Synthesis and characterization of metal-free and metallo-phthalocyanines with four pendant coumarinthio/oxy-substituents

Synthesis and characterization of novel flavonoid-substituted phthalocyanines using (±)naringenin

“…Some characteristic shifts which belong to the compounds can be seen at Table 3. In addition, the 1 H and 13 C NMR results of the compound 3 and 4 are in good agreement with the published literature [24][25][26].…”

Synthesis, characterization, spectroscopic and electrochemical properties of phthalocyanines substituted with four 3-ferrocenyl-7-oxycoumarin moieties

“…Due to the ferrocenyl moieties, the Q band (675 nm in DMF) is substantially blue-shifted (14 nm) by comparing with the 2 (3),9(10),16 (17),23(24)-tetrakis(7-oxy-4-methylcoumarin)phthalocyaninato zinc(II) (5) (689 nm in DMF) (Fig. 3) [37]. Fig.…”

Insight on Mercapto-Coumarins: Synthesis and Reactivity

“…Novel metal-free and metallophthalocyanines with 7-thioether-4-methyl coumarin were prepared from the reaction of 7-mercapto-4-methyl coumarin ( 50 ) with 1,2-dicyano-4-nitrobenzene ( 99 ) to give 7-(3,4-dicyanophenylthio)-4-methyl coumarin (100) ( Scheme 37 ) [ 92 ]. Cyclotetramerization of this structure under heating with dry 2- N , N -dimethylaminoethanol in a sealed tube afforded 2,9,16,23-tetrakis(7-coumarinthio-4-methyl)-phthalocyanine ( 101a ).…”
