“…The intermediate formyl-calix[4]pyrrole was synthesized according to our previous reported paper. 7 Receptors 1 and 2 were obtained by the reaction of formyl-calix[4]pyrrole with 4-nitrophenylhydrazine and 2,4-dinitrophenylhydrazine in good yields. The purity and structure of compounds 1 and 2 were conrmed by the MS, 1 H NMR and 13 C NMR spectra.…”

“…As would be anticipated, extending the p-conjugation system with electron-rich imidazole and pyrrole rings through an ethenyl linker at the 3-position to form 57 and 58 results in a bathochromic shift which can be further fine-tuned by modifying the electron donating properties of the aryl group. 231,232 The merocyanine conjugated dye 59 displays a further large bathochromic shift to ca. 650 nm due to the extension of the p-conjugation system.…”

This review focuses on classifying different types of long wavelength absorbing BODIPY dyes based on the wide range of structural modification methods that have been adopted, and on tabulating their spectral and photophysical properties. The structure-property relationships are analyzed in depth with reference to molecular modeling calculations, so that the effectiveness of the different structural modification strategies for shifting the main BODIPY spectral bands to longer wavelengths can be readily compared, along with their effects on the fluorescence quantum yield (ΦF) values. This should facilitate the future rational design of red/NIR region BODIPY dyes for a wide range of different applications.

A novel meso-tetracyclohexylcalix [4]pyrrole-based boradiazaindacene dye 3 was synthesized and characterized. F − -binding properties of the dye in the presence of tetrabutylammonium (TBA + ), tetraethylammonium (TEA + ), and tetramethylammonium (TMA + ) counter ions were investigated by UV-Vis, fluorescence, and NMR spectroscopies. Dye 3 displayed various degrees of absorption red shift, fluorescence quenching, and downfield shifts of NH signals for the three fluoride salts. The association constants of these salts mainly depend on cation size effects and ion-pairing effects and were in the order K TMA+ > K TEA+ > K TBA+ . Thus, we speculate that both F − and tetraalkylammonium cations are concomitantly located above and below a bowl-shaped calix [4]pyrrole cup in an ion-paired complex, respectively.
