- Synthesis of new macrobicyclic hexaamide ligands
-
A new two-step synthesis method of macrobicyclic hexaamide ligands LH6 (I and II) with double condensation of triethyl nitrilotriacetate and 1,4(1,2)-diaminobenzene was developed. The cyclization does not require high dilution and template techniques. Two new hexaamide ligands were prepared in good yields according to the proposed method.

- Connector ability to design superhydrophobic and oleophobic surfaces from conducting polymers
-
In the aim of creating superoleophobic surfaces using monomers with short perfluorinated chains, to avoid drawbacks associated with PFOA, original semifluorinated (C4F9, C6F13) 3,4-ethylenedioxypyrrole derivatives were synthesized. These monomers were obtained using the faster synthetic method than previously described with some analogues, characterized and electrochemically polymerized on gold plates. The obtained surfaces exhibited superhydrophobic (contact angle with water of 157° and 158°, respectively) and oleophobic properties (contact angle with hexadecane: 88° and 108°, respectively). The comparison between these new monomers and already published analogue EDOP6 confirms the importance of the bipolaronic form of conductive polymer for obtaining surface nanoporosity and as a consequence improving surface oleophobicity. Thus, little change in the molecule design of the connector and the spacer of the monomer can have a significant influence on the surface oleophobicity.

- Resist composition and patterning process
-
The present invention relates to: a resist composition such as a chemically amplified resist composition for providing an excellent pattern profile even at a substrate-side boundary face of resist, in addition to a higher resolution in photolithography for micro-fabrication, and particularly in photolithography adopting, as an exposure source, KrF laser, ArF laser, F2 laser, ultra-short ultraviolet light, electron beam, X-rays, or the like; and a patterning process utilizing the resist composition. The present invention provides a chemically amplified resist composition comprising one or more kinds of amine compounds or amine oxide compounds (except for those having a nitrogen atom of amine or amine oxide included in a ring structure of an aromatic ring) at least having a carboxyl group and having no hydrogen atoms covalently bonded to a nitrogen atom as a basic center.
