The incorporation of silole-based lumophores into a photoactive organic–inorganic ureasil host via covalent grafting or physical mixing results in enhanced photoluminescence through aggregation and host–guest energy transfer.
A series of 2,5-diaryl-3,4-diphenylsiloles, with various mono-substituted phenyl groups, extended pi-conjugated groups, and heteroaryl groups as aryl groups at the 2,5-positions, has been prepared by a one-pot synthesis from bis(phenylethynyl)silanes based on the intramolecular reductive cyclization followed by the palladium-catalyzed cross-coupling with aryl halides.
