“…Phthalocyanines (Pc) and their metal complexes (PcM) have been studied for many years in great detail, mostly for their wide varieties of high-technology applications, including their use in dyes and catalysts, [1,2] semiconducting materials, [3] nonlinear optical (NLO) devices, [4] liquid crystals, [5] Langmuir-Blodgett films, [6] electrochromic and electroluminescent displays, [7] photovoltaic cells, [8] photosensitizers, [9] gas sensors, [10] and other areas. [11,12] Recently, phthalocyaninato rare-earth complexes have received considerable attention because of their appealing semiconducting, electrochemical, and photophysical properties.…”
