Synthesis and Optical Limiting Properties of Axially Bridged Phthalocyanines: [(tBu4PcGa)2O] and [(tBu4PcIn)2O]

Molecular organization in the thin films of gallium(III) phthalocyanine chloride and its μ-(oxo)dimer: Optical spectroscopy and XPS study

“…MPcs can be used as active layers in a variety of optoelectronic devices, e.g., in organic field effect transistors [1,2], organic solar cells [3,4] or organic light emitting diodes [3,5]. Among other properties, a strong nonlinear optical (NLO) response (e.g., high (3) values) is typical of highly delocalized aromatic 18 -electron system of MPcs [6].…”

“…For instance, (t-Bu 4 PcGa) 2 O, the oxo-bridged dimer of t-Bu 4 PcGaCl, has two times higher value of saturation energy density and exhibites more intense photoluminescence emission in the red spectral region in comparison with the monomeric counterpart [5,9]. A facile way for such dimerization is thermal annealing of the thin films in the presence of atmospheric moisture.…”

Synthesis and strong optical limiting response of graphite oxide covalently functionalized with gallium phthalocyanine

“…A high architectural flexibility in a Pc structure facilitates the tailoring of their physical, optoelectronic and chemical parameters in a very broad range [1][2][3][4][5][6]. The exploitation of the chemical reactivity of the Ga-Cl bond in the R x PcGaCl (R: peripheral substituents in the Pc macrocycle) can allow the preparation of a series of highly soluble axially substituted and bridged Pc complexes [7][8][9][10][11][12][13][14]. Axial substituents in Pcs influence favorably nonlinear optical (NLO) absorption for the presence of a dipole moment perpendicular to the macrocycle in the axially substituted phthalocyanines [15][16][17][18][19][20][21].…”

Strong nonlinear optical refractive effect of self-assembled multilayer films containing tetrasulfonated iron phthalocyanine

“…Phthalocyanines with two-dimensional 18 p-electron system have been intensively investigated as nonlinear optical (NLO) materials [1][2][3]. Their chemical variations through introduction of functional central atom and peripheral substituents can alter the electronic structure of the phthalocyanine (Pc) macrocycles, therefore, they allow the fine-tuning of the optical nonlinear response.…”
