Please Contact Us There are many derivatives of the parent phthalocyanine, where either carbon atoms of the macrocycle are exchanged for nitrogen atoms or the peripheral hydrogen atoms are substituted by functional groups like halogens, hydroxyl, amine, alkyl, aryl, thiol, alkoxy and nitrosyl groups. A soluble derivative of copper phthalocyanine, that is 2,9,16,23-tetra carboxyl copper phthalocyanine (CuTCPc), is synthesized in this paper. Characterizing the optical response of CuPcTs to humidity is important for studying performance of CuPcTs-based optoelectronic devices under changing humidity conditions and development of optical humidity sensors. Before initiating SPE measurements, the CuPcTs film was exposed to 3% RH for 3hours. At RH>60%, the formation of H2O layers containing mobile Na+ ions can increase the effective contact area at electrodes and result in improved electronic transport by allowing charge carriers to hop between hydrated ionic structures consisting of coordinated Na+ and dipolar H2O, leading to a decrease in R2.

While optical response of sulfonated phthalocyanines has been well-studied in solution, less information is available about water interaction with solid films15, 19. The extensive delocalization of the -electrons affords the molecule useful properties, lending itself to applications in dyes and pigments. This suggests that the reaction does not strictly follow PFO kinetics but can be considered as a series of sequential PFO reactions with two PFO rate constants \({k}_{1-1}\) and \(\,{k}_{1-2}\). Crowding of adsorbates near these groups facilitates salt dissociation leading to formation of 4 Na+ ions and negatively charged CuPc(SO3 This is consistent with saturation of a strongly hydrophilic adsorption site at low RH (corresponding to \(\,{k}_{1-1}\)) and an increase in the activity of a second site as RH increases (corresponding to \(\,{k}_{1-2}\)).
