Influence of blue valence absorption band on nonlinear absorption in dysprosium bisphthalocyanine studied by open aperture z-scan

Synthesis and third-order nonlinear optical properties of a sandwich-type mixed (phthalocyaninato)(schiff-base) triple-decker complexes

“…It is well established that the NLO response of phthalocyanine molecules is originated from a lot of structure factors [3]. And it has been suggested that sandwich-type lanthanide phthalocyanine complexes show improved optical nonlinearities due to their expanded p-electron system and the presence of the heavy lanthanide central metal [17e19, 21,24,26,35,37,38]. Compared to sandwich tripledecker analogs with holmium atom, the erbium complexes exhibit superior NLO response, which indicates that the lanthanide ion plays a more important role in determining the optical nonlinearity of the sandwich type complexes.…”

Double-decker bis(tetradiazepinoporphyrazinato) rare earth complexes: crucial role of intramolecular hydrogen bonding

“…14 Jiang and coworkers developed a common theory that helps to understand the structure-property relationship for this class of molecules. [14][15][16][17] Consequently, double-decker Pc derivatives, which are being actively investigated as promising materials for sensing devices, optoelectronics and spintronics, [14][15][16][18][19][20][21][22][23][24][25][26][27][28][29] can serve as ideal model systems to study the character of interligand interactions. Recently, we reported the first examples of tetradiazepinoporphyrazine-based sandwich-type lanthanide complexes and assumed the presence of additional intramolecular interactions between the macrocycles.…”

Cerium bis(tetradiazepinoporphyrazinate): synthesis and peculiarities of spectral and electrochemical behavior

“…It is well documented that sandwich tetrapyrrole complexes of rare earth elements (REE) possess unique electronic, optical and magnetic properties associated with strong p-p interactions between the macrocycles and represent promising materials for advanced applications. [1][2][3][4][5][6][7][8][9][10][11][12] In these complexes all REE are usually trivalent except for cerium, which can vary its oxidation state from +3 to +4 depending on the ligand nature. [13][14][15][16] Owing to this feature, cerium tetrapyrrole sandwich compounds demonstrate intriguing spectral and electrochemical properties 15,[17][18][19] and have potential applications in the areas of molecular mechanics, multibit information storage and molecular-based pressure sensors.…”
