“…Aware of the importance of phthalocyanine-related molecules, such as subphthalocyanines, naphthalocyanines, porphyrazines, and porphyrinoids, the recent discoveries (in the last five years) will solely consider the application of phthalocyanines in photonic-based materials technologies. Indeed, there are several highly cited review records in several sub-fields, e.g., photomedicine [ 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 ], photovoltaics [ 61 , 62 , 63 ], nonlinear optics [ 64 , 65 , 66 ], photocatalysis [ 67 , 68 , 69 ], among other photo-applications [ 70 , 71 , 72 ], portraying phthalocyanines among the therein discussed materials/molecules. Herein, more than a comprehensive view on the recent discoveries, a critical review of the most acclaimed/considered reports (i.e., most cited) was the driving force in this work, aiming to provide a brief and direct insight on the latest milestones in phthalocyanine science.…”

Phthalocyanines have enjoyed throughout the years the benefits of being exquisite compounds with many favorable properties arising from the straightforward and diverse possibilities of their structural modulation. Last decades appreciated a steady growth in applications for phthalocyanines, particularly those dependent on their great photophysical properties, now used in several cutting-edge technologies, particularly in photonic applications. Judging by the vivid reports currently provided by many researchers around the world, the spotlight remains assured. This review deals with the use of phthalocyanine molecules in innovative materials in photo-applications. Beyond a comprehensive view on the recent discoveries, a critical review of the most acclaimed/considered reports is the driving force, providing a brief and direct insight on the latest milestones in phthalocyanine photonic-based science.

“…[ 2 ] Phthalocyanines constitute a very rich family of compounds enabling coordination with more than 70 elements of the periodic table in their central coordination site alongside with numerous possible substituents at the periphery. Possessing an 18 π‐electron conjugation system in their neutral redox state, phthalocyanines demonstrate remarkable optical properties which are extensively studied for potential applications in organic and hybrid photovoltaics (PV), optical memory devices, [ 3 ] photodynamic therapy (PDT), and fluorescence diagnostics of cancer, [ 4 ] optical gas sensors, [ 5,6 ] and field‐effect transistors, [ 7,8 ] photocatalysis, [ 9,10 ] and light‐harvesting elements in artificial photosynthetic systems. [ 11,12 ] At the same time, radical forms of phthalocyanines are of great interest for organic magnetism and molecular spintronics.…”

Plasmonic enhancement of absorption in charge‐transfer (CT) complexes formed under NO2 gas adsorption onto 2D hybrid structure, based on the metal–organic monolayer and gold nanoparticles (AuNPs), is demonstrated. By using Langmuir–Blodgett deposition of low‐symmetry zinc phthalocyanine (ZnPc) molecules, the metal–organic monolayer is fabricated with greatly suppressed intermolecular aggregation. Oxidation of the monolayer through coordination of NO2 molecules with axial zinc ions of ZnPc molecules gives rise to the specific absorption band inherited to cation radical ZnPc+. The hybrid AuNPs–ZnPc structure is engineered to maximize exciton–plasmon interaction of CT complexes at the radical form of the metal–organic monolayer. Excellent spectral and spatial overlaps with plasmon resonance boost absorption of CT internal optical transition, so‐called “fingerprint” band, by a factor of six from 0.45% to 2.8% in total. The approach paves the way for efficient plasmonic control over photochemical reactions promoted by charge‐transfer complexes in metal–organic films. In particular, the plasmonic effect is harnessed to improve NO2 gas sensing properties; the experimental study shows a 15‐fold increase of the detection efficiency in the specific band of CT complexes under the gas exposure.

“…[8][9][10] Among them, nickel phthalocyanine (NiPc) is considered as a promising catalyst for CO 2 RR due to its proper active site. [11][12][13][14][15][16] Unfortunately, the pristine NiPc is subjected to inferior activity and stability owing to the poor CO 2 adsorption and activation rooted in the electron-de cient Ni site. [17][18][19][20][21] The electronic localization of active site with an increased electronic density is able to optimize the CO 2 adsorption/activation in traditional inorganic catalysts.…”

Designing efficient catalysts with high activity and selectivity is desirable and challenging for CO2 reduction reaction (CO2RR). Nickel phthalocyanine (NiPc) is a promising molecule catalyst for CO2RR. However, the pristine NiPc suffers from poor CO2 adsorption and activation due to its electron deficiency of Ni–N4 site, which leads to inferior activity and stability during CO2RR. Here, we develop a substituent-induced electronic localization strategy to improve CO2 adsorption and activation, and thus catalytic performance. Theoretic calculations and experimental results indicate that the electronic localization on the Ni site induced by electron-donating substituents (hydroxyl or amino) of NiPc greatly enhances the CO2 adsorption and activation, which is positively associated with the electron-donating abilities of substituents. Employing the optimal catalyst of amino-substituted NiPc to catalyze CO2 into CO in flow cell can achieve an ultrahigh activity and selectivity of 99.8% at the current densities up to 400 mA cm-2. This work offers a novel strategy to regulate the electronic structure of the active site by introducing substituents for highly efficient CO2RR.
