Self-assembled phthalocyanines (Pcs) monolayers have been studied with scanning tunnelling microscopy (STM) due to the organized 2D arrays that they form with potential applications in functional organic devices. The metal central region gives them important electronic, optical and optoelectronic properties and the possibility to extend the 2D monolayer into three dimensions through vertical reaction chemistry [1,2]. Synthetized metal Pcs [3,4] were assembled in graphite and followed by STM. High resolution images were obtained during the formation of the monolayer using a method previously applied in porphyrin monolayers [1,2,5,6]. The molecules were added to graphite trough an interface with tetradecane and the monolayer formation was followed in real time using molecular resolution images obtained by STM. Differential functional theory simulations were made to support the STM results.
