Synthesis of Supercritical Carbon Dioxide Soluble Perfluorinated Dendrons for Surface Modification
摘要:
The rational design, synthesis, and characterization of a series of novel perfluorinated dendrons 14a,b, 25a,b, 26a,b, and 18 are described. The dendrimers were designed to have a thiol at the focal point for attachment to a gold surface to enable the fabrication of self-assembled monolayers (SAMs). Perfluorinated tails were attached to the periphery to provide solubility in supercritical carbon dioxide, and to increase the hydrophobicity and the stability of self-assembled monolayers formed. Mitsunobu reactions were utilized to provide high-yielding steps allowing large-scale production of the novel dendrimers.

Aldehydes R-F(CH2)(m)CHO (R-F=n-CnF2n+1) have been prepared in good yields by oxidation of the corresponding alcohols using inexpensive and safe oxidants such as phenyliodine (III) diacetate and trichloroisocyanuric acid in the presence of 2,2.6,6-tetramethyl-1-piperidinyloxyl free-radical (TEMPO) as a catalyst.

Chirality Induction through Nano‐Phase Separation: Alternating Network Gyroid Phase by Thermotropic Self‐Assembly of X‐Shaped Bolapolyphiles
single gyroid phase as well as the alternating double network gyroid, composed of two alternating single gyroid networks, hold a significant place in ordered nanoscale morphologies for their potential applications as photonic crystals, metamaterials and templates for porous ceramics and metals. Here, we report the first alternating network cubic liquid crystals. They form through self‐assembly of X‐shaped
