Abstract In recent years, conjugated polymers have received widespread attention due to their characteristic advantages of light weight, favorable solution processability, and structural modifiability. Among various polymers, fluorinated ones developed rapidly achieve high‐performance n ‐type or ambipolar polymeric semiconductors. The uniqueness contains the high coplanarity structures, lower frontier molecular orbital energy levels, strong nonbonding interactions. this review, first building blocks, including benzene thiophene rings, B←N bridged units, fluoroalkyl side chains are summarized. Subsequently, different synthetic methods described, with a special focus on respective disadvantages. Then, these numerous structures appropriate bear in mind, properties applications such as cyclopentadithiophene‐, amide‐, imide‐based embedded systematically discussed. introduction fluorine atoms can further enhance electron‐deficiency backbone, influencing charge carrier transport performance. promising applied widely organic field‐effect transistors, solar cells, thermoelectric devices, other opto‐electric devices. Finally, outlook challenges future development is

ConspectusAromatic compounds are important in synthetic chemistry, biomedicines, and materials science. As a special type of aromatic complex, transition-metal-based metallaaromatics contain at least one transition metal an framework. The chemistry has seen much progress computational studies methods, but their properties applications still emerging. In recent years, we have disclosed series metal-centered conjugated polycyclic metallacycles which carbon chain is chelated to center through three metal-carbon bonds. These termed carbolong complexes exhibit good stability water, oxygen, light, heat on account polydentate chelation aromaticity, making them easy handle. Carbolong not only π-conjugated aromatics also organometallics; therefore, they the both species. this Account, showcase advances based different properties.First, kind aromatic, with ability transmit electrons, allowing function as single-molecule conductors candidates for electron transporting layer (ETLs) solar cells. A been proved be useful achievable ETLs enhance device performance organic cells perovskite cells.Second, due involvement d orbitals conjugation, normally strong broad absorption, even some cases extending near-infrared region (NIR). absorbed optical energy can converted into heat, ultrasound; consequently, used core moieties smart materials. For example, 7C were found aggregation-enhanced emission (AIEE). Some 12C designed NIR-responsive polymers, such cylindrical materials, self-healing shape memory contrast stereotypically toxic osmium highly OsO4, low cell cytotoxicity biocompatibility; potential biomedical area. benefiting from absorption NIR, 9C photoacoustic imaging photothermal therapy, respectively. addition, photodynamic therapeutic take advantage peroxo complex discussed.Third, transition-metal by carbon-based ligands, displayed catalytic activity dehydrogenation alcohols bimetallic catalyze difunctionalization reactions unactivated alkenes.Overall, applied photovoltaics, phototherapy, reactions.
