a Iterative exponential growth of BA-sequenced oligomer. b Iterative exponential and sequential growth of BA″B-sequenced oligomer. (i) Hydrolysis reaction (THF/NaOH aqueous solution); (ii) bromination reaction (NBS); (iii) Suzuki coupling reaction (Pd(OAc)2, RuPhos, and anhydrous THF, 70 °C). c GPC traces of BA-, (BA)2-, (BA)4-, and (BA)8-sequenced oligomers. d GPC traces of BA″B-, (BA″B)3-and (BA″B)7-sequenced oligomers. e MALDI-TOF overlapped spectra of (BA)8-sequenced oligomer and (BA″B)7-sequenced oligomer.
