Summary: Pyrazine-decorated benzotriazole cores allow the orthogonal combination of two dipolar systems within a single molecule. The photophysical features of these derivatives showed remarkable differences depending on the substitution in the pyrazine ring of the benzotriazole core. Furthermore, these compounds exhibited good two-photon absorption properties, and TD-DFT calculations supported the experimental observations.

Summary: Novel water-soluble asymmetric porphyrins containing three sulfo-phenyl fragments and small heterocyclic residues (benzothiazole, benzoxazole, and benzo-N-methylimidazole) were synthesized using metal-complex catalysis. The porphyrins exhibited different behaviors in water, with protonation and self-association processes observed for benzothiazole and benzoxazole residues, and protonation processes dominating for benzo-N-methylimidazole residue. The formation of associates in the porphyrins was found to be due to specific bindings involving sulfo groups and monoheteryl substitutes. Potentiometric titrations were conducted to determine pKa values reflecting the protonation process.

Summary: In this study, the structural, thermal, linear, third order nonlinear (NLO), and optical limiting (OL) properties of an organic dye filled Mn: ZnS/PMMA polymer nanocomposite (PNCs) were investigated. Various techniques including FTIR, XRD, SEM, TEM, DSC, TGA, and UV-Vis spectroscopy were used to determine the properties of the PNCs. The PNCs exhibited strong fluorescence emission and showed promising potential for optoelectronic and photonic applications. The NLO properties were explored using a Z-scan technique and the PNCs demonstrated strong optical limiting behavior.

Summary: Multiphoton absorption is important in various applications, but its weak process limits its practicality. This study demonstrates that placing a multiphoton absorbent in an imbalanced nonlinear interferometer can enhance the precision of multiphoton cross section estimation. The sensitivity can be increased by 1 order compared to transmission measurements, and the measurement precision is robust against experimental imperfections that cause photon losses.

Summary: This study compared two types of dye-labeled nanoparticles and found that nanoparticles with dye molecules in a solid state undergo dye quenching, while those in a soluble state do not. To standardize the comparative study, the proposed solutions include using lower dye loading or utilizing medium analysis for quantifying cell uptake of nanoparticles. Valuable insights into selecting valid quantification methods for bio-nano studies are provided.

Summary: A series of V-shaped donor-n-acceptor-n-donor compounds with an aldehyde group were designed, synthesized, and evaluated as two-photon excited fluorescence probes for selective detection of cysteine. The structures were characterized and their electronic structures were studied. Two compounds, 1Pip and 3TEG, showed high selectivity, good anti-interference ability, and favorable two-photon absorption performance for detecting cysteine. Cell fluorescence imaging experiments showed that 3TEG had better cellular membrane permeability and could visualize endogenous and exogenous cysteine in living cells. These results suggest that 3TEG has potential as a two-photon fluorescence probe for detecting cysteine in biological samples.
