AB  - Cucurbit[8]uril (CB[8]) mediated assembly of extended aryl viologens (EVs) into 
      optically tunable dimers is reported for the first time. We show that the modular 
      design and synthesis of a new class of pi-conjugated viologen derivatives with 
      rigid aromatic or heteroaromatic bridging units as well as electron donating 
      molecular recognition motifs enable their self-assembly into 2 : 2 complexes with 
      CB[8]. The quantitative dimerization process involving these two molecular 
      components in an aqueous solution enables excimer-like interactions between 
      closely packed charged guests giving rise to distinct spectroscopic behavior. The 
      nature of these dimers (CB[8](2).(EV[X]R)(2)) in the ground and excited states 
      was characterized by NMR, isothermal titration calorimetry, and steady-state 
      spectroscopic measurements.
