These are preliminary reports that have not been peer-reviewed. They should not be regarded as conclusive, guide clinical practice/health-related behavior, or be reported in news media as established information. For more information, please see our FAQs.
Preprints are manuscripts made publicly available before they have been submitted for formal peer review and publication. They might contain new research findings or data. Preprints can be a draft or final version of an author's research but must not have been accepted for publication at the time of submission.

design, synthesis, properties, and performance of a new class of promesogenic calamitic
side-tethering organic ligands used to direct quantum dot nanoparticle
self-assembly via nematic templating are described. This work was motivated by inadequate
modularity, step count, and yield associated with syntheses of existing
ligands. Attaching the new ligands to quantum dots and dispersing them in a
liquid crystal host affords hollow micron-sized capsules via nematic templating.
The capsules resist thermal decomposition up to 350 °C — significantly higher than any previously
reported microcapsules assembled from side-tethering calamitic
ligand-functionalized nanoparticle. Evaluation of the capsules by small-angle X-ray scattering shows that interparticle
spacing varies from 10–13 nm depending on the ligand used, and is correlated to
aminoalkyl chain length.
