Thiazole Boron Difluoride Dyes with Large Stokes Shift, Solid State Emission and Room-Temperature Phosphorescence

Jieping Zhu, Wei Wang, Shuo Tong

The small Stokes shift and weak emission in the solid state are two main shortcomings associated with the boron-dipyrromethene (BODIPY) family of dyes. This study presents the design, synthesis and luminescent properties of boron difluoro complexes of 2-ar ...

Block Copolymer Stabilized Liquid Nanodroplets Facilitate Efficient Triplet Fusion-Based Photon Upconversion in Solid Polymer Matrices

Felipe Andres Saenz Padilla

Sensitized triplet-triplet annihilation-based photon upconversion is a photo-physical process that affords anti-Stokes-shifted emission after annihilation of two metastable triplet excitons of an emitter dye and the formation of a fluorescent singlet state ...

"Doubly Orthogonal" Labeling of Peptides and Proteins

Jérôme Waser, Beat Fierz, Nora Guidotti, Raphaël Michel Henri Simonet-Davin, Romain Gaëtan Tessier

Herein, we report a cysteine bioconjugation methodology for the introduction of hypervalent iodine compounds onto biomolecules. Ethynylbenziodoxolones (EBXs) engage thiols in small organic molecules and cysteine-containing peptides and proteins in a fast a ...

Ultralow Dissipation Mechanical Resonators for Quantum Optomechanics

Tobias Kippenberg, Alberto Beccari, Dalziel Joseph Wilson, Nils Johan Engelsen, Sergey Fedorov, Ryan Daniel Schilling, Amir Hossein Ghadimi

We demonstrate dissipation dilution engineering techniques for ultralow dissipation mechanical resonators. The Si3N4 nanobeams show quality factors (Q) as high as 800 million and Q x f exceeding 10(15) Hz-both records at room temperature. (C) 2019 The Auth ...

Photolabile coumarins with improved efficiency through azetidinyl substitution

Pablo Rivera Fuentes, Zacharias Thiel, Eric Vauthey

Azetidinyl substituents have been recently used to improve the fluorescence quantum yield of several classes of fluorophores. Herein, we demonstrate that other useful photochem. processes can be modulated using this strategy. In particular, we prepd. and m ...

Fluorescence Quenching in BODIPY Dyes: the Role of Intramolecular Interactions and Charge Transfer

Antonio Prlj, Laurent Alexis Clément Vannay

The fluorescence properties of the BODIPY dye and its two meso-substituted derivatives, tert-butyl- and phenyl-BODIPY, are rationalized. The non emissive behavior of the latter two are attributed to the energetically accessible low-lying conical intersecti ...

Strongly Red-Shifted Photoluminescence Band Induced by Molecular Twisting in Cyanine (Cy3) Dye Films

Frank Nüesch, Roland Hany, Jakob Heier, Surendra Babu Anantharaman, Chuyao Peng

Cyanine dye molecules, used as monomers or in aggregate form, find interesting applications in optoelectronic devices. Among the various aggregate species incorporating organic dyes, centrosymmetric dimers are known as nonluminescent. They can act as excit ...
