10.1002/cphc.200500595.abs Two soluble heavy‐metal phthalocyanine derivatives, namely, tetra‐α‐(2‐ethylbutoxy) chloroindium phthalocyanine (α‐InPcCl) and tetra‐β‐(2‐ethylbutoxy) chloroindium phthalocyanine (β‐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. α‐InPcCl is superior to β‐InPcCl as optical‐limiting material, α substitution could be a useful factor to be considered in designing optical limiting materials based on metal phthalocyanines.
