P3HT and P3HOT homopolymers do not have quinoidal character on ground state and the frontier molecular orbitals of its copolymers are delocalized throughout the main chain (see Fig.
Under the conditions described above the quinoidal forms for para- and ortho-species can be assigned by characteristic chemical shifts in [sup.
At pH 1-3 the flavylium cation is red colored; at pH 5 the colorless carbinol pseudo base is generated; at pH 7-8 the blue purple quinoidal base is formed.
Furthermore, model compound studies show that, when QDI reacts with carbon free radicals, attachment can occur on the alkyl nitrogen atom and on the quinoidal ring as well.
2] and quinoidal products and both chemical species may participate in electrophilic conjugation reactions with cysteine residues of the Nrf2-Keap1 complex, allowing the translocation of Nrf2 and thus starting the pathway [6-8].
The reaction of dehydro-chlorination could occur in the irradiation of electron beam to PVC, but obtained HCI failed to protonate the quinoidal sites of PANI effectively because of the asynchronous process of film formation and PVC dehydro-chlorination.
