TPET‐F2CN CMP exhibited higher CO2 uptake (2.88 mmol g−1 at 273 K) and superior Rhd B adsorption, with an equilibrium capacity of 98.12 mg g−1 and a maximum monolayer capacity of 155.6 mg g−1. ABSTRACT Herein, two conjugated microporous polymers (CMPs), TPET‐FO and TPET‐F2CN, are functionalized with carbonyl and nitrile groups.

Comparison among Different pH Values of Rhodamine B Solution Impregnated into Mesoporous Silica
We studied the behavior of different pH values of Rhodamine B solution impregnated into pores of mesoporous silica, through structural characterization techniques, such as scanning electron microscopy and porosity measurements, and spectroscopic ...

Oxidized porous silicon, composed of an elemental silicon porous skeleton coated with a silica shell, reacts with aqueous Ca2+ to generate a mixed silica–calcium silicate matrix that is remarkably efficient at trapping small molecules. With an emphasis on the engineering of controlled‐release drug delivery systems, this study identifies the factors ...

Efficient, one-pot synthesis of 14-aryl-14Hdibenzo[a, j]xanthenes in aqueous medium catalyzed by bis-piperidinium compounds [PDF]
A novel procedure for the synthesis of 14-aryl-14Hdibenzo[a,j]xanthenes through one-pot condensation of b-naphthol with aryl halides in aqueous media catalyzed by bis-piperidinium compounds is described. The method resulted in good to excellent yields in

The development of gated systems enabling controlled pore opening offers new opportunities for sensing applications. This study explores dye loading in porous and non‐porous cerasomes and pH‐dependent ATP‐triggered gating via polyamine anchors. Porous cerasomes were synthesized using block‐co‐polymers, enabling controlled proton influx and fluorescence‐

Seeding‐directed co‐assembly enables efficient chirality transfer from chiral amyloid scaffold to achiral functional molecules. Controlled assembly pathways result in hierarchical hybrid supramolecular structures showing enhanced induced electronic circular dichroism (IECD) and/or vibrational circular dichroism (IVCD).

White light emitting molecular logic gates
White light emitting smart molecules with Boolean logic computing ability are surveyed. Abstract White light emitting (WLE) materials are of considerable interest with commercial and societal applications in video displays and lighting devices. A characteristic property of WLE materials is the luminescence profile spanning from 380 to 700 nm.
