Fluorinated Styrene-Based Monomers for Cyclopolymerizations
No full textThe synthesis of versatile fluorine compounds and monomers for conducting polymer research and cyclopolymerizations is presented. Semiprotected 2,3,5,6-tetrafluoroterephthaldehyde 1 could be elaborated through Wittig olefination chemistry, deprotection and reduction to the previously unknown 4-vinyl-2,3,5,6-tetrafluorobenzylalcohol 8 in good yields. Compound 8 can be reacted to form the malonate ester, and then alkylation on the malonate moiety in mild conditions affords difunctional monomer 3. Through sequential esterifications on the malonate moiety, and subsequent alkylation, compound 4, a difunctional monomer for cyclopolymerization bearing one styrene and one perfluoroaryl styrene moiety, has been obtained. Preliminary experiments show that it is possible to cyclopolymerize 4 under free radical conditions

Mild Preparation of Functionalized [2.2]Paracyclophanes via the Pummerer Rearrangement
No full text[2.2]Paracyclophanes, incorporating functional groups in
the aliphatic bridges, suitable for elimination to give
[2.2]paracyclophanedienes, are synthesized through a novel
approach. It relies on a double Pummerer rearrangement on
dithiacyclophane precursors, followed by ring contraction
through a photochemical sulfur extrusion, and it is compatible
with aryl moieties possessing very different electronic
properties
Nanostructuring with chirality: binaphthyl-based synthons for the production of functional oriented nanomaterials
No full textChirality is a powerful tool for the generation of order, directionality, and, as such, of function, in assembled nanoscale chemical devices. Axially chiral binaphthyls have been widely used in organic synthesis; the stability of the enantiomers enables their use as robust chirality inducers and catalysts in asymmetric reactions, and they are nowadays industrially applied in a variety of organic transformations. Applications of these compounds in the field of nanosciences are more recent, and not yet fully explored. The integration of such a robust class of chiral compounds, capable of efficient transfer of stereochemical information, into functional aggregates and nanoarchitectures is of great current interest. We will discuss preeminent examples of applications of these synthons in several fields of nanoscience, such as reticular chemistry, non-linear optical materials and imaging, and liquid crystals
Controlled RAFT Cyclopolymerization of Oriented Styrenic Difunctional Monomers
No full textWe describe the first example of controlled free radical cyclopolymerization of difunctional styrenic monomers. The newly designed monomers are obtained from the introduction of two 4-vinylbenzyl moieties as malonate or dialkylated malonate esters. The more sterically hindered monomer is particularly efficient in the cyclization and propagation processes, giving cyclopolymers, in diluted solvent conditions, in good yields and degrees of polymerization. In the presence of a suitable RAFT mediator, and, upon careful optimization of the solvent, temperature and monomer concentration, linear increase of number average molecular weight with conversion and low polydisperisity indexes can be achieved
