“…We use BODIPY dyes, which have received a considerable amount of attention in various fields due to their versatile photophysical properties. They possess large molar absorptivity coefficients, fluorescence quantum yields close to unity, sharp absorption and emission bands, and high photostability. , The synthesis of these dyes is relatively straightforward, which makes functionalization and modification, and with this tuning of the photophysical properties possible. − Due to these properties, BODIPY dyes and their derivatives are used in a wide array of fields such as biological imaging, − sensing, − potential agents for photodynamic and photothermal therapy, − solar cells, − and optoelectronics. − …”

The morphology of films containing photoactive materials is crucial for the performance of solid-state dye applications. Organic dyes tend to crystallize due to their usually planar molecular structure and the resulting intermolecular interactions. This leads to inhomogeneous films with crystalline, aggregated, and amorphous regions, decreasing device efficiency and complicating spectral analysis. Improving the glass-forming ability of organic dyes therefore presents a major challenge for solid-state dye applications. Here, we present a guideline to create organic dye glasses using BODIPY as a model dye. The method is based on the strategic design of BODIPY derivatives, equipped with short alkyl chains, in combination with blending of two or more derivatives. Mixing increases the entropy of the liquid state and lowers the thermodynamic driving force for crystallization as well as the kinetic fragility of the system. This enables the fabrication of homogeneous thin films without any additives. In these films, the dye molecules are trapped in a glassy state, featuring monomeric absorption and emission. This strategy leads to a BODIPY material with an amorphous character in thin films, dropcast films, and bulk. Further, the strategy is based on thermodynamics and is therefore expected to be general, enabling the transformation of any dye molecule into a glass former.

“…The introduction of various substituents into structure I allows varying these properties and make them dependent on the medium, which is in demand in various applications [10]. BODIPY derivatives are currently widely used as fluorescent dyes [18], chemosensors [19,20], fluorescent probes [21,22], laser dyes [23,24] and as compounds for photodynamic therapy [25][26][27].…”

Oxidative C-H/C-H Coupling of Dipyrromethanes with Azines by TiO2-Based Photocatalytic System. Synthesis of New BODIPY Dyes and Their Photophysical and Electrochemical Properties

et al. 2021

Oxidative C-H/C-H coupling reactions of dipyrromethanes with azines in the presence of a heterophase oxidative photocatalytic system (O2/TiO2/visible light irradiation) were carried out. As a result of cyclization of obtained compounds with boron trifluoride etherate, new hetaryl-containing derivatives of 4,4-difluoro-4-boron-3a,4a-diaza-s-indacene were synthesized. For the obtained compounds, absorption and luminescence spectra, quantum yields of luminescence as well as cyclic volt-amperograms were measured.
