Alkynyl pentacene derivatives of formula (I): wherein Ra is a solubilising group of formula (II) where R9 and R11 are C1-4alkyl, and R10 is hydrogen, C1-4alkyl or C1-3alkoxy; R1-R8 are hydrogen, fluorine or C1-4alkyl; may be useful to form organic thin films. The use of these solubilising group-containing pentacenes in electronic devices and components, for example organic field effect transistors or organic light emitting diodes, is also outlined. By providing specific C-alkyne side chains at the pentacene scaffold as solubilising groups and optional fluorine or alkyl substituents, compounds small molecule organic semiconductors that exhibit a high solubility and thermal stability during solution processing and at the same time show high field effect mobility and favourable π-π stacking may be manufactured. |
