## Abstract Aggregation of some nitrogenโcontaining heterocyclic compounds have been investigated by means of fluorescence spectroscopy in aqueous or aquiorgano binary mixtures of different ฮฆ values for the first time. The aggregators studied are __Nโ__butylcarbazole (CBZโ4), __N__โoctylcarbazole (

## Abstract 9โNitrocarbazole (**1**) was prepared and rearranged to give a mixture of 1โnitroโ (**2**) and 3โnitrocarbazole (**3**) in the same ratio as observed in the case of the carbazole nitration. The evidence for the formation of **1** during the nitration of carbazole in acetic acid is given
Abstraet--Carbazole units in copolymers can be cross-linked by reaction with a Lewis acid catalyst in methylene chloride. The reaction initially causes gel formation, followed by the development (with BF3. Et20) of a characteristic blue colour. The blue product has been shown to be a cationic dye of
