“…Also, as the colour of the emitted light is defined by the band gap of the π-π* electronic transition, any structural change will have an effect on the emitted region of the spectra 8 (Figure 2). In this context, attempts to control the energy gap and, therefore the properties of conjugated polymers, rely mainly on doping the material and also on refining its chemical structure 12,81,[83][84][85] . Conjugated polymers have emerged as excellent materials for making fluorescent nanoparticles [86][87][88] and they can exhibit high quantum yields depending on their chemical structure and degree of polymerisation 89,90 .…”
