“…The trimer of sulfonate-containing fluorene and thiophene units keeps almost linear, the trimer of sulfonate-containing fluorene and alkyl chain-containing carbazole tilts a bit, while the trimer of sulfonate-containing fluorene and 9,9-dioctyl fluorene presents a spiral agglomeration with alkyl chains stretching inward. It reasonably concludes that STF's polymer chain has high conjugation and SCF's chain is more flexible, in agreement with the reports that bulkier alkyl substituted carbazole monomer hinders the coplanarity and intramolecular conjugation, [27,28] and thiophene units increase the conjugation. [27,29] By contrast, SPF's polymer chain is prone to agglomerate.…”

Three sulfonate‐containing polyelectrolytes are elaborately designed and used to passivate perovskite film with the anti‐solvent method. Under the influence of the secondary monomer, three copolymers present various chemical configurations and deliver different modification effects. Fluorene‐thiophene copolymer STF has linear and highly‐conjugated chain. STF‐perovskite film presents large crystal grains. Fluorene‐carbazole copolymer SCF has flexible chain and easily enters into grain boundary areas. SCF‐perovskite film is homogenous and continuous. Fluorene‐fluorene copolymer SPF agglomerates on the surface and is not applicable to the anti‐solvent method. The full investigation demonstrates that STF and SCF not only conduct surface defect passivation, but also improve the film quality by being involved in the perovskite's crystallization process. Compared with the control device, the devices with STF and SCF deliver high efficiency and excellent stability. The unencapsulated devices with STF and SCT maintain ≈80% of the initial power conversion efficiency (PCE) after 40 days of storage under 30–40% relative humidity. SCF performs better and the device maintains 60% of the initial PCE after 20 days of storage under 60–80% relative humidity.

“…Adamantane is a wide band gap material that has been used for host materials in blue organic light-emitting diodes (OLEDs) as an efficient π-conjugation interrupter [153]. The adamantane derivatives exhibit high triplet energy, which makes them suitable as a host material for highly efficient blue OLED devices [24,[154][155][156]. A report on adamantane-based host materials, 2,2-bis(4-carbazolyl-9-ylphenyl)adamantane (Ad-Cz), was first published by Fukagawa et al [154].…”

Diamondoids are cage-like hydrocarbon materials with unique characteristics such as low dielectric constants, negative electron affinity, large steric bulk, and electron-donating ability. They are widely used for advanced functional materials in nanocomposite science. Surface modification of diamondoids also produces functional derivatives that broaden its applications. This article provides a concise review of the fundamentals of diamondoids, including their origin and functionalization, electronic structure, optical properties, and vibrational characteristics. The recent advances of diamondoids and their derivatives in applications, such as nanocomposites and thin film coatings, are presented. The fabrication of diamondoid-based nanostructured devices, including electron emitters, catalyst sensors, and light-emitting diodes, are also reviewed. Finally, the future developments of this unique class of hydrocarbon materials in producing a novel nanostructure system using advanced nanotechnologies are discussed. This review is intended to provide a basic understanding of diamondoid properties, discuss the recent progress of its modifications and functionalization, and highlight its novel applications and future prospects.
