a Preparation of regio- and sequence-controlled conjugated topological polymers from discrete oligomers. b UV–Vis spectra of the polymers poly(BAB) (green line), poly(BA′B) (yellow line), and poly(BA″B) (orange line) dissolved in the THF. c Fluorescence-emission spectra of the polymers poly(BAB) (green line), poly(BA′B) (yellow line), and poly(BA″B) (orange line) dissolved in the THF. The fluorescence-emission photograph inserted in Fig. 6c was taken under 365-nm ultraviolet light.
