摘要：

Application of a hydrostatic pressure in the range of 1-650 atm boosted photoluminescence and electroluminescence of hexaphenylsilole by similar to 10 and similar to 73%, respectively, due to the suppression of intramolecular rotations and/or the increase in carrier injection, offering a helpful mechanistic insight into the intriguing phenomenon of aggregation-induced emission.
