DISTAL Dibromoresorcin[4]arenes Through Selective Deactivation: A Practical Optimization
Danielsiek, Dominic,Dyker, Gerald

A simple and straightforward regioselective synthesis of distal disubstituted resorcin[4]arenes was developed, avoiding competing substitution patterns at an early stage via regioselective deactivation. Product limiting reaction steps were optimized by st

A new class of supramolecular calix[4]resorcinarene substituted alkoxy side chain (-OC5H11, -OC8H17, -OC10H21) has been synthesized and well characterized. These supramolecular compounds were investigated by polarizing optical microscope (POM), differential scanning calorimetry (DSC), thermogravimmetric analysis (TGA) and high-temperature X-ray diffraction studies (XRD). The present synthesized supramolecular derivatives are promising to stabilize the hexagonal columnar phase over a broad thermal range. All the synthesized derivatives showed hexagonal columnar phase at lower temperature and showed enantiotropical nature. Compound 2a with small alkyl spacer on eight side showed higher thermal stability as compare to higher alkyl spacer substituted compounds 2b and compound 2c. These research results suggest that calix[4]resorcinarene was a good platform to construct bowl-shaped derivatives to exhibits the columnar liquid crystal phase and the observed liquid crystalline properties were greatly effected by the substituted alkoxy side chain on eight side of calix[4]resorcinarene skeletone. All the synthesized compounds were characterized by FT-IR, 1H NMR and 13C NMR spectroscopy.

Dendrimers were synthesized with phenyl and ferrocenyl-ended groups joined by vinyl moieties. All the dendrons used for dendrimers synthesis had showed trans configuration. This configuration as well as the 'cone' conformation of the resorcinarenes was preserved in the dendrimers, as it was shown by 1H NMR spectroscopy. The chemical structure and purity of the synthesized dendrimers were confirmed by 1H and 13C NMR, FAB+, MALDI-TOF, electrospray mass spectra, and elemental analysis. Cubic nonlinear optical behavior of this first generation of resorcinarene dendrimers was studied. The χ(3) values estimated from the THG Maker-fringe technique for the phenyl and ferrocenyl-ended resorcinarene dendrimers dispersed in thin solid films are of the order of 10-13 and 10-12 esu, respectively.
