Acceleration of Chemiluminescence Reactions with Coumarin-modified Polyhedral Oligomeric Silsesquioxane

Chemiluminescence has attracted much attention as a light source and an excitation mediator without electric power sources. To develop advanced optical materials, it is necessary to control the chemiluminescence behavior more precisely by molecular design. Herein, we describe influence of connection inorganic scaffold on properties with coumarin-modified polyhedral oligomeric silsesquioxane (D1421-POSS). Accordingly, when D1421-POSS was chemically excited using bis(2-carbopentyloxy-3,5,6-trichlorophenyl) oxalate (CPPO), shown that initiation chemical emission reactions accelerated POSS connection, comparing model compound D1421-arm. From cyclic voltammetry measurements, revealed oxidation potential significantly lower than these data, propose mechanism aggregation assisted core induces low potential, resulting in acceleration reactions. (POSS). found POSS.
