GENERAL DESCRIPTION & APPLICATIONS

Dicyclopentadiene is co-produced with ethylene from the C5 fraction in the steam cracking of naphtha and gas oils. The largest consumption of dicyclopentadiene is linked to the production of resins including unsaturated polyester resins, petroleum resins, terpolymers, polynorbornenes, and other cyclic olefin polymers. It is used to manufacture pesticides, paints, varnishes, metal derivative, epoxy resin, adamantane, glutaraldehyde, perfumery, flame retardants, medicine, other chemicals.

Terpolymer is a polymer that contains three distinct monomers; ethylene, propylene, acrylonitrile, butadiene, styrene and dicyclopentadiene. ABS is the terpolymer of acrylonitrile-butadiene-styrene. EPDM (ethylene-propylene diene rubber) is the elastomer which is composed of ethylene, propylene and a nonconjugated diene which can be vulcanized. Norbornene is a bridged cyclic olefin. consists of a bridged cyclohexene with a solid bond on one side. It is prepared by the Diels-Alder reaction of two diene hydrocarbons, cyclopentadiene and ethylene. Norbornadiene which has the same carbon skeleton but with two solid bonds is produced from cyclopentadiene and an alkyne. Norbornane is a bridged cyclic hydrocarbon, saturated without solid bonds. Norbornenes are important monomers in ring-opening metathesis polymerizations (ROMP), radical and cationic polymerization, and addition polymerization. Polynorbornenes are polymers with high glass transition temperatures and high optical clarity. They also used in general organic synthesis for the target molecules including pharmaceutical intermediates, pesticide compounds, fragrances and high energy fuels. Endo, exo isomers are found in boat-shaped norbornyl systems. Endo is the prefix for the conformation of carbon bonds in a six-membered ring with one or more substituents directed inward from the ring (substituents positions are closest to the longest bridge). Exo is the isomer with the substituent of outward-directed valence bonds (shortest position the longest bridge).

GENERAL DESCRIPTION OF ORGANIC ELECTROLUMINESCENCE MATERIALS
Due to extended pi-electron cloud overlaps, organometallic molecules or aromatic oligometers such as anthracene exhibit semiconductor properties. Conductive polymers have extended delocalized bonds that creates electrical conductivity when charge carriers generated make positive charges (holes) and negative charges (electrons) move to opposite electrodes. Doping is the intentional impurities in a pure semiconductor to generate charge carriers. The transportation of charges is responsible for fluorescence and electrical energy. These can form well-ordered thin crystalline films. Organic semiconductors have some merits of self radiation, flexibility, light weight, easy fabrication, and low cost. Organic electroluminescence materials have lead to the rapid development of photovoltaic and display devices such as organic solar cells, biosensitizers, OLED(Organic Light Emiting Diode), OTFT(Organic Thin Film Transistor), Wearable Display, and e-Paper. Some examples of organic electroluminescence materials are:
  • Oligomer Electro Luminescence Materials
