  nanoaggregation, as confirmed by the changes in the UV-vis and emission spectra, and light scattering techniques. The nanoaggregates exhibit time-dependent emission characteristics and can serve as sensors for the detection of nitroaromatic compounds. The selective detection of picric acid (PA) over other nitroaromatic compounds by 1–3 is attributed to the photoinduced electron transfer from the trispyrazole to
