All-Polymer Microcavities for the Fluorescence Radiative Rate Modification of a Diketopyrrolopyrrole Derivative
(American Chemical Society, 2022)
Controlling the radiative rate of emitters with macromolecular photonic structures promises flexible devices with enhanced performances that are easy to scale up. For instance, radiative rate enhancement empowers low-threshold ...
Multifunctional Heteropentalenes: From Synthesis to Optoelectronic Applications
(American Chemical Society, 2022)
In the broad family of heteropentalenes, the combination of two five-membered heterocyclic rings fused in the [3,2-b] mode has attracted the most significant attention. The relatively straightforward access to these ...
Polarized, V-Shaped, and Conjoined Biscoumarins: From Lack of Dipole Moment Alignment to High Brightness
(American Chemical Society, 2022)
Eleven conjoined coumarins possessing a chromeno[3,4-c]chromene-6,7-dione skeleton have been synthesized via the reaction of electron-rich phenols with esters of coumarin-3-carboxylic acids, catalyzed by either Lewis acids ...
Novel Method for the Synthesis of Merocyanines: New Photophysical Possibilities for a Known Class of Fluorophores
(Wiley, 2023)
A new, transformative method for the preparation of rhodols and other merocyanines from readily available tetrafluorohydroxybenzaldehyde and aminophenols has been developed. It is now possible to prepare merocyanines bearing ...
Conformation of the Ester Group Governs the Photophysics of Highly Polarized Benzo[g]coumarins
(American Chemical Society, 2023)
Photosensitizers that display “unusual” emission from upper electronically excited states offer possibilities for initiating higher-energy processes than what the governing Kasha’s rule postulates. Achieving conditions for ...
Biomimetic Fe–Cu Prophyrrole Aerogel Electrocatalyst for Oxygen Reduction Reaction
(American Chemical Society, 2023)
The development of bioinspired catalysts for oxygen reduction reaction is one of the most prominent pathways in the search for active materials to replace Pt-based catalysts in fuel cells. Herein, we report innovative ...
Conversion of Ketones into Blue-Emitting Electron-Deficient Benzofurans
(Wiley, 2023)
A novel heavy metal-free and safe synthetic methodology enabling one-step conversion of ketones into corresponding 4,5,6,7-tetrafluorobenzofurans (F4BFs) has been developed. The presented approach has numerous advantageous ...
Green-Emitting 4,5-Diaminonaphthalimides in Activity-Based Probes for the Detection of Thrombin
(American Chemical Society, 2022)
The natures of electron-donating groups as well as the bridge between them determine the fate of substituted 1,8-naphthalimide molecules in the excited state. An activity-based probe constructed from a selective peptide ...
Saddle-shaped aza-nanographene with multiple odd-membered rings
(Royal Society of Chemistry, 2023)
A saddle-shaped aza-nanographene containing a central 1,4-dihydropyrrolo[3,2-b]pyrrole (DHPP) has been prepared via a rationally designed four-step synthetic pathway encompassing intramolecular direct arylation, the Scholl ...
From 2,5-Diformyl-1,4-dihydropyrrolo[3,2-b]pyrroles to Quadrupolar, Centrosymmetric Two-Photon-Absorbing A–D–A Dyes
(American Chemical Society, 2022-03-28)
An original approach has been developed for the insertion of formyl substituents at positions 2 and 5 of 1,4-dihydropyrrolo[3,2-b]pyrroles by conversion of thiazol-2-yl sub stituents. The synthetic utility of these formyl ...
