Synthesis of 2H,9H-naphtho[2,3-b:7,6-b′]dipyran-2,9-diones as potential DNA-reactive agents
摘要:
New 2H,9H-naphtho[2,3-b:7,6-b']dipyran-2,9-diones have been synthesized. The tetracyclic derivatives were obtained by two different synthetic pathways, both having, as a common intermediate, the 3,6-dihydroxynaphthalene-2,7-dicarboxaldehyde. (C) 1998 Elsevier Science S.A. All rights reserved.

aggregation: Examples of a novel class of tweezer molecules have been constructed through the tethering of two dipolar merocyanine chromophores. The electrostatic‐interaction‐directed self‐assembly of these tweezers affords centrosymmetric bimolecularcomplexes with a unique aggregate geometry of four π‐stacked chromophores (see picture) with an alternating arrangement of their dipole moments and very high dimerization
