Abstract

Aggregation of some nitrogen‐containing heterocyclic compounds have been investigated by means of fluorescence spectroscopy in aqueous or aquiorgano binary mixtures of different Φ values for the first time. The aggregators studied are __N‐__butylcarbazole (CBZ‐4), N‐octylcarbazole (CBZ‐8), __N‐__dodecylcarbazole (CBZ‐12), and N‐hexadecylcarbazole (CBZ‐16). Their aggregating tendencies have been evaluated by measuring their critical aggregate concentration values (CAgC's). Our results indicate that the N‐alkylcarbazoles, just like the anthracene derivatives with different chain‐lengths, can also be used as fluorescence probes for evaluating aggregating tendencies or CAgC values.
