High performance oxygen-bridged N-shaped semiconductors with a stabilized crystal phase and blue luminescence

Here, we describe an oxygen-bridged N-shaped π-electron core, dinaphtho[2,3- d :2′,3′- d ′]benzo[1,2- b :4,5- b ′]difuran ( DNBDF ), as a new entity of organic semiconducting materials. Interestingly, by introduction of flexible alkyl chains at appropriate positions, DNBDF π-cores exhibit solution processability, a highly stabilized crystal phase, high mobility, and blue luminescence as a solid.
