菲的三个同分异构呋喃类似物,包括苯并[1,2- b ; 6,5- b ']二呋喃(3O),苯并[1,2- b ; 4,3- b ']二呋喃(4O)和苯并[制备了1,2- b ; 3,4- b ']二呋喃(5O),并对其性能进行了系统的研究。与苯并[1,2- b ; 4,5- b ']二呋喃(1O)和苯并[1,2- b ; 5,4- b ']二呋喃(2O)相比,荧光量子有明显差异。3O-5O的产量。考虑吸收和荧光光谱,循环伏安图和B3LYP / 6-31G(d,p)计算表明,在本研究中制备的所有化合物中,4O具有最高的给电子/受电子特性。5O的较低的供电子/受电子性能是由于其π共轭体系的链长较短。3O出乎意料的高给电子性和低电子接受性分别归因于自由基阳离子和阴离子状态的变化。3O-5O的噻吩和硒烯类似物的最高占据和最低未占据分子轨道的能级 还计算了它们的相对能量,并以类似方式解释了它们的相对能量。
