Quantum coherence governs macroscopic polymorphism in organic semiconductors

The Takeaway
This discovery suggests that large organic molecules can maintain their quantum behavior over distances much larger than previously thought possible. This allows them to self-assemble into massive macroscopic structures using quantum interference rather than standard chemical bonding.
From the abstract
The wave-particle duality of massive macromolecules -- such as the fullerene C$_{60}$ -- is a well-established quantum phenomenon. However, whether the quantum behavior of large organic molecules actively dictates the macroscopic structure and function of synthetic materials remains unknown. In organic semiconductors, crystal polymorphism fundamentally determines optoelectronic performance, yet classical thermodynamic models consistently fail to resolve the microscopic origins of phase selection
