二维自组装已经在具有扭曲发色团的苝酰亚胺中得到证实，其中π-π堆叠单元通过氢键相互作用相互连接。光谱测量和理论计算表明，在组装弱J型激子耦合。二维晶体的高光电导性使其成为进一步光电应用的有希望的候选者。
2D self-assembly has been demonstrated in perylenediimides with twisted chromophores, in which the π-π stacked units are interconnected via hydrogen bonding interactions. Spectroscopic measurements and theoretical calculations suggest a weak J-type exciton coupling in the assembly. High photoconductivity of the 2D crystal makes it a promising candidate for further opto-electronic applications.
