Synthesis and binding behavior of a Zn(II)-porphyrin having calix[5]arene cap

Macrocyclic Receptors for Identification and Selective Binding of Substrates of Different Nature

“…However, it has now turned in another direction as porphyrins can be used as selective molecular receptors for certain types of substrates [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ]. The fact that it is possible to chemically modify the tetrapyrrole molecule has enabled researchers to synthesize porphyrin conjugates with other macrocyclic compounds(porphyrin conjugates with calix[n]arenes [ 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 ], cyclodextrines [ 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , …”

“…Especially interesting among such compounds are covalently bound porphyrin-calix[4]arene macrocyclic receptors [ 8 , 10 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 ]. The first calix[4]arene-porphyrin conjugate capable of selectively identifying small organic molecules was described in [ 47 ].…”

Peroxidase-Like Catalytic Activity of Water-Insoluble Complex Linked Fe(III)-Thiacalix[4]arenetetrasulfonate with Tetrakis(1-methylpyridinium-4-yl)porphine via Ionic Interaction

“…[7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] Generally, these supramolecular complexes have been examined for their functions of forming host-guest complexes for various molecules and ions. 7,10,11,22) However, no report has been published on any enzyme-like activity of supramolecular complexes linked calix 25-27) Accordingly, if metal-thiacalix[n]arene could be linked with metal-porphyrins via ionic interaction, the supramolecular complexes produced would be a new artificial mimesis with two enzyme-like catalytic activities. However, even if two complexes independently exhibited high enzyme-like activity, each complex in the supramolecular complex would not necessarily maintain a correspondingly high enzyme-like activity.…”
