✦ Synopsis

A multicomponent molecular recognition process leads to a self‐assembled “quaternary” supramolecular complex formed from porphyrins and an “unusual” poly(A·A·U) triple helix. The formation of this superstructure is promoted by porphyrin aggregation and a number of recognition processes (Watson‐Crick and Hoogsteen pairing, coulombic interactions, and stacking interactions).

## Abstract The Zimm‐Bragg theory is extended to treat the melting of the triple helix poly (A + 2U) for a solution with a 1 : 2 mole ratio of poly A to poly U. Only the case for long chains is considered. For a given set of parameters the theory predicts the fraction of segments in the triple heli
