Physical Properties of Phthalocyanine-based Materials

Nonlinear optical response of tetra and mono substituted zinc phthalocyanine complexes

“…The values obtained for I ୫ [χ (3) ] and ϒ are required to be large. The values in Table 3 are comparable to those previously reported values for monomeric Pc complexes [34,52,53]. (3) ] and ϒ values were larger for α substituted 1b and 3b in group (a), the same applies to group (b) where α substituted 5 gave larger values than β substituted 4.…”

The optical limiting of blue and green ytterbium double-decker phthalocyanines in solution and in poly(acrylic acid) as thin films

“…e 0 is the permittivity of free space and k is the wavelength of the laser light.At a molecular level, there is a direct correlation of Im[v(3) ] (in esu) with the hyperpolarizability (which provides the nonlinear absorption per mole of the sample) via the relationship shown in Eq. (5)[23,34,35]:…”

Enhanced optical limiting behaviour of indium phthalocyanine derivatives when in solution or embedded in poly(acrylic acid) or poly(methyl methacrylate) polymers

“…The second order hyperpolarizability (g) values of the materials were calculated using Eq. (8) [9,35].…”
