Abstract
Organic electronics develops very fast due to elaboration of novel functional materials, improving their processing techniques and appearance of new device architectures. Such development requires that many researchers of this multidisciplinary field working in different countries in the world should understand each other in terms of nomenclature of the materials, terminology of the phenomena investigated and as well as comparability of the results obtained. This tutorial lecture aims to cover some main standards and guidelines for good practice in organic electronics and highlight the sources where they can be found. Terminology and nomenclature for different materials is elaborated for many years by the corresponding experts in the International Union for Pure and Applied Chemistry (IUPAC). Nowadays it has a collection of Color Books, which cover different aspects of chemistry and related phenomenon. Since organic electronic materials includes organic molecules and polymers, the most important are Blue book and Purple Book named as “Nomenclature of Organic Chemistry” and “Compendium of Polymer Terminology and Nomenclature”, respectively. General “Compendium of Chemical Terminology” is covered by Gold Book, which is available online as a free interactive version. For those who are new in the field, several Brief Guides for Organic, Inorganic and Polymer Nomenclature are available and the new version are elaborated. The IUPAC publish Technical Reports and Recommendations in the journal “Pure and Applied Chemistry”. One of the recent publications important for organic electronics is “Glossary of terms relating to electronic, photonic and magnetic properties of polymers (IUPAC Recommendations 2021)”. The experts continue to work on various aspects of terminology and nomenclature relevant to organic electronics and the new recommendations are to be published soon. One of the most important standards for organic light emitting devices is CIE 1931 color space. It was developed by the International Commission on Illumination (CIE) in 1931 and widely used for the estimation of the color purity, which define the relationship between the visible spectrum and human color vision. Since that time some other corrections have been elaborated, but still CIE 1931 color space is the most widely used. For estimation of the device efficiency in organic photovoltaics the most important is the standard 1.5G, implying the power of 100 mW/cm2 under the solar light spectrum appeared to the earth surface passed through 1.5 air mass atmosphere. Last but not less is testing of the device efficiency in the certified laboratories under the standard conditions. These and other examples of the standardization will be considered.
