Photostable naphthalocyanines (see Figure) can act as optical limiters, simultaneously absorbing nanosecond laser pulses at 532 nm and 1064 nm. In these naphthalocyanines, where M can correspond to Zn, InCl, or In( p ‐trifluoromethylphenyl), the pattern of substitution and the nature of the substituents were found to be critical factors in achieving such a combination of linear and nonlinear optical properties.
