Beschreibung

Allgemeine Beschreibung

6-Cyano-2-naphthol (6CN2) is an aromatic alcohol that can be synthesized from 6-bromo-2-naphthol. It is a superphotoacid with the ground state pK_a^* value of 8.4 and excited state pKavalue of 0.2, respectively. 6CN2 protonates PANI-ES (polyaniline emeraldine salt) to form PANI-EB (emeraldine base), which shows enhanced conductivity. The proton-transfer kinetics and photophysical behavior of 6CN2 have been investigated.
