...

Self Assembled Nano-Devices Using DNA

Self-assembled monolayer films derived from tridentate cyclohexyl adsorbates with alkyl tailgroups of increasing chain length.

Tridentate cyclohexyl-based alkanethiolate SAMs generated from a series of adsorbates of the form R3C6H6(CH2SH)3, where R = -(CH2)nH and n = 3, 8, and 13 (3CnCyTSH), were examined. Characterization of the SAMs by X-ray photoelectron spectroscopy (XPS) revealed that all sulfur atoms of the tridentate adsorbates were bound to the surface of gold, and that the tailgroups were in general less dense...

Loosely packed self-assembled monolayers on gold generated from 2-alkyl-2-methylpropane-1,3-dithiols.

A series of 2-alkyl-2-methylpropane-1,3-dithiol derivatives with increasing alkyl chain lengths (i.e., CH3(CH2)mC(CH3)[CH2SH]2, where m = 7, 9, 11, 13, 15) were synthesized and used to generate self-assembled monolayers (SAMs) on gold. The resulting monolayers were analyzed by ellipsometry, contact angle goniometry, polarization modulation infrared reflection-absorption spectroscopy, and X-ray ...
