“…This study shows a new pathway in the development of advanced optoelectronic devices involving organic conjugated chromophores. Ren et al 55 and Sabbaghan et al 56 have investigated NLO domains engaging tin porphyrins and methoxycarbonylphenyl porphyrins, respectively. Also, Shehzad et al assessed third-order NLO and second hyperpolarizability of porphyrin–polyimide compounds.…”

“…Materials with large organic ring structures of conjugated π-electrons [1,2], such as porphyrins and their derivatives, are of great interest and got fast advanced for photonic applications like optical limiters [3][4][5], chemical sensors [6,7], molecular switches [8][9][10], and for medical applications like photomedicine [11][12][13], therapy [12,14] and diagnostics and others [11,15,16]. Until now, many works reported excellent features of porphyrins, for instance, broad visible absorption region [17,18], strong transition dipole moments [19], and high triplet state quantum yield [20].…”

Applying picosecond pulse trains propagating in meso-tetra(sulphonatophenyl) porphyrins and their Fe 3+, Mn 3+, Zn 2+ complexes, we studied the nonlinear dynamics at different pH values. The pulse train at wavelength 532nm is comprised of 20 subpulses with 70ps width and 13ns spacing. We simplified the energy structures of porphyrins and metalloporphyrins to five-level models. In solving coupled rate equations and two-dimensional paraxial field, we used Crank-Nicholson numerical method to do the calculations. The results revealed that in irregular metalloporphyrins with central paramagnetic ion Mn 3+ or Fe 3+, the central ion would act as electron acceptor, which leads to charge transfer of unpaired metal electron to the porphyrin ring π conjugated system, and strengthen the spin–orbit coupling of electronic systems and weaken the transition prohibition between electronic states in porphyrins. However regular metalloporphyrins with central diamagnetic ion Zn 2+ has similar optical properties to free base porphyrins, and Zn 2+ TPPS 4 has much longer excited state lifetimes and slower intersystem crossing. In solutions, hydrogen bond would be formed to porphyrin, which can change the transitions of π electrons and thus the charge transfer can be strengthened in the porphyrin ring. In weak intensity region with linear absorption, nonprotonated porphyrins with high pH value show better optical limiting (OL) effect. Conversely in high intensity region, protonated porphyrins with low pH value show better OL effect. Besides, increasing interaction distances of porphyrins and metalloporphyrins with laser pulses is another important factor to raise the OL effects.

The delocalization and rearrangement of π electron clouds in space is the crucial source of regulating nonlinear optical (NLO) performance. Herein, a core‐shell metal organic framework (MOF)‐heterojunction is constructed to achieve the effect of tuning NLO properties by promoting charge transfer through multiple interactions between heterogeneous interfaces. [Cd(L)(4,4′‐bpy)(H2O)]n (Cd‐MOF) is selected to coat on polyaniline (PANI) surface to form PANI@Cd‐MOF. The constructed heterojunction displays an enhanced reverse saturation absorption (RSA) signal compared with Cd‐MOF, and it should be noted that the third‐order NLO refractive behavior changes from the self‐defocusing of Cd‐MOF to the self‐focusing of PANI@Cd‐MOF. It is proposed that high‐speed electronic communication bridges established via the rich hydrogen bond network (O… H‐N) and π–π interactions between heterogeneous interfaces can effectively modify the π electron cloud density that finally regulates the NLO properties. This work is believed to provide new avenues and insights for the design of third‐order NLO materials.
