“…Organic nonlinear optical (NLO) materials with high nonlinearities have been widely used in biological probes, laser dyes, various therapies, and sensing. − The high nonlinearities are the result of optimum combinations of various characteristics, such as the molecular conformation, conjugation length, and transport properties; , hence, further explorations of NLO enhancement principles are of great interest. A π-conjugated system and an electron donor–acceptor structure are important mechanisms for generating organic materials with optical nonlinearity, and pyrenyl and pyrene-based derivatives are representative examples of π-conjugated systems. − …”

The nonlinear absorption properties and excited-state dynamics of two linear D−π–A pyrene derivatives (B1 and B2) with different push–pull properties were investigated and compared. The transient absorption spectra provide information about their excited states, revealing a transition from the local excited (LE) state to the charge transfer (CT) state in each of the compounds. The Z-scan measurements show that both derivatives exhibit reverse saturable absorption at multiple excitation widths (fs, ps, and ns). Combined with quantum chemical calculations, the experimental results indicate that B1 (with pyrene as the donor) shows superior two-photon absorption (TPA) at shorter wavelengths (≤650 nm) because of more π–π* transition and that the stronger CT to the pyrene group contributes to the resonance enhancement of the TPA of B2 (with pyrene as the acceptor) at near-infrared wavelengths. In addition, both compounds exhibit satisfactory optical limiting performance, while the thresholds of B2 are 0.0029–0.01 and 0.092 J/cm2 under excitation by femtosecond (532–900 nm) and picosecond (532 nm) pulses, respectively.

“…In this scenario, specific interactions with the solvent cage or charged or polar groups can exhibit the optical behaviors (NLO) of a molecular complex. The Proton transfer complexes having high molecular polarizabilities, because of their π‐delocalized electronic systems, which show improved nonlinearities, hyperpolarizabilities, and suitable physicochemical behaviors [14] …”

A Proton‐Transfer Complex Containing 5‐Hydroxy‐isophthalic Acid with 3,3′‐(Piperazine‐1,4‐diylbis (methylene)) Dibenzonitrile: Structural Topology, Hirshfeld Analysis, NLO, and DFT Studies

This work focuses on the study of a proton‐transfer complex (1) of 5‐hydroxy‐isophthalic acid (HIPA) and 3,3′‐(piperazine‐1,4‐diylbis(methylene)) dibenzonitrile (PBN). The single‐crystal XRD reveals that the HIPA and PBN molecules in complex (1) are mutually connected through intricate N+−H−O− H‐bonding interactions. Herein, close and open aperture measurement for the third‐order nonlinear optical response of the complex (1) has been investigated using the Z‐scan technique which shows its potential application in optoelectronic and photonic devices. Further, DFT calculations have been done for the HOMO‐LUMO energy gap and Mulliken atomic charge analysis which helps us to understand the proton‐transfer mechanism in the complex (1). The topological and Hirshfeld surface analysis were also achieved to understand the importance of non‐covalent interactions in the stability of the supramolecular structure and NLO properties.
