We report herein a new triptycene derivative (1) with an azo functional group. This molecule has been used as a monomer to yield two linear polymers (TAFPs) that have several triptycene units dangling from the linear polymer chain. TAFPs are soluble in organic solvents and are thermally stable. TAFPs can be cast into thin films. Further, these polymers are fluorescent with emission intensity increasing upon irradiation with ultraviolet light due to photoisomerization of the azo groups present in them. The fluorescence of TAFPs are quenched in the presence of C₆₀, which supports their strong affinity for each other. Since both TAFP1 and TAFP2 form stable thin films of uniform thickness over large area coupled with their interaction with C₆₀, these polymers may find potential applications in the development of optoelectronic devices or as molecular sensors in supramolecular chemistry.

具有悬空三苯乙烯单元的光响应聚合物作为富勒烯-C60 的有效受体

我们在此报告了一种具有偶氮官能团的新三萜衍生物 ( 1 )。该分子已被用作单体以产生两种线性聚合物 ( TAFP )，这些聚合物具有几个悬挂在线性聚合物链上的三苯乙烯单元。TAFPs可溶于有机溶剂并且是热稳定的。TAFP可以浇铸成薄膜。此外，由于存在于其中的偶氮基团的光异构化，这些聚合物在用紫外光照射时具有发射强度增加的荧光。TAFPs的荧光在 C ₆₀的存在下被淬灭，这支持它们彼此之间的强亲和力。由于TAFP1和TAFP2在大面积上形成均匀厚度的稳定薄膜，再加上它们与 C ₆₀的相互作用，这些聚合物可能会在光电器件的开发或作为超分子化学中的分子传感器中找到潜在的应用。
