摘要：

2D self-assembly has been demonstrated in perylenediimides with twisted chromophores, in which the pi-pi 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.
