However, the effects of ring fusion and furan substitution on the optoelectrical properties of oligothiophenes are still unclear. In this study, based on popular pentathiophene, eight molecules including three ring-fused and five furan-substituted derivatives are systematically designed, and their frontier molecular orbitals, dipole moments, planarity, exciton binding energy (<i>E</i>_b), singlet-triplet energy differences, and fluorescence quantum yields are calculated. The computed data demonstrate that full-ring fusion and two- and more-furan substitutions can greatly enhance the fluorescence quantum yields. Five potential molecules with about 100% of fluorescence quantum yield, i.e., TTTTT, SOSOS, OSOSO, SOOOS, and OOOOO, are screened. The results show that to obtain high fluorescence quantum yield, high <i>E</i>_b is required, and the flexible torsional displacement during the excitation from ground to the first excited state should be removed as much as possible.

Extensive use of geminals in wavefunctions has been limited by their high cost stemming from the many combinations of the two-electron basis functions (orbital pairs) used to build the geminals. When evaluating the overlap of the APG wavefunction with an orthogonal Slater determinant, this cost can be interpreted as the cost of evaluating the permanent, resulting from the symmetry with respect to the interchange of orbital pairs, and the cost of assigning the occupied orbitals to the orbital pairs of the wavefunction. Focusing on the latter, we present a graphical interpretation of the Slater determinant and utilize the maximum weighted matching algorithm to estimate the combination of orbital pairs with the largest contribution to the overlap.
