Organocatalytic Asymmetric Synthesis of Spiro-Bridged and Spiro-Fused Heterocyclic Compounds Containing Chromane, Indole, and Oxindole Moieties

open access: yes, 2018
Following the reactivity inversion strategy, two different two-step sequences were designed and successfully applied to the asymmetric synthesis of spiro-bridged and spiro-fused heterocyclic compounds, which combined chromane, indole, and oxindole, three

Sleep disturbance as a transdiagnostic marker of children's mental health difficulties: A network analysis of item‐level associations between different types of sleep problems and different behavioural and emotional symptoms

open access: yesJCPP Advances, EarlyView.
Abstract Background Sleep disturbances are widely considered to be a transdiagnostic feature of common behavioural and emotional difficulties in childhood, yet most studies treat sleep as a single construct. Where studies have explored specific sleep problems to psychopathology in children, these tend to only include behavioural or emotional ...

Association of socioeconomic factors on mental health in children and young people with intellectual developmental disabilities of genetic origin

open access: yesJCPP Advances, EarlyView.
Abstract Background Children and young people (CYP) with intellectual developmental disability (IDD) have a high prevalence of mental health and behavioural problems, which might be influenced by socioeconomical status as well as the severity of their disabilities.

Molecularly Regulated Dynamic Interfaces in 3D/2D Perovskites Enabled by Functional Pyridinium Ionic Liquids

open access: yesSmall, EarlyView.
1‐butyl‐4‐methylpyridinium tetrafluoroborate (BMPyBF4) interacts with excess PbI2 during film formation, driving the formation of a low‐dimensional perovskite phase and enabling the self‐organization of a 3D/2D interfacial structure. This molecularly regulated interface suppresses defect‐mediated recombination and facilitates interfacial charge ...

Direct Synthesis of Short‐Chain Alkylammonium Capped FAPbI3 Perovskite Nanocubes for High‐Efficiency Solar Cells

open access: yesSmall, EarlyView.
Direct injection synthesis with short‐chain decylammonium iodide produces uniform FAPbI3 perovskite nanocubes through isotropic growth and surface passivation. The resulting films show reduced defect‐mediated recombination, improved phase stability, and efficient charge transport.

Smart molecular design of NIR‐II organic fluorophores through self‐driven iterative evolution, deep learning, and fragment‐based assembly

open access: yesSmart Molecules, EarlyView.
A smart design strategy for NIR‐II organic fluorophores is proposed by combining self‐driven Iterative evolution, deep Learning, and fragment‐based assembly. This work establishes a broadly applicable approach for molecular design, accelerating the discovery of NIR‐II fluorophores and extending to optoelectronic materials and therapeutic compounds ...
