Perylene derivatives are excellent n-type dyes that display superior potential in optical and electronic materials. Significant efforts have been endeavored toward structural modification of the perylene skeleton. Herein, we showed that the simple coordinating self-assembly of perylenetetracarboxylate could already generate excellent one-dimensional perylene-based self-assembly, and its structural details could be simply tailored by concentration. Microbelts with high potential energy are formed at concentrations below 1 mM, whereas nanobelts with low potential energy appear at higher concentrations. The coordination stoichiometry was 1 : 1 in the microbelt and 1 : 2 in the nanobelt, which resulted in drastic material properties, such that the microbelt with 1 : 1 coordinated PTC and Ni2+ displayed a conductivity 80 times that of the 1 : 2 coordinated nanobelt, whereas the latter exhibited 4 times higher specific surface area, significant fluorescence, and polarized light transmittance. These findings not only unveil a scenario of the coordinating self-assembly of perylenetetracarboxylate, but also show that concentration can act as a powerful tool to tailor the function of self-assembled materials.

carboxy四羧酸盐的量身定制自组装组成和配位自组装的功能

ylene衍生物是出色的n型染料,在光学和电子材料中显示出优异的潜力。已努力进行the骨架的结构改性。在本文中,我们表明per四羧酸酯的简单配位自组装已经可以产生出色的基于dimensional的一维自组装,并且其结构细节可以通过浓度简单地定制。低于1 mM的浓度会形成具有高势能的微带,而处于较高浓度的则会出现具有低势能的微带。协调的化学计量为1   1中的microbelt和1   2的纳米带,这导致激烈的材料性质,使得与1 microbelt   1配位的PTC和Ni 2+的电导率是1   2配位的纳米带的80倍,而后者的比表面积高4倍,具有显着的荧光和偏振光透射率。这些发现不仅揭示了tetra四羧酸盐自组装的配位方案,而且还表明浓度可以作为调整自组装材​​料功能的有力工具。
