  • Electronic device and compound
    Patent number: 10403824
    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 th
