Abstract

The invention relates to novel compounds of formula (III) that can be used as heterocyclic dyes of unique structure and properties. These compounds can be obtained in a three-step synthesis from simple substrates. The compounds according to the invention have excellent solubility in organic solvents and excellent film-forming properties. In addition, high efficiency of energy conversion, excellent field-effect mobility, good on/off current ratios and/or excellent stability can be observed, when the compounds according to the invention are used in organic field effect transistors, organic photovoltaics (solar cells) and photodiodes.
