New photoluminescent and nanoscale poly(tetraphenylsilole) siloxane nanoaggregates for the detection of 2,4,6-trinitrotoluene (TNT) were developed by using aggregation-induced emission property. Poly(tetraphenylsilole) siloxane nanoaggregates exhibited that photoluminescence (PL) intensity was increased when the water fraction was increased to 90% by volume. Relative PL efficiency of poly(tetraphenylsilole) siloxane nanoaggregates was exponentially increased to the percent of water fraction and particle diameter was dependent on solvent composition. Particle size of poly(tetraphenylsilole) siloxane nanoaggregates was tuned by controlling the water fraction by volume. Poly(tetraphenylsilole) siloxane nanoaggregates showed neither further aggregation nor degradation. Detection of TNT was achieved from the measuring of quenching PL of poly(tetraphenylsilole) siloxane nanoaggregates by adding the TNT. A linear Stern?Volmer relationship was observed for the detection of TNT. This research was supported by Agency for Defense Development. This work was supported by the Human Resource Training Program for Regional Innovation through the Ministry of Education and National Research Foundation of Korea (NRF-2012H1B8A2026282)
