“…The OL effect of the three ferrocenyl substituted calixarenes 311−313 877 10 −16 cm 2 /W) was found for 313. The authors ascribed the OL effect on ns laser pulses as being mainly due to thermal nonlinearity and RSA, whereas the OL effect of fs laser pulses was due mainly to intrinsic electronic nonlinearity contribution.…”

“…The OL effect of the three ferrocenyl substituted calixarenes 311 – 313 (Chart ) was studied with ns pulses at 532 nm, with the OPL performance decreasing with the order 313 > 311 > 312 . On the other hand, when fs laser pulses at 800 nm were used, the nonlinearity was in the order 313 > 312 > 311 , and the largest value of nonlinear refraction index (η 2 = 9.5 × 10 –16 cm 2 /W) was found for 313 .…”

The control of luminous radiation has extremely important implications for modern and future technologies as well as in medicine. In this Review, we detail chemical structures and their relevant photophysical features for various groups of materials, including organic dyes such as metalloporphyrins and metallophthalocyanines (and derivatives), other common organic materials, mixed metal complexes and clusters, fullerenes, dendrimeric nanocomposites, polymeric materials (organic and/or inorganic), inorganic semiconductors, and other nanoscopic materials, utilized or potentially useful for the realization of devices able to filter in a smart way an external radiation. The concept of smart is referred to the characteristic of those materials that are capable to filter the radiation in a dynamic way without the need of an ancillary system for the activation of the required transmission change. In particular, this Review gives emphasis to the nonlinear optical properties of photoactive materials for the function of optical power limiting. All known mechanisms of optical limiting have been analyzed and discussed for the different types of materials.

“…Optical limiting. In the past two decades, much importance has been given to materials with strong optical limiting characteristics to guard optical instruments, particularly the human eye, from powerful laser beams (Suresh & Arivuoli, 2012;Patil et al, 2015;Singh et al, 2014;Å strand et al, 2000). Optical limiting refers to a high transmittance for low level inputs and decay of transmittance at intermediate levels of input as the intensity of the incident light rises (Krishnakumar & Nagalakshmi, 2008).…”

“…Second-and third-order nonlinear optical (NLO) materials have a wide range of practical applications (Suresh & Arivuoli, 2012), such as optical limiting (Patil et al, 2015;Singh et al, 2014), optical data storage (Å strand et al, 2000), terahertz wave generation (Krishnakumar & Nagalakshmi, 2008) and two-photon excited fluorescence microscopy (Ftouni et al, 2013). In such applications, organic NLO materials are more promising than inorganic materials (Boyd, 2003;Bosshard et al, 2001).…”

Crystal growth and characterization of second-and third-order nonlinear optical chalcone derivative: (2E)-3-(5-bromo-2-thienyl)-1-(4-nitrophenyl)prop-2-en-1-one Experimental and computational studies of linear and nonlinear optical (NLO) properties of (2E)-3-(5-bromo-2-thienyl)-1-(4-nitrophenyl)prop-2-en-1-one (5B2SNC) single crystals are reported. Good-quality and large-sized single crystals of 5B2SNC were successfully grown and characterized by powder X-ray diffraction and high-resolution X-ray diffractometry techniques. 5B2SNC was found to crystallize in the monoclinic noncentrosymmetric space group Cc and possesses moderately good crystalline perfection. The linear optical properties were investigated using the absorption spectrum, which reveals a direct optical band gap of 3.1 eV. The thermal stability was studied with thermogravimetric analysis/differential thermal analysis. The powder second harmonic generation efficiency was evaluated by the Kurtz and Perry method, and 5B2SNC was found to be 26 times more efficient than urea standard. Third-order NLO properties were studied by the z-scan technique with a femtosecond laser. The second hyperpolarizability was obtained to be $1.45 Â 10 À31 e.s.u. The molecule reveals a strong reverse saturation absorption and negative nonlinear refraction. The molecule exhibited good optical limiting properties, and its limiting threshold was measured to be $3.2 mJ cm À2 . In addition, static electric dipole moments, linear polarizabilities, and first-and second-order hyperpolarizabilities were calculated by density functional theory (DFT). Highest occupied molecular orbital/lowest unoccupied molecular orbital band gaps were also evaluated by DFT calculations. The experimental and theoretical results showed that 5B2SNC exhibits excellent second-and third-order nonlinear optical properties.

The cyclotriphosphazenes, which constitute an important class of inorganic compounds, can show new properties in the medical or technological fields depending on the properties of the substituted organic/inorganic groups. Herein, we aimed to determine electrical and theoretical properties of the nanographene-doped chalcone derivatives of dioxybiphenyl-bridged dispiro-cyclotriphosphazenes. For this aim, a new series of chalcone substituted spiro-cyclotriphosphazenes (3 a-g) have been synthesized by the reaction of dioxybiphenyl-bridged dispiro-cyclotriphosphazene (3) with chalcone derivatives (1 ag), respectively. Then, nanographene was doped to these spirocyclotriphosphazene 3 a-g using a hydrothermal system. The dielectric constant and loss factor of 4 % graphene-doped chalcone-substituted spiro-cyclotriphosphazene 3 g were determined as 167 and 2147 at 1 kHz, respectively, showing a significant increase compared to compound 3 g. The energy values of HOMO and LUMO orbitals are computed using DFT theory's level of B3LYP/6-31G(d,p). The FMO's energy gap values for 3 a-g were found to be 7. 92, 3.48, 3.26, 3.33, 3.53, 4.03 and 3.75 eV, respectively. Especially at frequencies below 10 kHz, the most striking result was observed for the nanographenedoped 3 d. While the AC conductivity of 3 d at 1 kHz was 3.87 × 10 À 9 S cm À 1 , the conductivity of the graphene-doped 3 d was calculated as 5.00 × 10 À 6 S cm À 1 . In addition, DC conductivity measurements were completed as a function of temperature and linearly increasing graphs were obtained with temperature. The activation energies calculated from the slopes of these graphs were 0.293, 0.305, 0.364 and 0.920 eV for 3 c, 3 d, 3 e and 3 g, respectively.
