    • A compound according to a formula I and devices incorporating the same are described. The compound according to the formula I can have the structure: wherein X is Si or Ge; R1 and R2 represent mono, di, tri, tetra, or penta substitutions or no substitution; R3, R4 represent mono, di, tri, or tetra substitutions or no substitution; R1 and R2 are optionally joined to form a ring, which may be further substituted; L is a single bond or comprises an aryl or heteroaryl group having from 5-20 carbon atoms, which is optionally further substituted; and A is an aromatic group. A contains a group selected from the group consisting of indole, carbazole, benzofuran, dibenzofuran, benzothiophene, dibenzothiophene, benzoselenophene, dibenzoselenophene, triphenylene, azacarbazole, azadibenzofuran, azadibenzothiophene, azadibenzoselenophene, azatriphenylene, and combinations thereof, which are optionally further substituted. The device can include the compound according to Formula I in an organic layer.
