A series of novel dendritic carbazole-functionalized subporphyrins, T(Cz-Gn)SubPs (n = 1–3), have been synthesized from pyridine–tri(pyrrol-1-yl)borane and the corresponding aldehydes. This study has demonstrated that intramolecular energy transfer from the carbazole dendron to the subporphyrin core occurs with a high efficiency which decreases with increasing dendron generation, in accord with the
The first rigid dendritic gel with strong emission based on oligocarbazole was reported. It is interesting that the second generation of dendron exhibited gelation ability under ultrasound, and two-component gel could be formed from the first generation of dendron assisted by 1,6-diaminohexane.
