Hybrid of Indolizine and Merocyanine-A New Class of Organelle-Specific Dyes. [PDF]

Angew Chem Int Ed Engl
The new merocyanines and cyanines possessing an indolizine scaffold were synthesized via tandem Friedel–Crafts alkylation followed by nucleophilic aromatic substitution, by leveraging the special reactivity of 2,3,5,6‐tetrafluoro‐4‐hydroxybenzaldehyde.

Synthesis, Photophysical Properties, and Practical Hg(II)-Sensing Applications of a Rigidified Phenolo-Merocyanine Dye. [PDF]

Chem Asian J
Rigidity for performance!!! A novel conformationally restrained phenolic merocyanine was synthesized in order to obtain a fluorogenic dye with outstanding spectral properties at physiological pH (fluorescence brightness > 71,000 M−1 cm−1). The utility of its optically tunable hydroxyl group was illustrated with a thiophosphinate‐based chemodosimeter ...

Cyanines Substituted on the Polymethine Chain: Synthesis, Resulting Properties, and Application Use Cases. [PDF]

Chempluschem
Cyanines are small‐molecule dyes with a polymethine chain. For various applications, their properties can be tuned by varying not only chain length and auxochrome end groups but also the substituents on the polymethine chain. Here, we review the synthesis, properties, and applications of cyanines with substituents on the polymethine chain.

Biocompatible Ink Optimization Enables Functional Volumetric Bioprinting With Xolography. [PDF]

Adv Mater
Xolography's reliance on weak‐base co‐initiators introduces unique biochemical constraints. By dissecting the effects of extracellular pH, osmolality, and lysosomotropic stress, this study defines the biochemical design space that enables fully biocompatible, cell‐laden volumetric printing. Abstract Xolography is a novel linear volumetric manufacturing

Spiropyran modified micro-fluidic chip channels as photonically controlled self-indicating system for metal ion accumulation and release [PDF]

, 2009
In this paper, we show how through integrating the beneficial characteristics of micro-fluidic devices and spiropyrans dyes, a simple and very innovative chip configured as an on-line photonically controlled self-indicating system for metal ion ...

Reversible low-light induced photoswitching of crowned spiropyran-DO3A complexed with gadolinium(III) ions. [PDF]

, 2012
Photoswitchable spiropyran has been conjugated to the crowned ring system DO3A, which improves its solubility in dipolar and polar media and stabilizes the merocyanine isomer. Adding the lanthanide ion gadolinium(III) to the macrocyclic ring system leads

Theoretical Study on the Optoelectronic Properties of Merocyanine-Dyes

The Journal of Physical Chemistry A, 2023
Merocyanines, as prototypes of highly polar π-conjugated molecules, have been intensively investigated for their self-assembly and optoelectronic properties, both experimentally and theoretically. However, an accurate description of their structural and electronic properties remains challenging for quantum-chemical methods.

The dependence of the molecular first hyperpolarizabilities of merocyanines on ground-state polarization and length [PDF]

, 1994
We report here the dipole moment (µ) and first hyperpolarizability (β) determined by electric field-induced second harmonic generation, for several merocyanine dyes containing an 1,3,3-trimethylindoline heterocycle as a ‘donor’ in which the ‘acceptor ...

Molecular First Hyperpolarizabilities of a New Class of Asymmetric Squaraine Dyes [PDF]

, 1994
The molecular first hyperpolarizabilities (β) of a series of asymmetric squaraine dyes have been measured by electric-field-induced second harmonic generation; the dyes have negative β-values whose magnitudes are comparable to 4-N,N-dimethylamino-4 ...
