TL;DR: Design of highly efficient phosphorescent emitters based on metal- and heavy atom-free boron compounds has been demonstrated by taking advantage of the singlet fission process.
Abstract: Design of highly efficient phosphorescent emitters based on metal- and heavy atom-free boron compounds has been demonstrated by taking advantage of the singlet fission process. The combination of a suitable molecular scaffold and appropriate electronic nature of the substituents has been utilized to tailor the phosphorescence emission properties in solution, neat solid, and in doped PMMA thin films.

TL;DR: In the title molecule, C21H20ClF2NO2, the piperidine ring adopts a slightly-distorted boat conformation, the two benzene rings form a dihedral angle of 87.43 (1)° and a weak intramolecular C—H⋯π interaction is observed.
Abstract: In the title molecule, C21H20ClF2NO2, the piperidine ring adopts a slightly distorted boat conformation. The two benzene rings form a dihedral angle of 87.43 (1)°. A weak intramolecular C—H⋯π interaction is observed. In the crystal, weak C—H⋯O hydrogen bonds and weak C—H⋯π interactions connect the molecules, forming a three-dimensional network.

TL;DR: In the title molecule, C27H30N4O2S·C3H7NO, the fused piperidine and cyclohexane rings adopt a twin chair conformation and the phenyl groups occupy equatorial sites and the dimethylformamide solvent molecule is connected to the main molecule by an N—H⋯O hydrogen bond.
Abstract: In the title molecule, C27H30N4O2S·C3H7NO, the fused piperidine and cyclohexane rings adopt a twin chair conformation and the phenyl groups occupy equatorial sites. The phenyl rings make a dihedral angle of 40.74 (2)°. In the crystal, the dimethylformamide solvent molecule is connected to the main molecule by an N—H⋯O hydrogen bond. An additional N—H⋯O hydrogen bond connects molecules into chains along [100]. Pairs of weak C—H⋯O hydrogen bonds connect inversion-related chains. The ethyl group was refined as disordered over two sets of sites with an occupancy ratio of 0.660 (17):0.340 (17).
