摘要:

设计合成了一系列萘并吡喃-四苯乙烯稠合化合物(NP1~NP5), 并研究了其光致变色及荧光性质. 与萘并吡喃母体化合物NP0相比, 化合物NP5的褪色速率显著提高, 其褪色半衰期(τ1/2)达到0.75 min. 该类化合物还具有光响应迅速及耐疲劳性好等优点. 此外, 化合物NP2的四氢呋喃溶液的荧光性质可通过紫外光照调控, 即在360 nm紫外光光照前具有荧光性质, 光照后荧光性质消失, 但并无聚集诱导发光现象.

Abstract:

A novel class of naphthopyran-tetraphenylethylene hybrids NP1—NP5 were designed and synthesized, and their photochromic and fluorescent properties were investigated in detail. Compared to 2,2-diphenyl-2H-benzo[h]chromene(NP0), the thermal fading rate of NP5 has significantly improved with the fastest half-time(τ1/2) of 0.75 min. Such kind of compounds also exhibited fast photo-responsive speed and excellent fatigue resistance. In addition, the tetrahydrofuran solution of NP2 is fluorescent, which can be quenched by an irradiation with 360 nm UV light. However, no aggregation-induced emission was observed for these compounds.

Key words: Photo-functional material, Naphthopyran, Aggregation-induced emission
