The development of new method to synthesize perfluoro[2.2]paracyclophane from reaction of 1,4-bis(chlorodifluoromethyl)-2,3,5,6-tetrafluorobenzene with Zn, heated in acetonitrile at 100 degree Celsius is reported. The study demonstrates the application of Perfluoro[2.2]paracyclophane for deposition experiments to determine the impact of perfluorination on properties of the respective parylene polymer.

The design and synthesis of two novel fluorine-boron cored fluorescent complexes are described. These complexes have exhibited well-ordered molecular packing, intense fluorescence and low LUMO levels, which are useful as electron-transport materials in electroluminescent (EL) devices.

The solid-state NMR studies of [([C.sub.2.5]F).sub.n] fluorine-graphite intercalation compounds (GIC) which converts to covalent graphite fluoride during a post-treatment in pure fluorine gas is reported. The results provide insight into hyperconjugation of the C-F bonds with neighboring unfluorinated carbon atoms.

The synthesis and the properties of the donor-acceptor containing polyfluorene derivative and its carbon nanotube composites prepared by Suzuki polymerization are described. These substrates are found to exhibit highly bistable electrical switching and a write-once read-many-times memory effect.

The syntheses, Raman spectra, and crystal structures of four new metal(II) hexafluorophosphates(V) containing Xe[F.sub.2] as ligands are described. It presents that Raman spectrum of the bulky belongs to the same compound that was structurally characterized.

The synthesis of a small molecule 4,7-di-2-thienyl-2,1,3-benzothiadiazole (DBT) dye is carried out which is further blended into blue-emitting polyfluorene as a host. The role of intra-and interpolymer chain interaction and energy transfer in the polymer light emitting devices are discussed.

A study reports that fluorinated phenoxide could be used to form stable, soluble compounds of Eu(II) and Eu(III) as well as a heterovalent dimer. Dative Ln-F interactions were noted with Eu(II) ions while Eu(III) ions were observed to adopt terminal phenoxide ligations and since phenoxides are soluble in apolar media, they are potentially useful as capping reagents in lanthanide cluster chemistry.

The reaction of Al[Cl.sub.3].3Py with [Me.sub.3]SiF aimed at the synthesis of [[Al[F.sub.2][(Py).sub.4]].sup.+][Cl.sup.-] and a room-temperature stable complex with a monomer molecular structure in the solid state is reported. The [super 27]Al MAS NMR spectrum of Al[F.sub.2]Cl.4Py has revealed an unexpected complexity due to the very large quadrupolar coupling constants (QCC) and can be resolved only at spinning rates above 25 kHz.

A 12-step synthesis of difluorodimethylproline derivative (S)-1 from commercially available trifluoroacetaldehyde methyl hemiacetal followed by a classical chemical resolution, provided enantiomerically pure 4,4-difluoro-3,3-dimethylproline derivative. The process dispenses with hazardous fluorination reagents, and gives an overall yield greater than 28%.
