For the surface-optoelectronic study of Saxitoxin sensing, we fabricated selfassembled calix[4]arene derivative monolayers as the recognition-functional interfaces on a gold surface. An interaction study between Saxitoxin and calix[4]arene derivative monolayers were performed using surface plasmon resonance (SPR) spectroscopy. Among three calix[4]arene derivatives, calix[4]arene crown ether SAM...

The reactions of [Cp*MCl2]2(Cp*=eta5-C5Me5, M = Rh, Ir) with thiacalix[4]arene (TC4A(OH)4) and tetramercaptothiacalix[4]arene (TC4A(SH)4) gave the mononuclear complexes [(Cp*M){eta3-TC4A(OH)2(O)2}] and the dinuclear complexes [(Cp*M)2{eta3eta3-TC4A(S)4}] respectively, while the analogous reactions with dimercaptothiacalix[4]arene (TC4A(OH)2(SH)2) produced the tetranuclear complexes [(Cp*M)2(Cp*...

(N(nBu)4)[MIIIL(acac)2], M = Y, Gd, Tb and Dy, have been constructed by combination of two O donor ligands, bidentate acetylacetone tetradentate p-tert-butylcalix[4]arene.

The dinuclear dichloro complexes [(g-arene)2Ru2(l-Cl)2Cl2] and [(g-C5Me5)2M2(l-Cl)2Cl2] react with 2-(pyridine-2-yl)thiazole (pyTz) to afford the cationic complexes [(g-arene)Ru(pyTz)Cl] (arene = C6H6 1, p-PrC6H4Me 2 or C6Me6 3) and [(g-C5Me5)M(pyTz)Cl] (M = Rh 4 or Ir 5), isolated as the chloride salts. The reaction of 2 and 3with SnCl2 leads to the dinuclear heterometallic trichlorostannyl de...

The functionalisation of macrocyclic p-tertbutylcalix[4]arenes at the lower rim with hydroxamic acid and proline hydroxamic acid groups gives the calixarenes chelating properties similar to siderophores. The (1)H NMR spectrum of p-tertbutylcalix[4]arene tetrahydroxamic acid shows a broad band at 10.8 ppm in DMSO-d(6) attributed to NHOH protons. Diffuse reflectance spectral analysis of PVC membr...

Reaction of Zn(C6F5)2·toluene (two equivalents) with 1,3-dipropoxy-p-tert-butyl-calix[4]arene (L(1)H2) led to the isolation of the complex [{Zn(C6F5)}2L(1)] (1), whilst similar use of Zn(Me)2 resulted in the known complex [{Zn(Me)}2L(1)] (2). Treatment of L(1)H2 with in situ prepared Zn{N(SiMe3)2}2 in refluxing toluene led to the isolation of the compound [(Na)ZnN(SiMe3)2L(1)] (3). The stepwise...
