Summary: Push-pull fluorophores containing a 2,2'-bipyridine acceptor with carbazole/fluorene groups exhibited good fluorescence performance with high fluorescence quantum yields and large Stokes shifts. The solvatochromic method was successfully applied to evaluate their hyperpolarizability coefficients. Two-photon emission cross sections were measured, confirming the greatest charge separation in carbazole-substituted isomers. The fluorene-containing fluorophores showed a planarized ICT process and can be used as environment polarity-sensitive fluorescent dyes and probes for detecting structural changes in proteins/biomolecular interactions and optical switches.

Summary: In this study, poly(epsilon-caprolactone) copolymers decorated with randomly included thermally stable and photo-dimerizing cinnamoyl groups were synthesized. The copolymers remained processable at high temperatures due to the absence of thermal reactions between cinnamoyl groups, and UV curing improved the properties of the films. The random inclusion of photo-reactive co-units enriched the thermodynamic state of the polymer and promoted the formation of various microstructures.

Summary: New fluorescent nucleobase analogues (FBAs) have proven to be valuable tools for DNA labelling technologies. Among the newly synthesized FBAs, the highly fluorescent adenine analogue 2-aminopurine (2AP) is widely used, but its UV excitation poses a risk to living cells. New derivatives of 2AP with high fluorescence were synthesized using a simpler method. These compounds have superior photophysical properties, such as absorption and emission in the visible region, high fluorescence quantum yields, and large Stokes' shifts, particularly in non-protic organic solvents. Computational calculations were performed to predict their absorption and emission spectra. Furthermore, these compounds showed little to no toxicity in yeast cell assays.

Summary: Despite the progress in OLEDs, producing blue OLEDs with sufficient color purity, stability, and efficiency remains challenging. The introduction of an additional benzene moiety in the designed materials DtCz-TRZ and mDtCz-TRZ allows for hindering structural relaxation and spectral redshift, enabling efficient deep blue emission. The TADF-OLEDs achieved a maximum external quantum efficiency of 9.37% with an emission peak at 455 nm, while the TSF-OLED based on mDtCz-TRZ showed an EQEmax of 15.31% with an electroluminescence spectrum peak at 473 nm. These blue TADF materials have demonstrated superior performance in OLEDs, validating their versatile applications.

Summary: Xanthene dyes have remarkable photophysical properties and photostability, making them promising candidates for imaging/sensing/tracking/labeling probes. However, their emission wavelength ≤ 600 nm and small Stokes shift restrict their use in biological applications. This review provides a comprehensive list of deep red to NIR xanthene-hemicyanine and xanthene-coumarin hybrids, along with synthetic strategies and discussions on the effects of substituents, pi-conjugation, and ring structure on their photophysical properties. Applications of these hybrids based on fluorophore-linker strategy and spirocyclization are also discussed. This review emphasizes the structure-spectroscopic relationships, which will aid in the design of new deep red to NIR xanthene analogs.

Summary: This study found that benzothiazole is responsible for enhancing the fastness properties of dyes. Comparison of the total electronic energies revealed that the benzothiazolyl series is more stable than the naphthol series. Frontier Molecular Orbitals (FMOs) showed charge transfer in benzothiazole-containing compounds but not in the naphthol series. Among the benzothiazolyl isomers, the hydrazone form was found to be the most stable and responsible for fluorescence possession. The HOMO-LUMO energy band gap confirmed the same. Both series had positive electrophilicity index and hyper-hardness values, indicating photo stability and reactivity. Thus, the benzothiazolyl series was found to be more stable and had enhanced light fastness.
