“…There is only one example of a BODIPY semiconductor showing a charge carrier mobility of >0.1 cm 2 V −1 s −1 . BODIPY π‐core possesses a unique electronic structure and its π‐architecture has a clear impact on its charge‐carrier type ,,. While π‐extension on the BODIPY's meso ‐position leads to n ‐channel semiconducting characteristics, aromatic substitutions at other positions result in p ‐channel transistor behavior .…”

The rapid emergence of organic (opto)electronics as a promising alternative to conventional (opto)electronics has been achieved through the design and development of novel π‐conjugated systems. Among various semiconducting structural platforms, 4,4‐difluoro‐4‐bora‐3a,4a‐diaza‐s‐indacene (BODIPY) π‐systems have recently attracted attention for use in organic thin‐films transistors (OTFTs) and organic photovoltaics (OPVs). This Review article provides an overview of the developments in the past 10 years on the structural design and synthesis of BODIPY‐based organic semiconductors and their application in OTFT/OPV devices. The findings summarized and discussed here include the most recent breakthroughs in BODIPYs with record‐high charge carrier mobilities and power conversion efficiencies (PCEs). The most up‐to‐date design rationales and discussions providing a strong understanding of structure‐property‐function relationships in BODIPY‐based semiconductors are presented. Thus, this review is expected to inspire new research for future materials developments/applications in this family of molecules.

In this paper, a new perylene diimide (PDI)-based acceptor Me-PDI 4 with tetrahedral configuration (or 3D) has been synthesized and characterized. Solution-processed organic solar cells (OSCs) based on Me-PDI 4 have been investigated and our results show that the device performance can reach as high as 2.73%. Our new design with tetrahedral configuration (or 3D) could be an efficient approach to increase the PCE of OSCs with non-fullerene acceptors.

“…The D–A structure is the most employed structure for tuning absorption of BODIPY. Absorptions of electron‐rich groups, such as triphenylamine, carbazole, fluorene and cyclopentadithiophene, combined with electron‐deficient BODIPY have been reported . Besides the D–A structure, donor–acceptor–donor (D–A–D) triad is also attractive because it offers the increase in cross‐section absorption and nonlinear optical behavior .…”

The boron dipyrromethene (BODIPY) triads consisting of two triphenylamine units as electron donor (D) and BODIPY core as electron acceptor (A; B3, and B4) have been synthesized using facile palladium cross‐coupling reactions to broaden the absorption of the BODIPY dyes. All dyes and intermediates were characterized by 1H NMR, 11B NMR, 13C NMR, and 19F NMR spectroscopies, UV–Vis spectroscopy, fluorescence spectroscopy, cyclic voltammetry, and time‐dependent density functional theory calculations. It was found that an increase in conjugation to the BODIPY core systematically extended the absorption and emission wavelength maxima. As a consequence, B4 containing the D–π–A–π–D structure, exhibited the longest absorption and emission maxima at 597 and 700 nm, respectively, with 1.8 eV in optical bandgap. The 96 nm red‐shifted absorption of B4 as compared to the unsubstituted BODIPY (B1) indicated the effective electronic communication between triphenylamine and BODIPY. This suggested that the proper alignment of triphenylamine and BODIPY triad could lead to broader absorption and suitable low energy bandgap. Furthermore, the molecular modeling has been employed to analyze the electronic and optical properties of the dyes. We found that the optical, electrochemical, and theoretical bandgaps of all dyes were in good agreement.
