“…90 Interestingly, 4,5dibromophthalonitrile did not yield any traces of double-decker complexes under the conditions of template synthesis. 91 2.1.7 Sandwich phthalocyaninates with substituents in nonperipheral positions. All the aforementioned sandwiches contained substituents in the peripheral positions of the Pc rings, while nonperipherally-substituted complexes still remain relatively unexplored, although sterical hindrance caused by proximate nonperipheral substituents can have a profound influence on the structure and properties of such complexes, including particularly strong basicity of meso-nitrogen atoms and near-IR absorbance.…”

Synthesis and Spectroscopic and Luminescent Properties of Er, Yb and Lu Complexes with Cyano-Substituted Phthalocyanine Ligands

“…Metal phthalocyaninates are characterized by intense light absorption in the visible region [1][2][3][4], which determines their use as dyes [5][6][7] and elements of optical devices [8,9], while lanthanide complexes, along with the above properties, also exhibit absorption and, accordingly, emission in the near-IR region [10,11]. This opens up prospects for the use of such compounds as optical limiting devices [12][13][14], luminescent films, and sensors [9]. This fact is associated with the presence in the structure of the complex of an atom of a rare earth element, which makes it possible to realize luminescence of the 4f-type [15][16][17].…”

Supramolecular Organization and Optical Properties of Langmuir-Schaefer Films of 2,3,9,10,16,17,23,24-Octa-(3-(Methylthio)Phenyl)Phthalocyaninate Lutetium Acetate

“…Данные вещества находят применение в фотовольтаике [1][2][3], катализаторах [4][5][6], сенсорах [7][8][9] и оптических фильтрах [10][11][12]. Монофталоцианиновые комплексы лантаноидов, благодаря наличию аксиальных лигандов, обладают высокой активностью в химических реакциях [13][14][15][16][17] и широко применяются в нелинейной оптике [18][19][20]. Активно развиваются методы получения тонких пленок фталоцианинов для нелинейной оптики и не только [21][22][23].…”
