Nonconjugated red-emitting dendrimers with p-type and/or n-type peripheries.

[reaction: see text] Dendron-encapsulated materials having a benzo[c][1,2,5]thiadiazole-based red-emitting core and p-type and/or n-type peripheries were synthesized. Intra- and intermolecular energy transfer from the peripheries to the core were found to be peripheries dependent. Red-emitting electroluminescent devices with promising performance were fabricated.
