A novel small molecule consisting of triple bond-bridged naphthalene-anthracene core was synthesized with either a pentyl or decyl end group. The linear and planar shape of naphthalene-anthracene core allowed herringbone packing pattern with enhanced conjugation length and close molecular packing structure. The film morphology of naphthalene-anthracene based small molecules was also affected by the
合成了由三键桥联萘-蒽核组成的新型小分子,其带有戊基或癸基端基。萘-蒽核的线性和平面形状使人字形堆积图案具有增强的共轭长度和紧密的分子堆积结构。萘-蒽基小分子的膜形态也受到戊基和癸基的影响。与癸基取代的实例相比,戊基取代的分子表现出更统一和有序的堆积模式,癸基取代的实例表现出至少两个多晶型物。通过有机场效应晶体管的测量来表征两个新分子的p型半导体特性。在80°C的退火设备中,戊基类似物的场效应迁移率为0.045 cm 2/(V∙s),约为癸基取代化合物的3倍。
