Phthalocyanine photosensitizers with bathochromic shift, of suitable brightness, capable of producing singlet oxygen with effective efficiency

Films of substituted zinc phthalocyanines as active layers of chemiresistive sensors for ammonia detection

“…Metal phthalocyanines (MPcs) are highly conjugated cyclic molecules that consist of four isoindole units linked by nitrogen atoms to a central metal. Since the discovery of phthalocyanines as dyes in 1907, 1 their popularity has increased due to their semiconducting, optical and electrochemical properties, thermal stability and chemical inertness, as well as non-toxicity, which led to their use in medicine, 2–4 photocatalysis, 5–7 catalysis, 8,9 in solar cells, 10,11 and other fields. Another important area of application of phthalocyanines is chemical sensing.…”
