“…9 Nevertheless, various syntheses of phthalocyanine derivatives have been developed during the past decades, which allow for the modulation of chemical as well as photophysical properties and have led to the wide application of phthalocyanines. These include the areas of catalysis, 10−12 materials science (e.g., solar cells, 13−16 gas sensors 17 ), opto-and thermoelectronic devices, 15 or medicinal applications 18 such as photodynamic therapy (PDT). 19−21 Furthermore, phthalocyanines show promising absorption properties in the near-infrared region of the solar spectrum and are known to be efficient triplet sensitizers for the production of singlet oxygen.…”

While photochemical transformations with sunlight almost exclusively utilize the UV–vis part of the solar spectrum, the majority of the photons emitted by the sun have frequencies in the near-infrared region. Phthalocyanines show high structural similarity to the naturally occurring light-harvesting porphyrins, chlorins, and mainly bacteriochlorins and are also known for being efficient and affordable near-infrared light absorbers as well as triplet sensitizers for the production of singlet oxygen. Although having been neglected for a long time in synthetic organic chemistry due to their low solubility and high tendency toward aggregation, their unique photophysical properties and chemical robustness make phthalocyanines attractive photocatalysts for the application in near-infrared-light-driven synthesis strategies. Herein, we report a cheap, simple, and efficient photocatalytic protocol, which is easily scalable under continuous-flow conditions. Various phthalocyanines were studied as near-infrared photosensitizers in oxidative cyanations of tertiary amines to generate α-aminonitriles, a synthetically versatile compound class.

“…[16][17][18][19] The unoccupied states, probed by IPES, show two distinct peaks within 1.5 eV (above E F ), namely c and d. Several theoretical works on the CoPc empty states are reported in the literature. 14,17,[20][21][22][23] However, most of the published calculations are performed on the isolated molecule approximation, even though solid aggregation induces changes in the electronic properties of the organic semiconductors. 24,25 The calculated CoPc electronic structure is very sensitive to the theoretical functional used to model the exchange-correlation interactions.…”

The optoelectronic and thermoelectric properties of 4-dimethylaminopyridine flexible compound are investigated by combining the full-potential linearized augmented-plane wave method and the Boltzmann transport theory. The flat bands are observed around the Fermi energy in the band structure which is implying that this organic polymer may be used in the superconductivity devices. It is found that this polymer has the birefringence property in the low energies. Obtained Plasmon energy can be compared to the available experimental and theoretical data for good optical materials. Thermoelectric figure of merit is predicted about 0.98 which result suggest a new application of this polymer in the thermoelectric devices.
