cze	Push-pull chromofory na bázi dikyanpyrazinu pro vysoceúčinnou fotoredoxní katalýzu	Byly připraveny push-pull chromofory na bázi dikyanpyrazinu (DPZ) jako nové typy fotoredoxních katalyzátorů. DPZ deriváty obsahující 2-methoxythienyl substituent jako elektrondonorní jednotku vykazují široký absorpční pás až k 500 nm a vynikající redoxní vlastnosti - byly testovány jako redox katalyzátory při čtyřech typech fotoredoxních reakcí.	dehydrogenační coupling reakce, fotokatalýza, C-H funkcionalizace, elektron transfer, singletový kyslík, oxidativní hydroxylace, arylboronové kyseliny, komplex
eng	Dicyanopyrazine-derived push-pull chromophores for highly efficient photoredox catalysis	Here, we report dicyanopyrazine (DPZ)-derived push-pull chromophores, easily prepared and tunable organic compounds, as new kinds of photoredox catalysts. In particular, the DPZ derivative H, containing 2-methoxythienyl as electron-donating moiety, exhibits a broad absorption of visible light with an absorption edge up to 500 nm and excellent redox properties, and has been demonstrated as a desirably active and efficient photoredox catalyst in four challenging kinds of photoredox reactions. The amount of catalyst in most reactions is less than 0.1 mol% and even 0.01 mol%, representing the lowest catalyst loading in the current photoredox organocatalysis.	bond-forming reactions; dehydrogenative coupling reactions; visible-light photocatalysis; c-h functionalization; electron-transfer; singlet oxygen; oxidative hydroxylation; arylboronic acids; lifetime; complex
