paper reports an investigation of photochemical cyclodehydrogenation for the preparation of polycyclic azaarenes. Various naphthoquinolines and naphthoisoquinolines were obtained from 2-, 3-, and 4-[2-(1- and 2-naphthyl)vinyl]pyridine. 4-[2-(3-Phenanthryl)vinyl]pyridine gave pyreno[1,10- HIJ]isoquinoline. An efficient preparation of (2-arylvinyl)pyridines is described.

with a 1:1 mixture of the constituting components. This contrasting behavior has been interpreted taking into consideration the difference in the entropy change associated with the complexation process. Based on the effect of solventpolarity on the absorption and emission behavior of the complex and taking into consideration the molecular geometry, it is concluded that the interaction between the aromatic
