A series of pi-conjugated compounds ending with dibenzosuberenylidene were synthesized efficiently. Their luminescence efficiencies were well-tuned by structural modification. Moreover, relative emission intensities were strongly affected by their existing appearances and exhibited aggregation-induced emission (AIE) behavior. Thus, emissions from nanoparticles, films, or powders were found to be more efficient than those from solutions. It demonstrated that these synthesized compounds might be practically used as fluorescent materials for potential optoelectronic applications.
高效合成了一系列以二苯并亚芴基结尾的π共轭化合物。通过结构修饰对其发光效率进行了良好的调控。此外，相对发射强度受其存在形态的强烈影响，并表现出聚集诱导发光（AIE）行为。因此，发现纳米颗粒、薄膜或粉末的发射比溶液中的发射更有效。这表明这些合成化合物可能实际用作潜在光电子应用的荧光材料。
