Abstract

The fabrication of large-scale unidirectionally aligned organic crystalline ribbons is a great challenge. Here, we developed a limited solvent vapor-assisted crystallization (LSVC) method. By adopting an up-side-down funnel, single crystalline microribbons of C₈-BTBT with uniform alignment were easily prepared on different substrates, indicating the feasibility of the LSVC method.
