A series of six compounds composed of an emissive oligofluorene or dithiophenethiobenzimidazole (p3) core bearing H-bonding biuret molecular recognition motifs in the meta- or para-position was investigated with regard to their propensity to undergo either social or narcissistic self-sorting when deposited from dilute THF solutions. The structural similarity of the compounds uniformly leads to social self-sorting with the exception of two combinations involving p3 for which narcissistic self-sorting is observed instead. Their behavior is attributed to the difference in location of the biuret groups (meta vs. para) combined with a greater structural difference in the conjugated core. Deposition of solutions demonstrating narcissistic self sorting gives rise to ensembles of disk-like aggregates exhibiting two different populations of emission (blue and magenta or yellow and orange).

自发自选超分子相互作用的结合，用于自发制造用于OLED应用的多色固态材料

一系列的发射低聚芴或dithiophenethiobenzimidazole（组成六种化合物的P3）芯轴承氢键缩二脲分子识别基序在间位-或对位就其倾向位上进行了研究，以经受社会或自恋排序沉积时从稀THF溶液中提取。这些化合物的结构相似性一致地导致了社会自我选择，只有两个涉及p3的组合例外，而观察到的是自恋自我分类。它们的行为归因于缩二脲组位置的差异（元与对位）与共轭核心中更大的结构差异结合在一起。表现出自恋自我分选的溶液的沉积产生了呈盘状聚集体的集合体，这些聚集体表现出两种不同的发射种群（蓝色和品红色或黄色和橙色）。
