The invention provides for tripyrrane compounds of the formula ##STR1## wherein: each Q represents, typically, an alkyl group, cycloalkyl group, aryl group, or a heteroaryl group; and each R represents hydrogen, an alkyl group, alcohol group, or a carbonyl-containing group. Additionally, there are described methods to prepare such compounds, for example, comprising the steps of:
