    摘要： Organic molecules can be coupled via their selenocarbonyl derivatives. Generally, the synthesis can be described by the following reaction equation: ##STR1## where C can be a cyclic or heterocyclic organic compound and R can be alkoxy, phenoxy or phenyl, preferably CH.sub.3 O, C.sub.2 H.sub.5 O, C.sub.6 H.sub.5 O, C.sub.6 H.sub.5 and the like. The reaction is usually carried out in a refluxing solvent, the choice of the solvent being determined by the stability and by the ease of coupling of a particular substrate. Groups that tend to stabilize the selenocarbonyl require higher boiling solvents and longer refluxing times. Aromatic solvents, such as benzene or toluene are well-suited for the coupling reaction. In some cases, refluxing the substrate in the alkoxy-phosphorus base as solvent may be advantageous. This new coupling procedure permits the synthesis of the hitherto unknown compounds: tetraselenofulvalene (TSeF), the selenium analogue of tetrathiofulvalene (TTF), and diselenodithiofulvalene (DSeDTF). Highly conducting charge transfer salts of tetraselenofulvalene and diselenodithiofulvalene with tetracyano-p-quinodimethane have also been prepared. The materials of this invention are useful in the organic electronic devices described in copending application Ser. no. 450,541 to Arieh Aviram et al. and assigned to the same assignee as is the present application.

    摘要： The invention is a cleaning cartridge which includes a housing and a tube for injecting a compressed gas therethrough and into specific areas of an optical disk drive. The tube is removably connectable at one end to a compressed gas supply, and is aimed at the other end to direct gas exiting therefrom at both the objective lens, beam-directing prism or mirror, or other internal optical disk drive components when the cartridge is seated in the drive. Upon insertion of the cleaning cartridge into the optical disk drive in the usual manner for any optical disk cartridge, gas is released from the compressed gas source, through the tube, and into the optical disk drive. The use of such a cleaning cartridge provides for easy, effective cleaning of any internal optical disk drive component without the abrasion and potential inconveniences associated with mechanical brushing, wiping, or other techniques.
