Organic conductive materials are materials that are based on organic (carbon-based) compounds and exhibit electrical conductivity.
Unlike traditional conductive materials such as metals, organic conductive materials have unique properties that make them attractive for a wide range of applications, including flexible electronics, energy storage, and photovoltaics.
There are two main types of organic conductive materials:
One of the most commonly used semiconducting organic conductive materials is poly(3,4-
Despite these advantages, organic conductive materials have some limitations, including lower conductivity compared to traditional conductive materials and lower stability in certain environments. Nevertheless, ongoing research is focused on improving the properties of organic conductive materials to overcome these limitations and to expand their range of applications.
History
The history of organic conductive materials dates back to the early 1900s, when researchers first began investigating the electrical conductivity of organic compounds. However, it wasn't until the 1950s and 1960s that significant progress was made in the development of organic conductive materials.
One of the early milestones in the history of organic conductive materials was the discovery of the first conductive polymer, polyacetylene, in 1977 by Hideki Shirakawa, Alan J. Heeger, and Alan G. MacDiarmid. This discovery paved the way for the development of a new class of organic materials with metallic-like conductivity, which was a major breakthrough in the field of organic conductive materials.
In the decades that followed, researchers made significant progress in synthesizing and understanding the properties of a variety of organic conductive materials, including conductive polymers, doped conjugated polymers, and conductive oligomers. These materials have since found a wide range of applications in electronics, energy storage, and other fields.
One of the key areas of research in the history of organic conductive materials has been the development of new synthetic methods for producing these materials. This has led to the synthesis of a wide range of new organic conductive materials with improved properties and a broader range of applications.
In recent years, there has been a growing interest in developing organic conductive materials for use in flexible electronics, energy storage, and other applications. This has led to the development of new materials and processing techniques, as well as the commercialization of several new products based on organic conductive materials.
Overall, the history of organic conductive materials is a story of rapid progress and continued innovation, as researchers work to expand the range of applications for these materials and to improve their properties.
Metallic and Semiconducting.
Metallic organic conductive materials exhibit metallic conductivity and are typically composed of highly conductive materials such as gold or silver nanowires or flakes.
Semiconducting organic conductive materials, on the other hand, have an electronic bandgap that allows for the control of electrical conductivity through doping or other methods.
Organic conductive materials have several advantages over traditional conductive materials, including:
Flexibility: Organic conductive materials can be processed into flexible films, which enables the fabrication of flexible electronics and devices.
Light weight: Organic conductive materials are lighter than traditional conductive materials, making them well-suited for applications where weight is a concern, such as aerospace or wearable devices.
Low cost: Organic conductive materials can be synthesized from inexpensive precursors, making them more cost-effective than traditional conductive materials.
Environmentally friendly: Unlike traditional conductive materials, which are often synthesized from toxic or scarce materials, organic conductive materials can be synthesized from abundant, non-toxic materials.
