Abstract
Regioregular and random conjugated polymers based on a boron-fused azomethine unit were synthesized by Sonogashira-Hagihara cross coupling reaction. Although these polymers exhibited similar optical properties in the solution states, a distinct difference was observed in the aggregation forming ability in the film states; scanning electron microscope (SEM) observation indicated the existence of fiber-like aggregates in the spin-coated film of the regioregular polymer, while regiorandom polymer showed no aggregate in the film state. Accordingly, the UV-vis absorption spectrum of the regioregular polymer showed an increased shoulder peak due to the aggregate formation, whereas the random one showed no change. Furthermore, an absolute fluorescence quantum efficiency of the regioregular polymer was enhanced in response to the aggregate disassembly via thermal annealing treatment. In this study, we demonstrate that controlling regioregularity of the conjugated polymers can induce the different morphological structures and thermal-responsive behaviors. These findings could be beneficial for the design strategy and potential applications of thin-film optoelectronic devices with stimuli-responsive properties.

Abstract
π-Conjugated molecules with acceptor-donor-acceptor (A-D-A) electronic structures make up an important class of materials due to their tunable optoelectronic properties and applications in, for example, organic light-emitting diodes, nonlinear optical devices, and organic solar cells. The frontier molecular orbital energies, and thus band gaps, of these materials can be tuned by varying the donor and acceptor traits and π-electron counts of the structural components. Herein, we report the synthesis and characterization of a series of A-D-A compounds consisting of BF2 formazanates as electron acceptors bridged by a variety of π-conjugated donors. The results, which are supported by density functional theory calculations, demonstrate rational control of optoelectronic properties and the ability to tune the corresponding band gaps. The narrowest band gaps (EgOpt = 1.38 eV and EgCV = 1.21 eV) were observed when BF2 formazanates and benzodithiophene units were combined. This study provides significant insight into the band gap engineering of materials derived from BF2 formazanates and will inform their future development as semiconductors for use in organic electronics.

Abstract
![]()
The reactivity of
a boron complex with a redox-active formazanate ligand, LBPh2 [L = PhNNC(p-tol)NNPh], was studied. Two-electron
reduction of this main-group complex generates the stable, nucleophilic
dianion [LBPh2]2–, which reacts with
the electrophiles BnBr and H2O to form products that derive
from ligand benzylation and protonation, respectively. The resulting
complexes are anionic boron analogues of leucoverdazyls. N–C
and N–H bond homolysis of these compounds was studied by exchange
NMR spectroscopy and kinetic experiments. The weak N–C and
N–H bonds in these systems derive from the stability of the
resulting borataverdazyl radical, in which the unpaired electron is
delocalized over the four N atoms in the ligand backbone. We thus
demonstrate the ability of this system to take up two electrons and
an electrophile (E+ = Bn+, H+) in
a process that takes place on the organic ligand. In addition, we
show that the [2e–/E+] stored on the
ligand can be converted to E• radicals, reactivity
that has implications in energy storage applications such as hydrogen
evolution. A boron complex with a redox-active
formazanate ligand in its two-electron-reduced state is shown to react
with electrophiles (BnBr and H+). The resulting “borataleucoverdazyl”
products have weak N−C and N−H bonds; homolytic cleavage
reactions lead to stable ligand-based radicals. Thus, the accumulation
of [2e−/E+] on the formazanate ligand
and conversion to E• radicals are demonstrated,
and their potential relevance in energy-related electrocatalysis (e.g.,
proton reduction) is discussed.

Abstract
The application of our newly developed B-C coupling method by catalytic Si/B exchange is demonstrated for the synthesis of a series of triarylboranes (1), monodisperse thienyl- and furylborane dimers (2) and trimers (9), extended oligomers (3) and polymers (3'), as well as mixed (oligo)thienyl-/furylboranes. The structures of 1 aaTip , 1 bbTip , and 2 bbbMes* , determined by X-ray crystallography, reveal largely coplanar hetarene rings and BR3 environments, which are most pronounced in the furylborane species. Photophysical investigations, supported by TD-DFT calculations, revealed pronounced π-electron delocalization over the hetarene backbones including the boron centers. With an extended series of derivatives of varying chain lengths available, we were able to determine the effective conjugation lengths (ECL) of poly(thienylborane)s and poly(furylborane)s, which have been reached with the highest-molecular-weight derivatives of our study. Through variation of the furan-to-thiophene ratio, the photophysical properties of these materials are effectively modulated. Significantly, higher furan contents lead to considerably increased fluorescence intensities. Compounds 1 aaTip , 1 bbTip , and 3 aTip showed the ability to bind fluoride anions. The binding process is signaled by a distinct change in their optical absorption characteristics, thus rendering these materials attractive targets for sensory applications.

Abstract
Click polymerization, a powerful synthetic technique to construct polymers with unique structures and advanced functions, is of crucial importance in the areas of polymer and material sciences. A variety of click polymerizations such as azide-alkyne, thiol-yne, amino-yne, and hydroxyl-yne reactions have been established, wherein the catalytic systems play an indispensable role in realizing these highly practical reactions based on triple-bond building blocks, as they directly influence the efficiencies of the click polymerizations and the performances of the resultant polymers. The vital employment of catalysts is reviewed and their developments from innovative discoveries to the eminent position are outlined. Moreover, the challenges and perspectives in this area are also briefly discussed.
