Abstract
Precisely controlled organic one-dimensional (1D) and two-dimensional (2D) materials with unique optoelectronic properties have attracted wide interests. By the introduction of chlorine into the poly(p-phenylenevinylene) (PPV) core, we produced a series of 1D rod-like micelles, whose sizes were controlled by the concentrations of solutions, using self-assembly (SA) of conjugated copolymers (PPV-Cl20%)10-b-P2VP20. The transformation from 1D rod-like micelles to 2D uniform diamond-like micelles was achieved by the thermally induced nucleation SA. The sizes of the 2D diamond-like micelles could be tuned by the annealing temperature and the ratio of unimer to seed. It is demonstrated that the morphology transformation from rod-like micelles to diamond-like micelles was based on energetics including thermodynamic and kinetic points.
