Fluorescent carbazole oligomers nanofibril materials for vapor sensing

摘要

A fluorescence based sensor (10) is disclosed and described. The sensor (10) can include nanofibril materials (12) fabricated from a linear carbazole oligomer and a fluorescence detector (14). The linear carbazole oligomer can have the formula (I) wherein n is 3 to 9, R are independently selected amine sidegroups, and at least one, but not all, R is a C1 to C14 alkyl. The carbazole-based fluorescence based sensors (10) can be particularly suitable for detection of explosives and volatile nitro compounds.;
