Microwave-assisted synthesis and reverse saturable absorption of phthalocyanines and porphyrins

Microwave-assisted synthesis of phthalocyanine–porphyrin complex and its photoelectric conversion properties

“…Phthalocyanines (Pc) and porphyrins (Por) are versatile industrial materials and have attracted much attention for many years because of their wide applications such as light-emitting diodes [1,2], photodynamic therapy [3], molecular thermometers [4], magnets [5], and optical limiting devices [6]. Recently, they have been discovered to be p-type photoconductors and applied for solar cells [7,8].…”

“…: C, 85.88; H, 7.45 ; N, 6.68. Found: C, 85.72; H, 7.33; N,6.52%. were ground together in a quartz vessel of 50 mL, poured into DBU (5 mL), and irradiated in a microwave oven at 440 W for 10 min.…”

A new one pot and solvent-free synthesis of nickel porphyrin complex

“…Without DBU, this reaction does not proceed. The mechanism has been reported, explaining the essential role of DBU in the conversion of metal-free porphyrins into metalloporphyrins (26,27).…”

Microwave-assisted synthesis and characterization and theoretical calculations of the first example of free and metallophthalocyanines from salen type Schiff base derivative bearing thiophen and triazole heterocyclic rings

“…These were accomplished by a base catalyzed nucleophilic aromatic nitro displacement of 4-nitrophthalonitrile with (2) [20,21]. Similarly, Comparison of the IR spectral data clearly indicated the formation of compound (3) by the disappearance of the O-H band of (2) at 3590 zand 1352 cm À1 and of NO 2 band of (2a) at 1519 and 1333 cm À1 , and the appearance of a new absorption at 2230 cm À1 (C"N).…”
