准一维有机量子阱特征
Organic quantum-well characteristics of quasi-one-dimensional copolymers
【摘要】 有机聚合物Oligomers(低聚体 )可以共聚形成所谓的共聚物 ,具有准一维量子阱或超晶格结构特征。本文针对聚乙炔 (polyacetylene) (PA)和聚对苯撑 (poly(p phenylene) ) (PPP)组成的三嵌段 (tri block)共聚物xPA/nPPP/yPA的量子阱性质进行了研究 ,发现均聚物组份及其界面耦合对共聚物的电子态具有调制作用。
【Abstract】 Copolymers,synthesized by oligomers or homopolymers have quasi one dimensional structures. A tight binding model was suggested to study the organic quantum well properties of triblock copolymer x PPP/ n PA/ y PPP consisting of polyacetylene(PA) and poly ( p phenylene)(PPP). It was found that the electronic density in the lowest conductive state(LUMO) could be tuned by the ratios of homopolymers and interfacial coupling.
