cells, a uniform arrangement and a faceon morphology orientation of the active layer facilitate a high power-conversion efficiency. [1b,c] Additionally, organic luminescent materials with polymorphism exhibit distinct and occasionally completely different photophysical properties depending on the molecular packing. [1d,f ] Therefore, it would be ideal if the molecular packing could be partially controlled at the molecular design stage, notwithstanding the significant challenge this presents. Recently, we reported that the ignorable difference of substituents could effectively influence the molecular packing and the corresponding properties, which could be termed as one of molecular uniting set identified characteristic (MUSIC), indicating that it is really possible to control the molecular packing at the stage of molecular design with the good utilization of the electronic effect. [2] As the steric effect generally accompanies the electronic effect, it may be utilized for the adjustment of molecular packing. [3] Therefore, one may perceive that the introduction of bulky groups to aromatics will complicate the formation of aggregated dimers because of the enlarged intermolecular dis
