A facile and convenient fluorescence detection of gamma-ray radiation is reported. This is based on the ensemble of silole 1and polymer 2, by taking advantages of AIE (aggregation-induced emission) behavior of silole compounds and the fact that polymers with –SO2groups in the main chain can be degraded upon gamma-ray radiation. The fluorescence intensity of the ensemble of silole 1and polymer 2decreases gradually after exposure to increasing dose of gamma-ray radiation. The detection of gamma-ray radiation with silole 1and polymer 2can be performed at ambient conditions and gamma-ray radiation as low as 0.13 kGy dose can be successfully detected.
