    摘要: Macrocycle compounds of precise molecular geometry are disclosed and claimed, useful for a variety of purposes including membranes, molecular recognition and any other purpose where specific molecular macrogeometry is important. Most preferably, the macrocycles are of the imide class, formed by way of reactions of diamines with .alpha.-anhydride, .omega.-nitro compounds, followed by cyclization with an acid chloride.
