Paper Abstract

The uncertainty evolution of conformation and molecular packing from solution to film is key challenge for the repeatability of procedures in organic optoelectronics. Herein, we observed the noncovalent force at the bulky groups to decode the supramolecular steric hindrance (SSH) effect and to propose synergistically molecular attractor-repulsor theory (SMART). The fine difference between ideal and real bulks were described and the SSH effect have been proved by two comparable stat-of-the-art models. The SMART design guide us to discover blue oligo/polydiarylfluorenes with beta phase as well as nanosheets with the paradigm of Interdigital Lipid Bilayer-like (ILB) mode. SMART address one kind of AR molecules with potential controllable behaviors. The design of bulk-withdraw and bulk-rich will exhibit the unreplaceable role in morphology-directed design that is just like the role of donor-acceptor molecular design of organic polymer semiconductors.
