that N-2-aryl triazoles (NATs) exhibited good fluorescence activity in the UV/blue light range. In an effort to achieve biocompetitive NAT fluorophores with green/yellow emission, a new class of 4-keto-2-(4′-N,N-diphenyl)-phenyl triazoles were designed and synthesized. Herein, we present our study on these novel fluorophores which demonstrated excellent luminescence emission both in solution (Φ up to
此前,我们报道了N -2-芳基三唑(NAT)在紫外/蓝光范围内表现出良好的荧光活性。为了实现具有绿色/黄色发射的生物竞争性 NAT 荧光团,设计并合成了一类新型 4-keto-2-(4'- N , N -dipheny)-苯基三唑。在此,我们介绍了对这些新型荧光团的研究,这些荧光团在溶液中(Φ高达 96%)和固态(Φ高达 43%)都表现出出色的发光发射。此外,这些新化合物表现出聚集诱导发射(AIE)特性和可逆力致变色发光特性,这表明它们在化学和材料科学中的潜在应用。
