A new sulfobutylated phenol formaldehyde resin (BSPF) was prepared for the first time. Cyclic voltammetry and electron spin resonance were used to investigate oxidation process of BSPF, in which stable oxidation state with radical was formed. Inspired by electron transfer during oxidationof BSPF, water soluble PEDOT:BSPF was prepared using BSPF as semiconductive dopant. As hole transport material (HTM), PEDOT:BSPF was applied in polymer solar cells and showed higher power conversion efficiency than that in case of PEDOT:PSS. PEDOT:BSPF is a very promising HTM for organic electronic devices andBSPF shows great potential as dopant of polymericsemiconductors. A novel perspective for the design ofdopant of semiconductors and high value‐addedapplication of formaldehyde resin were discussed.
