Self-assembly of conjugated polymers offers a powerful method to prepare semiconducting two-dimensional (2D) nanosheets for optoelectronic applications. However, due the typical biaxial growth behavior polymer self-assembly, independent control width and length 2D sheets has been challenging. Herein, we present greatly accelerated crystallization-driven self-assembly (CDSA) system polyacetylene-based produce nanorectangles with precisely controllable dimensions. In detail, rectangular seeds tunable widths 0.2-1.3
