Using density functional theory (DFT) in conjunction with ultraviolet (UPS) and X‐ray photoelectron spectroscopy (XPS), we investigated a number of complexes and macromolecules. We have shown on a large set of UPS, XPS, and DFT data that the calculated Kohn–Sham energies of organic and metalorganic complexes can be used as approximate ionization energies (IEs). It is possible to evaluate IEs with an accuracy of 0.1 eV with the density functional approximation (DFA) defect approach. This method has been successfully tested on a large number of boron β‐diketonates and d‐metal chelate and sandwich complexes. We interpreted the bands in the valence region of the XP spectra of macromolecular organosilicon compounds in the solid state by taking into account the density of states and the ionization cross‐sections. According to DFT calculation results, the one‐electron states in the valence region of the model compounds correlate with the positions of the spectral band maxima. © 2015 Wiley Periodicals, Inc.

“…The BODIPYs and the other 1,3-diketonates are well studied by DFT and TD-DFT methods for the better understanding of the molecular properties at ground and excited states [17,18,31]. Reports on the theoretical study of the difluoroboron curcumin analogs and their photophysical properties are elusive.…”

“…However most of the reported difluoroboron complexes show very small stokes shifts and hardly show any solid state fluorescence. In recent years new class difluoroboron complexes such as boron-diketonates [15][16][17], anilin imines (anils) and/or moieties containing b-iminoenolate ligands with improved properties as solid state fluorescence, sensitivity upon changes in polarity of the microenvironment and aggregation induced http fluorescence [4,15,[18][19][20][21][22] have been developed. The difluoroboron complex of curcumin was initially developed with increased stability and inhibitory potency against HIV protease [23].…”

The synthesis and application of organoboron complexes are a highly relevant topic owng to their unique characteristics. Based on their emissive properties, these complexes have been used to make novel optical materials and devices; boron β-diketonate is a simple and robust organoboron complex. From a series of recent studies, unique and versatile optical properties have been reported. In this review, we introduce the results of primarily recent studies on boron diketonate and related compounds containing polymers and particularly explain their optical properties. Initially, the multi-emission of boron diketonate derivatives and its application to biotechnology are explained. Next, the formation of nanostructures and its emission properties are demonstrated. The modulation of optical properties by mechanical stress is also presented. Finally, recent progress in the development of solid-emissive materials are shown with boron diketonates and their derivatives, which have aggregation-induced emission properties. The versatility of boron diketonates as a building block for the preparation of functional optical materials is the focus of this review.
