Abstract |
In order to grasp the kinetically controlled polymorphic superstructures from asymmetric supramolecules, a pyrene-attached asymmetric supramolecule (abbreviated as Py3M) was newly synthesized. Superstructures of Py3M exhibited the monotropic phase transition between a stable crystalline phase (K1) and a metastable crystalline phase (K2). Py3M formed two synclinically tilted crystalline superstructures: the 6.75 nm and 4.30 nm periodicities of layered structures for K1 and K2 phases, respectively. The stable K1 phase and metastable K2 were predominantly induced by the π-π interactions and hydrogen-bonds. UV-Vis and PL experiments indicated that the photo-physical properties of Py3M were directly related with their molecular packing superstructures. This work was mainly supported by Mid-Career Researcher Program (2016R1A2B2011041), BK21 Plus program, Korea, and BRL (2015042417) of Korea. |
