| Research Abstract |
The synthesis of dibenzosiloles and -germoles obtained through an intramolecular Pd-catalyzed cyclization pathway is studied. Compared with the conventional synthetic strategies for achieving siloles and germoles, the present cyclization has several advantages in terms of functional group tolerances. The luminescence properties could be tuned through the molecular structure, particularly the electronic effects of the substituents. The remarkably high efficiency of the solid-state fluorescence, with a longer emission shift observed for the compounds having ester moiety, was achieved through the formation of a J-type aggregation structure. The structure-property relationships described herein will be valuable for the future design and synthesis of new organic electroluminescent materials containing Group 14 metalloles as a key building unit.
