Abstract

The invention relates to an electronic device comprising a compound having Formula (1): ABx (1), wherein A is a structural moiety that consists of at least two atoms and comprises a conjugated system of delocalized electrons, each B is independently selected from an imine functional group (1a), wherein R1, R2, R3, R4 are independently selected from C1-C30 alkyl, C2-C30 alkenyl, C2-C3 alkinyl, C3-C30 cycloalkyl, C6-C30 aryl, C2-C30 heteroaryl, C7-C30 arylalkyl, C3-C30 heteroarylalkyl, the wave line represents a covalent bond to the imine nitrogen atom, G is in each group (1a) independently selected from a quarternary carbon atom and from a cyclopropenylidene structural moiety, x is an integer equal one or higher, preferably equal two or higher, and the lone electron pair of the imine nitrogen atom and/or the pi-electrons of the imine double bond of at least one group B is conjugated with the conjugated system of delocalized electrons comprised in the structural moiety A, with the proviso that two or more of the substituents R1, R2, R3, R4 may be connected to form a ring that may contain also unsaturation and, if any of the substituents R1, R2, R3, R4 comprises two or more carbon ato…
