Melting behavior of poly(۳-hexylthiophene) nanofibers in solution

Poly(۳-hexylthiophene) (P۳HT), as a conjugated polymer, has attracted much attention in organicphotovoltaics and electronic applications of organic thin films. P۳HT crystallization being detrminanton the efficiency of equipments made of this polymer, has long been of interest to researchers. In thisstudy, melting behavior of P۳HT crystalline nanofibers in solution is studied by UV-vis spectroscopy.The free exciton bandwidth (W) as a curve fitting parameter and crystallinity (Xc) were calculatedthrough Frank-Condon analysis. Reduction of crystallinity (confirmed by decrease in Xc) andcrystalline quality (confirmed by increase in W) were investigated with temperature rising.
