Abstract

We report here the synthesis and structural characterization of a novel expanded Schiff base oligopyrrolic macrocycle TxLH ([Formula: see text] compound 2) along with its smaller congener hemi-TxLH ([Formula: see text] compound 1). The solid-state structure of TxLH is reminiscent of the shape of a Texas Longhorn[Formula: see text]. It thus defines a new architectural form for porphyrin analogues. The present study thus underscores the potential of using functionalized oligopyrroles as readily accessible molecular building blocks for the construction of structurally non-trivial molecules.
