Enhancement of association constants of various charge-transfer complexes in siloxane solvents

Abstract

The association constants of various charge-transfer complexes were evaluated in n-hexane, octamethyltrisiloxane and PDMS to investigate the solvent effect. Higher association constants were observed in siloxanes. The association constant in PDMS increased (1.8–5.7 times) with increasing aromatic core size, implying the significant influence of aromatic cores on the solvent effect.
