Claim 1:
2. The rigid macrocycle of claim 1,
wherein the PPNDI subunit comprises a PPNDI of formula, wherein each of R1, R2, R3, and R4 of the PPNDI 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, and a sulfate moiety and m is greater than or equal to 2 and less than or equal to 10;

wherein the NDI subunit comprises a NDI of formula, wherein each of R1, R2, R3, R4, R5, R6, R7, and R8 of the PPNDI 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, and a sulfate moiety;

wherein the macrocycle comprises the PMDI 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; and

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