The “kinked” shapes of conjugated alkadiynes constrain chain packing in monolayers on HOPG. Centrally located diyne units permit assembly of 1,5-bis(alkadiyne)anthracene monolayers. Off-center diynes inhibit self-assembly. Shape matched pairs of off-center diyne chains direct self-assembly of compositionally patterned, two component monolayers.
“扭曲”的共轭二炔形状限制了单层在高取向热解石墨(HOPG)上的链堆积。中心定位的二炔单元允许1,5-二(炔基)蒽单层的组装。偏心的二炔抑制自组装。形状匹配的偏心二炔链引导组成模式化的双组分单层自组装。
