Abstract

The first neutral hexacoordinated silole complexes were synthesized. Substituent patterns govern coordination modes and influence delocalization within diketonato ligands, markedly affecting photophysical properties and enabling charge-transfer excitations. This structural tunability provides a strategy to modulate the electronic and photophysical behavior of silole-based complexes, expanding their potential applications.
