- Self-assembling, chromogenic receptors for the recognition of medically important substrates and their method of use
-
A chromogenic receptor comprises a self-assembled chromogenic compound having at least one intrinsic binding site. The chromogenic compound is characterized by the property of producing a reversible color change responsive to binding a target substrate to

- Synthesis of bis-porphyrins containing a 2,9-diphenyl-1,10-phenanthroline spacer
-
The synthesis of bis-porphyrins disposed in an oblique fashion is described. The tetrapyrrole rings are linked via a 2,9-diphenyl-1,10-phenanthroline spacer. Two routes have been investigated: a step wise procedure and a direct strategy involving a double cyclisation step. From the bis-free base porphyrin, synthesized with an overall yield of 1% from 2,9-di(p-tolyl)-1,10-phenanthroline, an unsymmetrical zinc (II) porphyrin free base system was prepared and isolated in view of excited state energy and electron transfer.

- SYNTHESIS OF AN OBLIQUE BIS-PORPHYRIN SYSTEM CONTAINING A 1,10-PHENANTHROLINE SPACER
-
A molecule consisting of two porphyrin rings (free base or Zn complex) rigidly held by a 1,10-phenanthroline nucleus has been made ; the centre-to-centre separation is about 13 angstroem.
