Figure 1: Structures of donor (red)–acceptor (blue) functionalized molecular wires. The molecules are based on a central oligo(phenyleneethynylene) (OPE3) core with acetyl (Ac) protected thiolate end groups for electrode anchoring. Dithiafulvene (DTF) is used as the donor unit. Protonation of...
To observe NMR invisible species, the chemical exchange saturation transfer (CEST) technique was developed to probe the exchange kinetics between free molecules in solution and molecules bound to the surface of large supramolecular structures [169]. CEST-NMR experiments demonstrated that α-Syn ...

Solution Studies of Ru2(O2CR)4n+ Complexes (n = 0, 1; O2CR = Octanoate, Crotonate, Dimethylacrylate, Benzoate, p-Toluate) and Solid-State Structures of Ru2... Ru2(O2C(CH2)6CH3)4 (1a) is soluble in both coordinating (THF, CH3OH, CH3CN) and noncoordinating solvents (benzene, tol...
Resonance Raman spectra were recorded from methyl red, ethyl red and α-naphthyl red adsorbed from toluene solutions on to γ-alumina. The spectra show clear evidence for the protonation of all three indicators. Adsorption data over a wide range of equilibrium concentrations give satisfactory fits ...
Electron Paramagnetic Resonance Spectroscopic Characterization of α,2- and α,4-Didehydrotoluene The elusive diradicals α,2- and α,4-didehydrotoluene 1 and 3, have been generated by photolysis of matrix-isolated 2-iodobenzyl iodide 7 and 4-iodobenzyl iodide 8, respectively. Diradical 3 coul...
Fig. 1: Molecular structures and electron spin resonance spectra. aSchematic diagram depicting the zero-field splitting (ZFS) of the lowest-lying triplet state (T1) into its three sublevels (Tx,y,z). The magnitude of the ZFS parameters,DandE, describes the splitting of the triplet sublevels...
A series of novel 9-(4-substituted)phenoxy-naphthaceno[5,6-bc]pyran-2,8-diones were synthesized and their structures were confirmed using elemental analysis and the IR, 1H NMR and MS spectra. The photochromism of these compounds was observed in DMSO, DMF, CH2Cl2, CHCl3, benzene and toluene...
