optoelectronics. Three block copolymer model compounds were made by first synthesizing 5-ethynyl-2,2′:5′,2″-terthiophene, 5-(2-propynyl)-2,2′:5′,2″-terthiophene and 5-(3-butynyl)-2,2′:5′,2″-terthiophene and then performing hydroboration polymerization from the alkyne of the terthiophene. The impact of the connectivity between the polymer blocks of these compounds was investigated. Theoretical and experimental
共轭嵌段共聚物代表了一类在电子和光电子领域具有潜在应用的材料。通过首先合成5-乙炔基-2,2':5',2''-对噻吩,5-(2-丙炔基)-2,2':5',2''-对噻吩和5-合成三嵌段共聚物模型化合物(3-丁炔基)-2,2':5',2''-对噻吩,然后从对噻吩的炔烃进行硼氢化反应。研究了这些化合物的聚合物嵌段之间的连接性的影响。理论和实验研究表明,电荷转移发生在全共轭共聚物模型化合物中,并且电子耦合随着n型和p型材料之间连接桥长度的增加而降低。
