通过菲的Friedel-Craft芳基化反应(聚合物B型)或9，10-二(氯甲基)菲与适时的芳香族底物缩合反应(聚合物A型)，合成了许多在高分子链上含有芳基和芳基的交替共聚物。A型聚合物均含有9，10-二取代菲单元，而B型聚合物含有1，4-二取代菲单元。通过它们的核磁共振和紫外光谱，并与合适的模型化合物进行类比，确定了聚合物的结构。研究发现，与只含有芳基单元的聚苄基相比，在聚合物链中包含菲单元会产生更高的熔点和更多的可溶性物质。在聚合物中还引入了一些有趣的荧光特征，在约440mμ处显示出强烈的发射。
A number of alternating copolymers containing anthryl and aryl units in the polymer chain have been prepared by Friedel-Crafts arylation of the anthracene (polymer type B) or by condensation of 9,10-bis(chloromethyl) anthracene with opportune aromatic substrates (polymer type A). Polymers of type A were all found to contain 9,10-disubstituted anthracene units, but polymers of type B were found to contain 1,4-disubstituted anthracene units. Structure of the polymers were established through their NMR and ultraviolet spectra, and through analogy with appropriate model compounds. It has been found that the inclusion of anthracene units in the polymer chain yields higher melting and more soluble materials with respect to polybenzyls containing only aryl units. Anthracene units introduce, also, some interesting fluorescence characteristics in the polymers, which show intense emission at about 440 mμ.
