A solid fluorescent material composited with carbazole-based fluorescent probe and silica aerogel was prepared for the detection of formaldehyde.A new type of fluorescent probe was designed and synthesized.By effectively grafting the probe molecules on the silica gel,a silica aerogel loaded with fluorescent probes with high porosity and high specific surface area was prepared.The composite material not only can avoid the fluorescence quenching caused by the aggregation of the probe molecules,but also had a high sensitivity for the recognition of formaldehyde,and can detect a minimum formaldehyde concentration of 10-5mol/L.
