title: Optical-limiting and photophysical properties of two soluble chloroindium phthalocyanines with alpha- and beta-alkoxyl substituents.
abstract: Two soluble heavy-metal phthalocyanine derivatives, namely, tetra-alpha-(2-ethylbutoxy) chloroindium phthalocyanine (alpha-InPcCl) and tetra-beta-(2-ethylbutoxy) chloroindium phthalocyanine (beta-InPcCl), were synthesized. Their optical-limiting properties in THF solution were investigated with a 532 nm nanosecond laser. The differences in the optical-limiting properties are attributed to their different photophysical properties. alpha-InPcCl is superior to beta-InPcCl as optical-limiting material, alpha substitution could be a useful factor to be considered in designing optical limiting materials based on metal phthalocyanines.
