摘　　要：以4-甲酰苯硼酸与邻苯二胺衍生物为原料合成了3个4-（2,3-二氢-1H-1,3,2-苯并二唑硼烷）-苯甲醛衍生物。其中,标题化合物与氨和脂肪族胺发生相互作用后,荧光发射强度增强,且最大发射峰红移至380 nm。将标题化合物沉淀在滤纸上制备检测试纸,试纸在紫外灯照射下不发光,润湿后暴露在氨气环境中可以发出肉眼可见的紫红色荧光,可用于快速检测氨气。经1HNMR、IR、UV表征手段证实了探针化合物与氨气和脂肪族胺间的相互作用为醛基与氨基间的弱相互作用。Three derivatives of 4-（2,3-dihydro-1H-1,3,2-benzodiazole）-benzaldehyde were obtained by reacting 4-formylphenylboronic acid with o-phenylenediamine and its derivatives.When 4-（2,3-dihydro-1 H-1,3,2-benzodiazole）-benzaldehyde interacts with ammonia and aliphatic amines,the fluorescence intensity increased and the maximum emission of the fluorescence emission spectrum shows a red-shifted to 380 nm.What＇s more,the solution of the 4-（2,3-dihydro-1H-1,3,2-benzodiazole）-benzaldehyde was dropped on filter paper to provide a test paper of ammonia detection,which displayed non-emissive and became strong violetred fluorescence emission after exposure to ammonia vapor.Therefore,4-（2,3-dihydro-1 H-1,3,2-benzodiazole）-benzaldehyde can be used for rapid detection of ammonia.The1 HNMR,IR and UV spectra confirmed that the interaction between the probe and ammonia or aliphatic amines was weak interaction of the aldehyde group and the amino group.
