Abstract
This short review gives a concise overview of the impact of deposition methods on the supramolecular arrangement of metallic phthalocyanine films and their applications. Primarily, an introduction about the possible phthalocyanine molecular structures and derivatives obtained from modification on the phthalocyanine rings was presented. The possibility of perfecting/improving the supramolecular arrangement of metallic phthalocyanine (MPcs) films by using different deposition techniques such as Langmuir-Blodgett (LB), Langmuir-Schaefer (LS), Layer-by-Layer (LbL), physical vapor deposition (PVD) and electrodeposition was discussed in further details. Herein, we highlighted some techniques used on the characterization of supramolecular arrangement (morphology, optical properties, and molecular organization), including the impact on sensing applications. The main scope of this short review is focused on the advances made in this research field in the last five years.
Highlights
Phthalocyanines (Pcs) are a class of compound that display many applications, mostly related to dyes and inks due to its intense color (Hakeim et al 2015)
The deposition methods applied to the formation of the MPc and MTsPc films can tune the supramolecular arrangement, which contributes to the development of technological devices
The MPc films presents molecular aggregates due to the tendency of phthalocyanines to aggregate themselves in solution, which can be transferred to the substrate surface during the film deposition (Martin et al 2018, Rubira et al 2017)
Summary
Phthalocyanines (Pcs) are a class of compound that display many applications, mostly related to dyes and inks due to its intense color (Hakeim et al 2015). The properties are directly related to the supramolecular arrangement, which can be tuned by the deposition technique (Martin et al 2018, Volpati et al 2008), MPc molecule used (Del Caño et al 2005, Usol’tseva et al 2014) as well as thermal treatment (Roy et al 2014).
