General description

The intensity of fluorescence peak of isoquinoline increases with increasing pressure in polymethylmethacrylate and in polyisobutylene polymeric media.

Application

Isoquinoline (isq) has been used:
  • in the preparation of cis-[(dcbH2)2Ru(isq)2](ClO4)2 [dcbH2 = 4,4′-(CO2H)2-2,2′-bipyridine]
  • to investigate the toxicity of three two-ring and five three-ring azaarenes to the green alga Scenedesmus acuminatus and its relationship with molecular structure
