    • Abstract


      In this paper, the non-linear optical properties of representative core-modified expanded porphyrins have been investigated with an emphasis on the structure-property relationship between the aromaticity and conformational behaviour. It has been shown that the measured two-photon absorption cross section ($\sigma^2$) values depend on the structure of macrocycle, its aromaticity and the number of 𝜋-electrons in conjugation.
