ABSTRACTSolid sol of silver in poly(methyl methacrylate), Ag/PMMA, was prepared by bulk polymerization of methyl methacrylate solution of silver (I) triflluoroacetate (AgTfa) and followed by postheating. The formation of the metallic Ag nanocluster was characterized by visible spectroscopy, and effects of the concentrations of AIBN and AgTfa and the heat-treatment duration on the formation of Ag cluster were investigated. Furthermore, based on the kinetic study of MMA in the presence of AgTfa, possible mechanism for the reduction and agglomeration of silver is proposed.

The synthesis and optical characterization of novel single-benzene ESIPT-based fluorophores is described in solid state and in solution. Special attention is given towards the influence of their unique substitution pattern on their optical properties. Depending on this pattern, aggregation induced emission or aggregation caused quenching (ACQ) is observed in the solid state.<br>
