Abstract

Abstract: Many technological applications that have had tremendous impact on our society and lifestyle are exploiting the emission properties of organic species such as conjugated polymers and organic small‐molecule semiconductors. The most prominent case‐in‐point here are possibly organic light‐emitting diodes, which have found use in information displays, touch screens and beyond. To further advance the rapid development of these powerful and versatile technologies, it will be of paramount importance to gain fundamental insights about which strategies and processes we can employ to alter, control and eventually enhance the emission properties of this interesting class of material. In this work, we focus on macromolecular systems and review the most important categories of tools that can be employed to efficiently alter their emission properties by manipulating their molecular architecture and electronic structure; by influencing their molecular ordering, packing motifs and overall microstructure; as well as by utilizing the ability of some of these materials to respond to external stimuli and other physical parameters (pressure, light exposure etc.) and/or to interact with other compounds, including systems of different functionalities. © 2015 Society of Chemical Industry Abstract : Most important categories of tools that are nowadays employed by the scientific community in order to efficiently alter the emission properties of conjugated polymers can be divided into several main categories which include chemical design and molecular structure, physical processing tools, blending conjugated polymers with other organic or inorganic compounds as well as the use of metallic structures.
