Luminescent Difluoroboron β-Diketonate PLA-PEG Nanoparticle. [PDF]

Biomacromolecules, 2017
Luminescent difluoroboron β-diketonate poly­(lactic acid) (BF2bdkPLA) materials serve as biological imaging agents. In this study, dye structures were modified to achieve emission colors that span the visible region with potential for multiplexing ...

Oxygen Sensing Difluoroboron β-Diketonate Polylactide Materials with Tunable Dynamic Ranges for Wound Imaging. [PDF]

ACS Sens, 2016
Difluoroboron β-diketonate poly­(lactic acid) materials exhibit both fluorescence (F) and oxygen sensitive room-temperature phosphorescence (RTP). Introduction of halide heavy atoms (Br and I) is an effective strategy to control the oxygen sensitivity in

Two-Photon Excited Near-Infrared Phosphorescence Based on Secondary Supramolecular Confinement. [PDF]

Adv Sci (Weinh), 2022
A multi‐stage assembly strategy involving macrocyclic confinement and nano‐confinement is reported, which induces and enhances guests’ phosphorescence with two‐photon absorption and NIR emission. Moreover, the assemblies possess excitation‐dependent emission properties, in which luminescence covers the visible and NIR regions under different excitation

Achieving White‐Light Emission Using Organic Persistent Room Temperature Phosphorescence

Angewandte Chemie, Volume 135, Issue 32, August 7, 2023., 2023
White‐light emission can be realized by purely organic phosphorescent emitters using either single‐component or host‐guest systems by mixing two fundamental colors (blue and yellow) or three primary colors (blue, green and red). Here we describe current strategies for achieving white phosphorescence at room‐temperature using organic emitters.

Circularly polarized luminescence from supramolecular assemblies based on small molecules. [PDF]

Smart Mol
This minireview outlines the recent advances of circularly polarized luminescence (CPL)‐active supramolecular assemblies based on small molecules. It covers fundamental concepts of CPL, typical design strategies of CPL‐active materials—including the assembly of chiral luminophores, the assembly of chiral components and achiral luminophores, and the ...

Synthesis, photophysical and electrochemical properties of novel and highly fluorescent difluoroboron flavanone beta-diketonate complexes [PDF]

, 2020
Difluoroboron β-diketonates complexes are highly luminescent with extensive properties such as their fluorescence both in solution and in solid state and their high molar extinction coefficients. Due to their rich optical properties, these compounds have

Achieving purely organic room temperature phosphorescence in aqueous solution

Aggregate, Volume 4, Issue 1, February 2023., 2023
Graphical abstract. Purely organic room temperature phosphorescent (RTP) materials have aroused increasing interests; however, achieving aqueous phase organic RTP emission is still a formidable challenge. This review summarizes the recent advances of organic materials with RTP emission in aqueous solution, primarily focusing on the efficient design ...

Mechanofluorochromic Difluoroboron β‐Diketonates Based Polymer Composites: Toward Multi‐Stimuli Responsive Mechanical Stress Probes

Macromolecular Rapid Communications, Volume 43, Issue 15, August 2022., 2022
Mechano‐responsive fluorescent polymer composites, obtained by incorporation of difluoroboron β‐diketonates fluorophores in linear low‐density polyethylene, are shown to be sensitive to both traction and friction forces with distinct fluorescent responses.
