The crystal packing of two charge-transfer complexes based on tetra-thiafulvalene and substituted fluorenes-2,4,5,7- tetranitro-9-dicyanomethylenefluorene or 2,7-dicyano-4,5- dinitro-9-dicyanomethylenefluorene were analyzed [9].

The 21 studies of this fourth volume include discussions of the disruption of alanine racemase gene of Schizosaccharomyces pombe, D-amino acid oxidase activity assays, the transformation of plants with D-amino acid resistance selectable markers, the resonance Raman study of charge-transfer complexes on porcine D-amine acid oxidase, and enzymes acting on D-amino acid amides.
Based on the experimental data obtained with the use of optical absorbance and luminescence spectroscopy as well as on the results of electrochemical and EPR measurements and the data of chemical analysis, we can conclude that the interaction of MDMO-PPV with heteropolyacids leads to the formation of strong charge-transfer complexes. This interaction does not cause irreversible destructive transformations in the polymer chain.
This ability allows these compounds to be used to make various polymerizable materials, including charge-transfer complexes and coordination compounds.
Various other thin films can be applied to the boundary liner to align the FLCs: Langmuir-Blodgett orientation films, metal-oxide thin films in combination with electric fields; and charge-transfer complexes doped with polyimide alignment layers.
