(Chemical Equation Presented) Two new tetraphenylethylene (TPE) compounds 1 and 2 bearing adenine and thymine moieties, respectively, were found to be fluorescence "turn on" chemosensors for Ag+ and Hg 2+ by making use of the AIE fea

A novel selective and sensitive fluorescence 'on-off-on' probe based on tetraphenylethylene (TPE) motif for sequential recognition of Fe3+ and Hg2+ in water has been developed. Especially the complex 6-Fe3+ could behave as a 'turn on' fluorescent sensor over a wide-range pH value for detection of Hg2+. The selectivity of this complex for Hg2+ over other heavy and transition metal ions is excellent, and its sensitivity for Hg2+ is at 2 ppb in water.

We have developed a new fluorescent sensor 1-2Zn based on a tetraphenylethylene (TPE) moiety for the detection of PPi. This TPE-based chemosensor showed 'turn-on' fluorescence emission according to the concentration of PPi. The fluorescence enhancement upon binding of PPi to 1-2Zn resulted from the restriction of intramolecular rotation of phenyl rings in 1-2Zn.

4,4′-Dihydroxybenzophenone was used as a precursor for synthesis of macrocyclic compounds. Low-temperature crystal structures were determined for 4,4′-diethoxybenzophenone (10), C17H18O3, orthorhombic, Pbcn, a = 7.2891(12), b = 6.2827(10), c = 31.1000(5) A, Z = 4 (one molecule with twofold symmetry), and 1,5,19,23-tetraoxa-12,30-dioxo[5.1.5.1]paracyclophane (6), C34H32O6, triclinic, P(-1), a = 9.1559(12), b = 11.634(2), c = 14.124(2) A, α = 93.745(12), β = 102.966(10), γ = 108.591(12)°, Z = 2, (two independent molecules each with inversion symmetry). The interplanar angles between aromatic rings is 53° for compound 10 and 53°, 49° for the two molecules of 6. IR , Raman and UV spectra were recorded for both compounds. Key words: tetraoxaparacyclophanes, benzophenone, preparation, crystal structure, IR and Raman spectra.
