In article number 1808300 , Daisuke Yokoyama, Hisahiro Sasabe, Junji Kido, and co‐workers demonstrate control over the molecular aggregation state in organic semiconductor films during vapor deposition. Synergetic effects of disordered hydrogen bonds and planar anisotropic molecular shapes enhance the horizontal molecular orientation and significantly increase the electron mobility. Moreover, the molecular engineering methodology delivers a highly efficient and stable organic optoelectronic device.
