Nowadays organosilicon luminescent materials are of increasing interest due to the variety of their synthetic or modification tech-niques and application fields.Ladder polyphenylsilsesquioxanes(L-PPSQ)are a unique class of organosilicon polymers,which can be ideal matri-ces for the luminescent composites due to their high thermal stability,optical transparency and mechanical strength.In this work,new mechani-cally strong,heat-resistant,transparent and sensitive to ammonia vapor luminescent composite films based on L-PPSQ have been obtained.As the source of Europium ions oligophenyleuropiumsiloxane was used,demonstrating perfect compatibility to the matrix due to the similar nature.To improve luminescent properties of the films,new organosilicon ligands were introduced into the composites and their influence on the prop-erties of the materials was studied.Valuable properties of described composites may allow their further application as multifunctional coatings.
