END-SUBSTITUTED HETEROACENES WITH PAIRWISE COUPLING IN CRYSTALLINE FORM FOR PURE SPIN POLARIZATION AND OPTICAL READOUT

Abstract: the present disclosure concerns crystalline pairs of triethylsilyl-ethynyl tetraceno[2,3-b]thiophene and derivatives thereof. the crystallized pairs generate and maintain a high degree of spin polarization that constitutes a qubit. in some aspects, end substitution of a heterocyclic ring with a silicon-based group enforces the necessary pairwise interaction, with larger intermolecular distances between pairs in the crystal that can then produce a parallel alignment of the magnetic axes of all molecules within the crystal unit cell. in addition, end substitution provide energy level alignment between a triplet pair and the emissive singlet state which then allows for low temperature emission from the triplet pair.
