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(τ_(1/2))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.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(τ_(1/2))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.
