Electronic Device

A reactive mesogenic compound corresponding to the formula:

• E1-D1-A1-Z1-A2-Z2-A3-D2-E2,
• in which formula:
• E1, E2 are end groups, of which E1 includes at least one reactive end group that is cross-linkable upon initiation;
• D1, D2 are spacer groups,
• A1, A2, A3 are optionally substituted conjugated units,
• Z1, Z2 are rigid spacer groups,
• wherein A2 is chosen from the group of oligothiophenyl groups.

An electronic device comprising a semiconductor element provided with an organic semiconductor material that comprises reactive mesogenic units that are present in a smectic or crystalline phase and are at least partially ordered in a monodomain structure, said mesogenic units corresponding to the formula:

• E1-D1-T-D2-E2,
• in which formula:
• E1, E2 are end groups of which at least El is cross-linkable upon initiation,
• D1, D2 are spacer groups,
• T is a core comprising one or more, optionally substituted conjugated units,
• wherein the material comprises a first and a second mesogenic unit that are mutually difference and, upon cross-linking, have the same smectic or crystalline phase.
