AN APPROACH TO PORPHYRIN-BASED MOLECULAR WIRES - SYNTHESIS OF A BIS(PORPHYRIN)TETRAONE AND ITS CONVERSION TO A LINEARLY CONJUGATED TETRAKISPORPHYRIN SYSTEM

An approach to molecular wires based on quasi-one-dimensional linearly conjugated poly-porphyrin systems is outlined and a rationally designed synthesis of the tetrakisporphyrin 9, a strand some 65 angstrom in length, via the bis(porphyrin)tetraone 2 is described.
