Article Abstract
The pressing demand for both established and innovative technologies to expand laser wavelengths has rendered high-performance nonlinear optical (NLO) crystals with large optical anisotropy indispensable. Here, centrosymmetric [SHC(NH)]CdBr (1) and pseudo-2D layered [SC(NH)]CdBr (2), as well as pseudo-3D noncentrosymmetric [SC(NH)]CdCl (3) are successfully synthesized through the introduction of π-conjugated SC(NH) groups. Compared to ionic compound 1 containing full-halogen coordination tetrahedra, covalent compounds 2 and 3 featuring novel polar [SC(NH)]CdX (X = Br, Cl) tetrahedral units demonstrate enhanced bandgaps (>4 eV) and birefringences (>0.3@546 nm) due to the unique coordination environment. Remarkably, 3 exhibits a strong second-harmonic generation (SHG) response (2.1 × KHPO(KDP)), high laser-induced damage thresholds (30 × AgGaS(AGS), and excellent water stability. The birefringence of 3 is the largest among the hybrid halides NLO crystals containing d metal cations. Detailed theoretical calculations confirm that such a modified double-site dual functional building units (FBUs) substitution is an effective strategy for designing superior optical materials with large birefringence and strong SHG response, paving the way for the development of high-performance devices in related fields.

Polar protic and aprotic solvents can effectively simulate the maturation of breast carcinoma cells. Herein, the influence of polar protic solvents (water and ethanol) and aprotic solvents (acetone and DMSO) on the properties of 3-(dimethylaminomethyl)-5-nitroindole (DAMNI) was investigated using density functional theory (DFT) computations. Thermodynamic parameters retrieved from the vibrational analysis indicated that the DAMNI's entropy, heat capacity, and enthalpy increased with rising temperature.

Photonic Reservoir Computing (RC) systems leverage the complex propagation and nonlinear interaction of optical waves to perform information processing tasks. These systems employ a combination of optical data encoding (in the field amplitude and/or phase), random scattering, and nonlinear detection to generate nonlinear features that can be processed via a linear readout layer. In this work, we propose a novel scattering-assisted photonic reservoir encoding scheme where the input phase is deliberately wrapped multiple times beyond the natural period of the optical waves [0,2π).

Understanding how molecular aggregation influences nonlinear optical properties is essential for advancing organic fluorophores in imaging, sensing, and photonic applications. However, the relationship between the molecular aggregation and the magnitude of nonlinear two-photon absorption cross-section remains underexplored. Here, we systematically investigate the aggregation-dependent two-photon absorption properties of the fluorophore TPAPhCN by tuning the degree of aggregation.

A series of unsymmetrically substituted BODIPY dyes featuring fused benzo- or naphtho-fragments on one pyrrolic unit were synthesized from the corresponding pyrrolic precursors. The synthetic route was optimized using a modular approach based on the condensation of formylpyrroles with alkylpyrroles, enabling the identification of precursor combinations that minimize byproduct formation and improve preparative yields. The resulting benzo- and naphtho-fused BODIPYs display intense fluorescence in the red region, with emission maxima spanning 590-680 nm and fluorescence quantum yields ranging from 0.

Incorporating atomically thin two-dimensional (2D) materials with optical fibers expands their potential for optoelectronic applications. Recent advancements in chemical vapor deposition have enabled the batch production of these hybrid fibers, paving the way for practical implementation. However, their functionality remains constrained by the integration of a single 2D material, restricting their versatile performance.
