Intercalation of aminophenyl- and pyridinium-substituted porphyrins into zirconium hydrogen phosphate: evidence for substituent-derived orientational selectivity

Preparation and structure of a new layered organic–inorganic hybrid between the protonated form of a perovskite Bi2SrTa2O9 and tetraphenylporphyrin by the intercalation behavior

“…Porphyrins are considered as excellent photosensitizers due to their catalytic activity and photoactive properties [5,6]. Tetraphenylporphyrin (TPP) is one member of the large porphyrin family.…”

Fabrication and spectroscopic properties of a metalloporphyrin-intercalated zirconium phosphate assembly

“…Groves and Thompson have synthesized porphyrin-intercalated a-ZrP by exchanging aminophenyl-and pyridiniumsubstituted porphyrins into the p-methoxyaniline-preintercalated complex a-ZrP?2PMA. 24 But the spectroscopic properties of the chromophores were not mentioned. In recent years, our group investigated the luminescence properties and energy transfer of metal-free porphyrin after binding to a modified cetyltrimethylammonium zirconium phosphate (abbreviated as CAZrP).…”

Incorporation of the Polyphenoloxidade Enzyme in Lamellar Calcium Phosphate

“…A utilização do estudo da intercalação serve para verificar o comportamento ou a orientação do hóspede dentro do espaço interlamelar. Como os efeitos interativos entre as lamelas dos fosfatos são fracos, a distância entre as mesmas pode ser facilmente aumentada, para proporcionar uma melhor acomodação das moléculas intercaladas (Kim et al, 1993, keller et al, 1994, Suárez et al, 1997, Ogawa et al, 1997, Ferreira et al, 1994. As moléculas hóspedes incluídas, por exemplo, um complexo metálico tris(diimina), ciclodextrina ou enzimas, podem se ligar eletrostaticamente ou por interações de van der Waals, com as lamelas ativadas em ambos os lados.…”
