Synthesis and electrochemical investigation of β-alkyloxy substituted meso-tetraphenylporphyrins

The synthesis of β-alkyloxy substituted tetraphenylporphyrins is described. Due to interaction between the β-alkyloxy substituent and the meso-phenyl moiety the porphyrins are slightly non planar. The deviation from planarity in these compounds is investi

New synthetic pathway leading to oxospirochlorins

In this work we propose a completely new approach for the synthesis of spirochlorin derivatives based on the use of an imino-keto intermediate formed in situ from 2-amino-5,10,15,20-tetraphenylporphyrins and inverse electron demand Diels-Alder (iEDDA) cyc

Correlations between functional porphyrin positions and accumulation in cancer cells

Porphyrin is accumulated in tumours due to its interaction with protein. Cancer therapy with porphyrin as a carrier molecule is attracting attention. Porphyrin displays two functional sites termed β- and meso-positions. A correlation between the functiona

Exciton-Coupled Circular Dichroism Characterization of Monotopically Binding Guests in Host?Guest Complexes with a Bis(zinc porphyrin) Tweezer

A stiff-stilbene-linked bisporphyrin tweezer with inherent helicity was used for exciton-coupled circular dichroism (ECCD) characterization of a series of monotopically binding amine guest molecules. CD signals were observed for a variety of monoamines at relatively low tweezer/amine (host/guest) ratios between 1 : 10 to 1 : 70. For the amines producing the most intense CD signals, a binding stoichiometry of 1 : 2 was found. A likely explanation is the presence of guest-guest interactions in the complexes. This is supported by the correlation observed between CD signal intensity and magnitude of possible noncovalent binding between the guests, which can be divided into three groups showing no, moderate and strong response, respectively. Further support for this rationalization comes from molecular modelling.

Conformational restriction of flexible molecules in solution by a semirigid bis-porphyrin molecular tweezer

A semirigid bis-porphyrin molecular clip with a glycoluril backbone has been synthesized. The clip provides an adaptable molecular cavity for binding of diamines. Binding constants for diamines of 104-107 M-1 are orders of
