Superprotonic Conductivity of Guanidinium Organosulfonate Hydrogen-Bonded Organic Frameworks with Nanotube-Shaped Proton Transport Channels.

Grasping proton transport pathways and mechanisms is vital for the application of fuel cell technology. Herein, we screened four guanidinium organosulfonate charge-assisted hydrogen-bonded organic frameworks (HOFs), namely, , , , and , which possess high hydrogen-bonded density proton transport networks shaped like nanotubes. These materials were prepared by self-assembly through charge-assisted interactions between guanidinium cations and organosulfonate anions, as well as by host-guest regulation.

Ionic Hydrogen-Bonded Organic Frameworks with a Two-Photon Synergistic Color Change and Their Information Encryption Applications.

Photochromic hydrogen-bonded organic frameworks (HOFs) can introduce different luminescent functional groups to achieve synergistic controlled multiple color change properties, which are in great demand for diverse information encryption applications. We report in this paper switchable photochromic and photoluminescent dual luminescent functional group HOFs constructed with synergistic effects by ,'-bis(2-phenylalanine)-1,4,5,8-naphthalenediimine (HPheNDI) and benzenecarboximidamide 4,4'-azobis(hydrochloride) (AZBH). The crystal powder of is orange-red in color, which can be changed to black under the irradiation of a 365 nm ultraviolet (UV) light source for 15 min.

Patient-caregiver dyad concordance of transition readiness assessment for adolescent with cancer: A network analysis.

Aims: The concordance of adolescents with cancer and caregivers was examined, and the core elements of transition readiness were identified.

Methods: In this cross-sectional study, 196 adolescent-caregiver dyads completed the Chinese version of Self-Management and Transition to Adulthood with Rx = Treatment Questionnaire and its parent version between March 2023 and August 2023. Intraclass correlation coefficients, paired t-tests and network analysis were used for data analysis.

Transition readiness of adolescents with cancer: A cross-sectional study based on self-determination theory.

Purpose: This study aimed to assess the transition readiness of adolescents with cancer in central China and to explore the paths associated with transition readiness based on self-determination theory (SDT).

Methods: Self-management and transition to adulthood with Rx = treatment questionnaire, patient activation measure, perceived social support scale and general self-efficacy scale were used to measure transition readiness as well as constructs pertaining to SDT (competence, relatedness and autonomy). The factors influencing transition readiness were evaluated using multiple linear regression.

Charge-Assisted Ionic Hydrogen-Bonded Organic Frameworks: Designable and Stabilized Multifunctional Materials.

Hydrogen-bonded organic frameworks (HOFs) are a class of crystalline framework materials assembled by hydrogen bonds. HOFs have the advantages of high crystallinity, mild reaction conditions, good solution processability, and reproducibility. Coupled with the reversibility and flexibility of hydrogen bonds, HOFs can be assembled into a wide diversity of crystalline structures.

Water-Induced Single-Crystal to Single-Crystal Transformation of Ionic Hydrogen-Bonded Organic Frameworks with Enhanced Proton Conductivity.

Two ionic hydrogen-bonded organic frameworks (iHOF-10, iHOF-11) were prepared using 1,1'-diamino-4,4'-bipyridine diiodide (Dbpy ⋅ 2I) and tetrakis(4-sulfophenyl)ethylene (H TPE). With increasing RH and temperature, water molecules induce single crystal to single crystal (SCSC) transformation of iHOF-10, resulting in the formation of iHOF-11. At 90 °C, 98 % RH, the proton conductivity of iHOF-11 (7.

Cationic Nonporous Macrocyclic Organic Compounds for Multimedia Iodine Capture.

Over the past two decades, progress in chemistry has generated various types of porous materials for removing iodine ( I or I) that can be formed during nuclear energy generation or nuclear waste storage. However, most studies for iodine capture are based on the weak host-guest interactions of the porous materials. Here, we present two cationic nonporous macrocyclic organic compounds, namely, MOC-1 and MOC-2, in which 6I and 8I were as counter anions, for highly efficient iodine capture.
