Abstract

The realization of robust luminescence in crystalline and anisotropic nanowires of wide bandgap light-emitting conjugated polymers (LCPs) is challenging. Compared to the periodic arrangements in conventional crystalline nanostructure, hierarchical uniform structures will provide an electronic landscape to obtain excellent optoelectronic behaviors, which are desirable for polymer light-emitting diodes (PLEDs) and polymer lasers. Here, we construct a range of robust hierarchical uniform crystalline nanowires of wide bandgap polydiarylfluorenes for light-emitting optoelectronic applications. Steric hindrance interactions of the bulky groups enable these nanowires to show a robust deep-blue emis..
