Claim 2:
3. The rigid macrocycle of claim 2, wherein the macrocycle comprises the PPNDI of formula, wherein each of R1, R2, R3, and R4 of the NDI subunit is independently selected from the group consisting of hydrogen, a halogen, an alkyl moiety, an alkenyl moiety, an alkynyl moiety, a hydroxyl moiety, an alkoxy moiety, a phenoxy moiety, a carbonyl moiety, a cyanide moiety, a sulfate moiety;
wherein the PMDI subunit comprises a NDI of formula, wherein each of R1 and R2 of the PMDI subunit is independently selected from the group consisting of hydrogen, a halogen, an alkyl moiety, an alkenyl moiety, an alkynyl moiety, a hydroxyl moiety, an alkoxy moiety, a phenoxy moiety, a carbonyl moiety, a cyanide moiety, a sulfate moiety; or

wherein the three chiral linking subunits are (i) a (RR)-trans-1,2-cycloalkyl subunit, or (ii) a (SS)-trans-1,2-cycloalkyl subunit.
