Abstract Synthesis and characterization of dendrimers containing thienylbenzene repeating units, red-emitting benzothiadiazole core, and triarylamine peripheries that bear naphthyl units are reported. The relevant dendrimers of different generations are classified as G nb (n= 1–3), while the tert-butyl dendrimers G na with the acceptor alone were also synthesized to serve as control chromophores that avoid donor–acceptor interactions. The resulting ...
