The spatiotemporal sensing of specific cationic and anionic species is crucial for understanding the processes occurring in living systems. Herein, the authors developed new fluorescence sensors derived from tetrapyrazinoporphyrazines (TPyzPzs) with a recognition moiety that consists of an aza-crown and supporting substituents. Their sensitivity and selectivity were compared by fluorescence titration experiments with the properties of known TPyzPzs (with either one aza-crown moiety or two of these moieties in a tweezer arrangement). Method of standard addition was employed for analyte quantification in saliva. For K+ recognition, the new derivatives had comparable or larger association constants with larger fluorescence enhancement factors compared to that with one aza-crown. Their fluorescence quantum yields in the ON state were 18× higher than that of TPyzPzs with a tweezer arrangement. Importantly, the sensitivity toward cations was strongly dependent on counteranions and increased as follows: NO3- < Br- < CF3SO3- < ClO4- ≪ SCN-. This trend resembles the chaotropic ability expressed by the Hofmeister series. The high selectivity toward KSCN was explained by synergic association of both K+ and SCN- with TPyzPz sensors. The sensing of SCN- was further exploited in a proof of concept study to quantify SCN- levels in the saliva of a smoker and to demonstrate the sensing ability of TPyzPzs under in vitro conditions.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system.

Base catalyzed intermol. cyclization of 2-amino-3-chloro-5,6-dicyanopyrazines I (R = H, Me, Ph, 4-BuC6H4, etc.) gave 5,10-disubstituted-2,3,7,8-tetracyano-5,10-dihydrodipyrazino[2,3-b:2′,3′ -e]pyrazines II. These compounds have rather small mol. size but have strong intramol. charge-transfer chromophoric system. They have strong fluorescence in solution and some have fluorescence even in the solid state which are very important to evaluate their electroluminescence property as an emitter for electroluminescence devices. The phys., structural, and electronic properties of these new 2,3,7,8-tetracyano-5,10-dihydrodipyrazino[2,3-b:2’3′-e]pyrazines were studied using UV-visible spectroscopy and the PPP MO calculation method.

A series of dicyanopyrazine and dicyanoimidazole derived push-pull mols. have been prepared and further investigated as photoredox catalysts. The fundamental properties of the catalysts were studied by DSC, X-ray anal., absorption/emission spectra, and electrochem. and were completed with the DFT results. The catalytic activity has been evaluated in visible light induced α-functionalization of amines (cross-dehydrogenative coupling and annulation reaction of tetrahydroisoquinolines). Thorough structure-property-catalytic activity relationships were elucidated.

Compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile, is researched, Molecular C6Cl2N4, CAS is 56413-95-7, about Effective Monofunctional Azaphthalocyanine Photosensitizers for Photodynamic Therapy. Author is Zimcik, Petr; Miletin, Miroslav; Novakova, Veronika; Kopecky, Kamil; Nejedla, Marcela; Stara, Vendula; Sedlackova, Katerina.

In this work we present a rational design of the active part of third generation photosensitizers for photodynamic therapy based on phthalocyanine and an azaphthalocyanine core. The preferred zinc complexes of the AAAB type that contain bulky tert-butylsulfanyl substituents (A) and one carboxy group (B) have been synthesized by statistical condensation and fully characterized. The tetramerization was performed using magnesium(ii) butoxide followed by demetalation and insertion of ZnII. Compound 1 synthesized from 4,5-bis(tert-butylsulfanyl)phthalonitrile (A) and 2,3-dicyanoquinoxaline-6-carboxylic acid (B) exerted very promising photophys. properties (Q-band absorption at 726 nm, ε = 140000 M-1 cm-1), which allowed strong absorption of light at long wavelengths where the penetration of the light through human tissues is deeper. The very high singlet oxygen quantum yield of 1 (ΦΔ = 0.80) assures efficient photosensitization. As a result of bulky peripheral substituents, compound 1 shows good solubility in organic solvents with a low degree of aggregation, which makes it potentially viable for noncomplicated modification. One carboxy group in the final structure of 1 allows simple binding to possible carriers. This compound is suitable for binding to targeting moieties to form the highly active part of a third-generation photosensitizer.
