“…As mentioned in the introductory section, these studies include porphyrin-and ferrocene-fullerene derivatives. 16,17,[22][23][24][25][26][27][28][29][30][31][32][33][34][87][88][89][90][91][92][93][94][95][96][97][98] Among others, previous works by our groups clearly showed a dramatic effect of the functionalization on the NLO response, 22,38,97 further proving the existence of the charge-transfer event. 99,100 For instance, when studying the NLO properties of two fullerene derivatives in various chemical environments under 35 ps, 532 nm using Z-scan technique, the presence of an electron donor moiety causes an enhancement of the NLO response by almost a factor of two, 38 with the porphyrin moieties displaying the highest response (see Table S3 in the ESI †).…”

By means of different spectroscopic techniques, we investigate a novel series of porphyrin derivatives (H2TPP), connected to dibenzo-24-crown-8 (DB24C8) moieties, which undergo self-assembly with different methano[60]fullerene units bearing dibenzylammonium (DBA) cations. The formation of both [2] and [3]pseudorotaxanes was proved by means of NMR, UV-Vis-NIR absorption and emission spectroscopies. With the support of molecular modelling studies, spectroscopic investigations showed the presence of a secondary interaction between the porphyrin and the C60 chromophores leading to the formation of different types of "face-to-face" assemblies. Remarkably, investigations of the non-linear optical response of these supramolecular systems showed that individual porphyrin and fullerene derivatives exhibit significantly lower second hyperpolarizability values when compared to their pseudorotaxanes functionalised counterparts. This proves that this class of supramolecular materials possesses relevant NLO response, which strongly depends on the structural arrangement of the chromophores in solution.

“…From Table 2, the TONLO susceptibility (χ 3 ) of basic violet 3 in 1propanol has higher than that of other solvents. The value of TONLO susceptibility of basic violet 3 dye in the present study was compared with some reported materials [24][25][26][27] and it is worth noting that, the obtained results are higher than that of reported materials.…”

The present work aims to study of third-order nonlinear optical (TONLO) behavior of basic violet 3 dye dissolved in polar protic and aprotic solvents, namely, ethanol, 1-propanol, acet0one and dimethyl sulfonate (DMSO), respectively. The polarity of the solvent used to have a substantial impact on the linear and TONLO properties of the dye sample. The dye exhibit self-defocusing nonlinearity due to thermally induced nonlinear refractive index and nonlinear absorption coefficient reveals the character of both saturable and reverse saturable absorption (RSA). The order of magnitude of nonlinear refractive index (n2) and nonlinear coefficient of absorption (β) of dye sample was determined to be 10 -7 cm 2 /W and 10 -3 cm/W, respectively. The real and imaginary factors of the TONLO susceptibility of basic violet 3 dye were measured to be the power of 10 -5 esu. The results are revealed that the possibility of utilizing the dye sample in various photonics and optoelectronics applications.

2, 3-butanedione dihydrazone (BDDH) synthesized via chemical route and nonlinear optical parameters, such as nonlinear refractive index (n2), nonlinear absorption coefficient (β), third-order nonlinear optical susceptibility (χ(3)), second hyperpolarizability (γ), and optical-limiting behavior were investigated by single beam z-scan technique for different concentrations. Synthesized sample were irradiated by a Q-switched, frequency doubled Nd:YAG laser and found that n2 and β increases linearly with increasing concentration and hence γ decreases linearly. The excited-state absorption cross sections of BDDH were found to be larger than ground-state absorption cross sections, and it leads to reverse saturable absorption (RSA). The experimental results are well in agreement with the theory and also establish BDDH as one of the potential candidate materials for optical limiting at 532 nm.
