Abstract

The fluorescent conjugated polymer-silica hybrid film with enhanced emission and enhanced chemical resistance via a facile method has been reported. Poly[ l-phenyl-2-(p-trimethylsilyl)phenylacetylene] PTMSDPA is also well-known as a florescent conjugated polymer with an extremely large fractional free volume (FFV) of about 0.26 in film. The chemical resistance of the PTMSDPA film is also expected to be enhanced due to the protecting effects of the silica gel incorporated in the polymer film. This emission enhancement is ascribed to quenching sites degeneration by the swelling-induced chain entanglement relaxation. The newly formed PTMSDPA silica hybrid film hardly dissolved in organic solvents. The hybrid film semi-permanently retained the enhanced emission due to the in situ organic inorganic hybridization. The present SCA treatment technique is also expected to facilitate multilayer lamination on PTMSDPA film due to the enhanced chemical resistance.
