The controlled synthesis of oligoaromatics can provide materials wide utility. Here, we describe the preparation higher order oligoheterocycles via a tandem Suzuki cross-coupling protocol. This method has allowed for iterative construction fluorescent [Formula: see text],[Formula: text]-linked penta- and septaheterocyclic systems with modification terminal moiety allowing fine-tuning emission features.
