  reveal that the twist between adjacent pentiptycene units in OPEs is a consequence of the electronic rather than steric effects of iptycenyl substituents. The electronic effect of iptycenyl substituents is manifested in decreased phenylene π polarizability as the net effect of both electron‐donating hyperconjugation and an electron‐withdrawing inductive effect.

  寡骨干平面的依赖性（p取代基的内在电子特性和溶剂性质的（苯基亚乙炔基）（OPEs）已通过一系列中心对称的五环体系戊基戊烯-戊二烯基-芳烃-戊基戊烯基-戊基戊烯进行了实验证明中央芳烃上的取代基。在冷冻的2-甲基四氢呋喃（MTHF）中，当取代基是吸电子的（F和酰胺基）时，相邻的戊烯并茂单元倾向于相互扭曲，从而形成TPPT或TTTT构象，而平面化的PPPP主链则更适合给电子取代基（烷基和烷氧基）的情况。通常，通过用甲基环己烷或乙醇/甲醇混合溶剂代替MTHF，可以提高采用PPPP形式的可能性。这些观察结果表明，在OPE中相邻的戊烯并茂单元之间的扭曲是烯丙基烯基取代基的电子效应而不是空间效应的结果。噻吩基取代基的电子效应表现为亚苯基π极化率的降低，这是给电子超共轭和吸电子诱导效应的净效应。可变温度电子吸收光谱和光谱学是这项工作的关键工具。我们的发现为OPE的构象和电子工程以及新型基于iptycene

  The present invention relates to a class of luminescent and conductive polymer compositions having chromophores, and particularly solid films of these compositions exhibiting increased luminescent lifetimes, quantum yields and amplified emissions. These desirable properties can be provided through polymers having rigid groups designed to prevent polymer reorganization, aggregation or &pgr;-stacking upon solidification. These polymers can also display an unusually high stability with respect to solvent and heat exposures. The invention also relates to a sensor and a method for sensing an analyte through the luminescent and conductive properties of these polymers. Analytes can be sensed by activation of a chromophore at a polymer surface. Analytes include aromatics, phosphate ester groups and in particular explosives and chemical warfare agents in a gaseous state. The present invention also relates to devices and methods for amplifying emissions by incorporating a polymer having an energy migration pathway and/or providing the polymer as a block co-polymer or as a multi-layer.
