Silanediol-Bay-Bridge Rigidified Axially Chiral Perylene Bisimide.

Chiral organic molecules with a complementing π-structure are highly desired to obtain materials with good semiconducting properties and pronounced chirality effects in the visible region. Herein, we introduce a novel design strategy to achieve an axially chiral and rigid perylene bisimide (PBI) dye by attaching the chirality-inducing 2,2'-biphenoxy moiety at one side of the bay area and the rigidity-inducing di--butylsilanediol bridge on the other side. This yielded a new bay-functionalized PBI derivative carrying the combination of a highly rigid and, simultaneously, an axially chiral perylene core.

Clinical, Hematological, and Biochemical Profile in Seropositive Dengue Cases at a Tertiary Care Hospital in Nepal.

Dengue virus infection is a major source of morbidity and mortality in the majority of tropical and subtropical nations. In Nepal, the first case of dengue was reported in 2004, followed by numerous outbreaks exerting a critical impact on public health. This study aims to describe the clinical and laboratory characteristics of dengue patients visiting a tertiary care hospital to see the trend of presentation.

Upconverting Luminescent MOF for Highly Sensitive Dual-Mode Recognition of Synthetic Dyes.

Lanthanide-based luminescent materials hold promise in sensing applications due to their distinct optical properties. Though advancements in lanthanide-based metal-organic frameworks (MOFs) have enhanced downshifting luminescence, achieving upconversion remains challenging. In this effort, we prepared upconverting ytterbium-doped europium MOFs (%Yb-EuMOFs; = 10, 20, and 30) via the solvothermal method using 2,6-naphthalenedicarboxylic acid (NDC) as an organic linker.
