The molecular structures of Y6 (a) and the additive (b). Conventional vapor- and liquid-phase growth methods prove ineffective for Y6 and Y6-like NFA due to their low decomposition temperatures and steric hindrance from long side chains. By employing an additive, a cocrystal is grown successfully through the establishment of novel configuration coupling interactions, enabling the growth of high-quality organic single crystals (c).
