Abstract
Aggregation-induced emissions of polymetalloles have been investigated since they are very attractive in their possible optoelectronic applications such as P-LED's and Sensors. Size of nanoparticulates was measured by using scanning electron micrograph and was about 200-300nm. Phenylmethylpolysilane (PMPS) and polymetalloles emit the light at 360nm and 520nm, respectively. However, the aggregates of polymetallole containing PMPS exhibit an enhanced emission band at 520nm, indicating that the energy transfer occurs from PMPS to polymetalloles in aggregates. Emission intensity of PMPS/polymetallole nanoparticulates at 520nm increases depending on the aliquot of PMPS.
