“…Over the past thirty years, additional research has been conducted to find more affordable and effective materials for organic NLO materials, like Schiff bases, are a class of compounds that have drawn a lot of interest because of their straightforward design, synthetesis flexibility, and π-conjugated framework in the form of a D-π-A push-pull system. This makes them a promising class of NLO materials [34][35][36][37].…”

The synthesized Schiff base ligand (compound Z1) is analyzed by IR, mass, 1HNMR, and 13CNMR spectroscopies. Computational chemical modeling is performed to examine the geometry optimization and molecular structure of compound Z1 by using the DFT/ WB97XD/6-31+G(d,p) method. The parameters HOMO-LUMO energies with nonlinear optical (NLO) properties are computed. The results indicate good agreement cor-relations of experimental and theoretical data so that compound Z1 prove to have good NLO properties. The NLO properties of the compound Z1 are examined under excitation with a 473 nm, cw, low power laser beam via two techniques viz., diffraction patterns (DPs) and the standared Z-scan techniques. The nonlinear refractive index (NLRI), n2, of compound Z1 is estimated by the two techniques were as high as n2 value of 3.03×10-11 m2/W is obtained at the maximum power input due to the DPs. Both static and dynamic all –optical switching (SAOS and DPOS) are tested using 473 nm and 532 nm cw low power laser beams.

This research presents the optical limiting properties of a novel axially linked D‐A type compound, LaPc‐C60(OH)n, where lanthanide phthalocyanine serves as the donor and fullerenol as the acceptor. The incorporation of fullerenol expands the π‐conjugated system, decreases the aggregation of the phthalocyanine, and significantly increases the solubility of the compound. The establishment of this D‐A system promotes intramolecular electron transfer, effectively improving both the non‐linear optical (NLO) response and optical limiting properties. In addition, homogeneous poly(methyl methacrylate) (PMMA) composite films (LaPc‐C60(OH)n/PMMA) are prepared using a simple solution casting method. Compared to fullerenol or lanthanum phthalocyanine individually, LaPc‐C60(OH)n exhibited a superior NLO response both in solution and in the solid composite film. In particular, LaPc‐C60(OH)n/PMMA demonstrated an increase in the non‐linear absorption coefficient (2050 cm GW−1) and a larger third‐order magnetization (1.84 × 10−8 esu). In addition to exhibiting an excellent NLO response at 532 nm, LaPc‐C60(OH)n also shows significant NLO enhancement at 1064 nm, extending the limiting range into the near‐infrared region. This behavior is attributed to different nonlinear absorption mechanisms and the synergistic effect that arise from the photo‐induced electron transfer process between the fullerenol and LaPc.
