Organic light emitting devices the emissive layer comprises a host material containing a fluorescent or phosphorescent emissive molecule, which molecule is adapted to luminesce when a voltage is applied across the heterostructure, wherein the device comprises an electron transporting layer comprising a derivative of cyclooctatetraene.

Cyclooctatetraenes as electron transporters in organic light emitting diodes

The synthesis of asymmetric tetrasubstituted cyclooctatetraenes (&ldquo;COTs&rdquo;) and the use of said compounds in organic light emitting diodes is reported, wherein said COTs represent a class of wide gap electron transporters that are readily deposited in vacuum.

Synthesis of cyclooctatetraene derivatives and their use as electron transporters in organic light emitting diodes

This invention relates to new fluoroalkyl substituted cyclotrisiloxanes, their use in the preparation of new homopolymers, block copolymers and random copolymers, and to such new homopolymers, block copolymers and random copolymers.

Fluoroalkylsubstituted cyclotrisiloxanes, their use for preparation of new polymers and novel polymers

This invention relates to methods for the preparation of hyperbranched siloxane polymers by anionic polymerization of a cyclotrisiloxane having the functional group Si&mdash;OH, and for the preparation of linear siloxane polymers by cationic or anionic polymerization of a cyclotrisiloxane having a vinylterminated functional group. Furthermore, this invention concerns novel cyclotrisiloxanes useful for the preparation of the aforementioned polymers.

Cyclotrisiloxanes, new siloxane polymers and their preparation

Polycarbosilane polymers are prepared from 1,3-butadiene or substituted 1,3-butadiene by reacting the butadiene with a dichlorosilane in the presence of a reducing metal. The polymers contain silicon hydride or other crosslinkable groups in the polymer chain.

Carbosilane polymers prepared from butadiene

Poly(1-hydro-1-R-1-silapent-3-ene) homopolymers and copolymers contain silane segments with reactive silicon-hydride bonds and contain hydrocarbon segments with cis and trans carbon-carbon double bonds.

Cross-linkable poly(unsaturated carbosilane) homopolymers and copolymers

Crosslinkable carbosilane polymer formulations are prepared from saturated or unsaturated carbosilane polymers containing reactive silicon hydride radicals in the polymer chain combined with polycyclic polyene crosslinkers having two or more double bonds that are reactive in the hydrosilation crosslinking reaction.

Crosslinkable carbosilane polymer formulations

An apparatus and method for jumping or charging a discharged automobile battery in order to start an automobile. Jumper cables are provided having indicator lamps to insure correct polarity connecting of cables. A switch, controlled manually or by timer establishes connection between the charged and discharged battery to charge the latter for a predetermined period of time. A circuit breaker to automatically disconnect the circuit in a situation where a dangerously high content would flow.
