Effect of Sterically Protective Groups on the Aromaticity of Fully Unsaturated Oligoquinanes

, 2023
Oligoquinane derivatives have unique aromatic properties, which dictate the stability of the molecules and their potential applications in various devices. Due to the challenge in their synthesis, systematic studies of these molecules are still lacking.

Study of Aromaticity in Phosphazenes

, 2010
The denition of aromaticity and aromatic character of conjugated organic and inorganic systems has been of long-standing interest to chemists. Widely different properties such as molecular geometry, stabilization energy, and magnetic properties have been

Double Aromaticity of Franck-Condon Excited States of Cyclo[16]carbon

, 2023
Excited-state aromaticity of molecular rings is a very interesting and meaningful topic. Inspired by the recent realization of cyclo[16]carbon (C16) with double anti-aromaticity characteristics of singlet ground state (S0 state), here we demonstrate that

The Study of Y-Aromaticity. IV. Tridentenes with Irregular Arm Lengths

, 2021
To increase the number of synthetic targets having Y-aromaticity, we proposed (n, l, m)-tridentenes, in which the lengths of the three linear conjugated systems, extending from the central atom of the Y-shaped structure of n-tridentene were made ...

Aromaticity and Antiaromaticity in the Excited States of Porphyrin Nanorings

, 2019
Aromaticity can be a useful concept for predicting the behavior of excited states. Here we show that π-conjugated porphyrin nanorings exhibit size-dependent excited-state global aromaticity and antiaromaticity, for rings containing up to eight porphyrin ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Global Aromaticity and Antiaromaticity in Porphyrin Nanoring Anions

, 2019
Doping, through oxidation or reduction, is often used to modify the properties of π-conjugated oligomers. In most cases, the resulting charge distribution is difficult to determine.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...
