Claim 4:
5. The rigid macrocycle of claim 2,
wherein the macrocycle comprises the PPNDI 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 NDI 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; 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.
