Electrical and electrochemical properties of double-decker Lu(III) and Eu(III) phthalocyanines with four imidazoles and N-alkylated imidazoles

Electrical and gas sensing properties of novel cobalt(II), copper(II), manganese(III) phthalocyanines carrying ethyl 7-oxy-4,8-dimethylcoumarin-3-propanoate moieties

“…All the films of the compounds showed nearly equal conductivity values at the same temperatures, from 293 K to 378 K. The T > 378 K film of compound 3 exhibited the highest conductivity compared to the others. Calculated DC conductivity values in this study were found to be in the same order of magnitude as the previously reported values for different phthalocyanine compounds [23,42]. The curves in Fig.…”

“…Similar behaviors have been reported previously for some organic molecules. This behavior was attributed to exhaustion of absorbed oxygen by the authors [42][43][44][45][46]. The second linear region in the Arrhenius plot shows that the compounds behave as intrinsic semiconductors.…”

Synthesis, Aggregation, Antioxidant and DNA‐Binding Properties of Metallophthalocyanines Bearing 5‐Tert‐butyl‐2‐hydroxyphenoxy Groups

“…Electrostatic and hydrogen binding modes are the fundamental binding forces in external binding mode . One of the important factors of the interaction mode of phthalocyanine compound to DNA is the degree of the wavelength shift and further hypochromism or hyperchromism ,…”

“…[39] One of the important factors of the interaction mode of phthalocyanine compound to DNA is the degree of the wavelength shift and further hypochromism or hyperchromism. [39,7] In this work, the absorption titration study of compound 6 with CT-DNA in the absence and presence of CT-DNA was conducted to investigate the binding mode of DNA with compound 6. The absorption titration of compound 6 was recorded between the range of 300 and 800 nm in the absence and presence of CT-DNA.…”

“…Phthalocyanine compounds have strong 18‐π electronic delocalization, thermal, photostability, photophysical, photochemical properties, and visible area optical properties. Their exceptionally properties have encouraged research in other areas, including catalyst, photo dynamic therapy (PDT), electrochromic displaying systems, solar cells, photovoltaic optics, liquid crystals, semiconductors, laser dyes,, chemical sensors, optical storage devices,, non‐linear optics,, dyes and pigments, gas sensors, antioxidant potential ,. It is well known that design of new phthalocyanines strongly affects their properties, applications and performance.…”
