Cyclohexene‐Embedded Dicyanomethylene Merocyanines – Consecutive Three‐Component Coupling‐Addition Synthesis and Chromophore Characteristics [PDF]

open access: yesChemistryOpen, 2023
A concise and efficient consecutive three‐component alkynylation‐addition synthesis of cyclohexene‐embedded dicyanomethylene merocyanines furnishes a small library of dyes in moderate to excellent yield. The dyes possess strong absorption coefficients of

Reproducing the Solvatochromism of Merocyanines by PCM Calculations [PDF]

open access: yesMolecules
Polarizable continuum methods (PCM) have been widely employed for simulating solvent effects, in spite of the fact that they either ignore specific interactions in solution or only partially reproduce non-specific contributions.

Red-Shifted Environmental Fluorophores and Their Use for the Detection of Gram-Negative Bacteria [PDF]

open access: yesChemosensors, 2021
Two novel, water-soluble, merocyanine fluorophores were readily prepared by microwave-assisted synthesis. Full optical characterization was performed in a series of protic and aprotic solvents, and the dyes displayed fluorescence in the red region with ...

Synthesis and Acid-Responsiveness of an Insulated π-Conjugated Polymer Containing Spiropyrans in Its Backbone [PDF]

open access: yesMolecules, 2019
A π-conjugated polymer containing spiropyrans (SPs), which could be almost completely converted to protonated merocyanines (MCH+) and back to the SP form by adding an acid and a base, respectively, was developed.
