Electrochemical and aggregation properties of newly synthesized dendritic axially morpholine-disubstituted silicon phthalocyanine, mono-substituted subphthalocyanine and their quaternized derivatives

Synthesis and Characterization of B/NaF and Silicon Phthalocyanine-Modified TiO2 and an Evaluation of Their Photocatalytic Removal of Carbamazepine

“…Such additional defects may be responsible for the existence of new weakly bound surface oxygen species not available in pure TiO 2 . TiO 2 , as studied thoroughly in the literature, revealed O1s signals at 529 and 531 eV attributed to Ti-O and -OH groups respectively[6,30,36].…”

“…C-NMR spectrum (Figure S3): the signals observed at 162.98 ppm of azomethine carbon on imine fragment and the signals at 63.57, 62.03, 56.09, 54.68, and 29.44 ppm related to the presence of aliphatic carbons in the structure; (iv) 1 H-NMR spectrum of compound (3) in D 2 O (FigureS4): the disappearance of aromatic OH at 11.41 ppm and aliphatic OH at 4.85 ppm[13,29,30]; and (v) mass spectral analysis (FigureS5): the presence of the signal at m/z 282.28 related to [M + 2Na] + ion peak.…”

Recent advances in subphthalocyanines and related subporphyrinoids

“…Substitution of the axial chlorine ligand in the presence of alkyl alcohols is normally carried out in boiling toluene, with reaction times varying from 24 and 72 hours. 134–140 The use of higher boiling solvents such as o -DCB 15 or the addition of a base to neutralize the generated HCl ( e.g. K 2 CO 3 ), 136 have also been reported.…”

“…Treatment with sodium chlorite in the presence of sulfamic acid as hypochlorite scavenger has been employed for the oxidation of the axial hydroxybenzaldehyde group to the carboxyl derivative. 47,117 Reduction of the axial nitrophenoxy group with molecular hydrogen, 97,100 alkylation of the axial aminophenoxy ligand with propanesultone to afford the corresponding alkylsulfonate species 97 and quaternization of tertiary amines in the axial moiety with methyl iodide 134 have also been reported, as well as acylation with protected acids using EDC and NHS as coupling agents 100 or reaction with succinic anhydride. 108 The amino functionality of the apical aminophenoxy group has been used as nucleophile with triflate-activated SubPcs to form nitrogen-bridged SubPc dimers.…”

Photophysical properties of a newly synthesized unsymmetrically substituted zinc phthalocyanine

“…These studies show that morpholine groups positively change the biological activity of Pcs (22). In addition, axially morpholine-disubstituted silicon phthalocyanines exhibited better antifungal photodynamic activity and DNA/BSA binding (23)(24)(25).…”
