“…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.

We report the synthesis and characterization of two new mesoferrocenylporphyrins, with the ferrocenyl unit attached at the para position of a C 6 F 4 group by a C-N bond with -NH(CH 2 ) 2 NH-(2a) and -NH(CH 2 ) 4 NH-(2b) spacers. Compounds 2a and 2b were characterized through elemental analyses, electrospray ionization high-resolution mass spectrometry, 1 H NMR, UV-visible and fluorescence spectroscopies, electrochemistry and spectroelectrochemistry. The free base porphyrin 2 was included for comparison purposes. The binding ability of 2 and the porphyrin derivatives 2a and 2b with calf thymus DNA was determined using UV-visible and fluorescence spectroscopies. The results suggest that the interaction of these systems most probably occurs through π-stacking by non-classical modes involving the partial insertion of the C 6 F 5 ring between adjacent base pairs on DNA and possible hydrogen interaction with the aliphatic -NH(CH 2 ) n NH-(n = 2 or 4) groups with calf thymus DNA. Moreover, we also demonstrate that porphyrins generate singlet oxygen species and show good photostability after irradiation.

Am etal-free, regioselective synthesis of trisubstituted pyrroles has been developed throughaformal [3+ +2] cycloaddition reactionb etween 2H-azirines and nitroalkenes under visible light/photoredox-catalyzedc onditions. The re-action proceeds through 2H-azaallenyl radical addition on bnitrostyrenes in aM ichael fashion followed by ab ase-mediated denitration reaction. The directive group influence of the nitro group controlst he regiochemistry of the reaction.
