“…Beyond their absorption features, many other recognized properties arose from the preparation of Pcs, allowing these macrocycles to be considered leading chemical entities, applied in several technologies over the years, including as catalysts [7][8][9][10], sensors [11][12][13], thin films [14][15][16][17], liquid crystals [18][19][20], semi-conductors [21][22][23], textile dyes [24,25], light-harvesting dyes in solar cells/organic photovoltaics [26][27][28][29], absorbers in nonlinear optics [30][31][32][33][34][35][36], photocatalysts [37,38], photosensitizers in phototherapies [39,40], photosensitizers photodynamic inactivation of bacteria [41,42], and as contrast agents in medical imaging [43][44][45][46]. Of the many applications found for phthalocyanines over the many decades after their discovery [47][48][49], recent years witnessed a solid growth in applications for phthalocyanines, particularly those relying on their excelling photophysical propert...…”
