Redox properties of Bis-Triarylamines and ligand properties of Thianthrenophane
… relaxes in a symmetry broken CT state. The [2.2]paracyclophane bridged dimer is an example for a weakly coupled system, because the spectroscopic behavior is very similar to the corresponding p xylene monomer. In contrast, anthracene as well as p-xylene bridges mediate a stronger coupling and …

ALKYLATION AND OXIDATIONS OF SYMMETRICAL DIMETHYLENEBIPHENYL AND RELATED DIANIONS (CYCLOPHANE, BIPHENYLOPHANE, NMR, CONFORMATION).
… and n.0.n.0 cyclophanes. An X-ray study on 14.0 paracyclophane showed it to have a conformation different from that observed in solution by NMR; MM2 calculations were used in determining what the solution conformation is likely to be. Oxidation of the dianions produced the monomer …

Molecular Encapsulation of Conjugated Polymers for Organic Electronics
… Specifically, the study centeres on [n]paracyclophane-based ([n]PC) conjugated polymers, designed to investigate various effects. These include altering the cyclophane chiral centre by changing the ansa unit, modifying the polymer morphology by changing the side chains, and varying the …

Systematic Investigation of Intermolecular Interactions in NEXAFS Spectroscopy
… were systematically studied by using paracyclophane (PCP) molecules, in which the benzene/benzene separation distance can be systematically varied through the length of the spacer between benzene rings. The effects of Rydberg quenching on the degree of Rydberg-valence mixing in …

Single Molecule Junction Conductance and Binding Geometry
… well-defined conductance is also obtained with paracyclophane molecules which bind to gold directly through the ð system. Next, we are able to create metal-molecule-metal junctions with more than one reproducible conductance signatures that can be accessed by changing junction geometry. In the …

Novel Low Dielectric Constant Thin Film Materials by Chemical Vapor Deposition
… from 4,5,7,8,12,13,15,16-octafluoro-[2.2]-paracyclophane (DVT-4). The main motivation was to find a cheaper alternative to poly( alpha, alpha , alpha ', alpha '-tetrafluoro-p-xylylene) (AF-4) with similar properties. The dielectric constant of VT-4 was measured as 2.42 at 1 MHz, and the …
