WebGeneral description. PTAA, poly (triaryl amine), semiconductor is an organic p-type semiconductor with hole mobilities of 10 −3 up to 10 −2 cm 2 V −1 s −1 which results in a high carrier mobility. It is a stable glassy polymer and has good ionization potential for … WebThen the clear solution was diluted with THF, passed through a 0.45 μm Teflon® filter, and precipitated by addition to stirring DI water. The polymer was filtered and dried under vacuum at 100 °C for 24 h. The yields of the final purified polymer products were all more than 95% by weight. Synthesis of potassium phenolate precursor
