Chemistry: New Era for Organic Semiconducting Polymers

Semiconductor polymer, polythiophene introduced poly (acetylene) discovery; conjugated polymer opened the way to a new era of organic semiconductor polymers in 1977. 1,2 Easy processing, low cost mechanical flexibility, low weight and high absorption coefficient of these conjugated organic semiconductor polymers makes it a promising candidate for applications. Organic field effect transistor (OFET), bulk heterojunction (BHJ) solar cell and organic light emitting diode (OLED). 1,3 have been extensively studied over the past few decades to study new conjugated materials. Increase efficiency and cost of BHJ solar cells

Semiconductor polymers have a wide range of applications in organic electronics, such as solar cells, thermoelectric devices, LED displays, but excitons and polaron dynamics that determine the efficiency of these devices are not well understood, especially in chains. And chain dynamics. . Accordingly, we have developed a polymer system in an ordered mesoporous silica film which allows separation of small amounts of polymer chains and elongation of the polymer backbone. Since the optical transition in the polymer occurs along the backbone, our system allows the use of polarization spectroscopy to detect interchain interactions and interchain interaction, respectively. By using various polymers including push-pull polymers in this mesoporous silica system, we can use optical studies to understand chain conformation and polymerization effect for all kinds of semiconductor polymers.

In the section on chemical and organic chemistry, we understand various polymers, monomers, elastomers etc. The monomer is a single unit, and when a large amount of monomer is combined or polymerized, a polymer is formed. The process by which monomers are converted to polymers is that the elastomer is another type of polymer with special properties of restoring its structure, even if it is stretched. Rubber is elastomer. Rubber has many uses in general life. An important property of rubber is that it restores its structure even if it is stretched. Stretching can reach certain limits. When it goes beyond the limit, it breaks

Carbon organic chemistry is research on carbon compounds. The diversity of the molecular structure of carbon provides the broad properties of the compound. How are polymer - polymers made and why are they different? Research has been done on how chemists control the molecular structure to produce polymers with specific properties. For a long time, we have been recognized as an indifferent group of indifferent countries. And now, we recognize that Central America is an important and constantly changing region, and that all countries observe their own identity. This film explains the basic outline of the cultural and social geography of this region and clarifies similarities and differences between the seven countries.
