以前，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。为了获得具有生物竞争性的绿色/黄色NAT荧光团，设计并合成了一类新的4-酮基-2-（40-N，N-二苯基）-苯基三唑类化合物.在此，我们提出了我们的研究，这些新的荧光团表现出优异的发光发射在溶液中（U高达96%）和在固态（U高达43%）。此外，这些新化合物还具有聚集诱导发光（AIE）和可逆的机械致变色发光性质，这预示着它们在化学和材料科学中的潜在应用。
Previously, we reported 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-(40-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 (U up to 96%) and in the solid state (U up to 43%). Furthermore, these new compounds showed aggregationinduced emission (AIE) properties and reversible mechanochromic luminescence properties, which suggested their potential applications in chemical and materials science.
