A synthetic strategy for the construction of a novel series of rigid supramolecular triads

A method is described for constructing totally rigid triad(trichromophoric) supramolecular systems, D2–B1–D1–B2–A, in which the chromophores D2(dimethylaniline), D1(dimethoxynaphthalene), and A(dicyanovinyl) are fused to bridges, B1 and B2, consisting of linearly fused norbornyl and bicycle[2.2.0]hexanyl units.
