Abstract
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-(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 96%) and in the solid state (Φ up to 43%). Furthermore, these new compounds showed aggregation-induced emission (AIE) properties and reversible mechanochromic luminescence properties, which suggested their potential applications in chemical and materials science.
摘要
此前，我们报道了N-2-芳基三唑（NATs）在紫外/蓝光范围内表现出良好的荧光活性。为了获得具有绿色/黄色发射的生物竞争性NAT荧光团，设计并合成了一类新型的4-酮-2-(4'-N,N-二苯基)-苯基三唑。在此，我们展示了对这些新型荧光团的研究，其在溶液中（Φ高达96%）和固态中（Φ高达43%）均表现出优异的发光发射。此外，这些新化合物表现出聚集诱导发光（AIE）特性和可逆的机械变色发光特性，这表明它们在化学和材料科学中的潜在应用。
