Abstract The study designs and synthesizes non‐planar, propeller‐shaped hexaarylbenzene‐type (HAB) compound K5‐36 hexa‐ peri ‐hexabenzocoronene (HBC)‐based K5‐13 (with a cyclized core), as cost‐effective high‐yielding hole selective layers (HSLs) for perovskite solar cells (PSC). Using p–i–n device structure with ITO/4PADCB/HAB or HBC without)/perovskite/PDADI/PC 61 BM/BCP/Ag, the interaction is investigated between synthesized materials self‐assembled monolayer (4PADCB) elucidating mechanisms influencing growth of wide bandgap Cs 0.18 FA 0.82 Pb(I 0.8 Br 0.2 ) 3 perovskite. facilitates films larger grains lower defect density, while promoting energy level alignment at HSL/perovskite interface. These modifications effectively suppressed non‐radiative recombination, resulting in higher open‐circuit voltage 1.2V power conversion efficiency (PCE) exceeding 20% under AM 1.5G conditions. Under 3000K LED (1000 lux) illumination, PCE 4PADCB/ ‐based PSCs significantly increased from 38.02 ± 0.38% (4PADCB PSC) to 41.80 0.57%. Moreover, incorporating ‐ demonstrate exceptional stability, retaining ≈88.5% 98.2% their initial after 70 days storage glove box. findings highlight potential polyarene‐based HSLs promising approach improving PSC stability.

Abstract Due to their unique semiconducting properties, conjugated porous organic polymers (CPOPs) have garnered significant interest in various photocatalysis applications. In this study, we synthesize three thiazolo[5,4‐ d ]thiazole (TzTz)‐linked CPOPs with polyaryl rigid cores of benzene ( CPOP1) , pyrene CPOP2 ), and triazine CPOP3 ). We investigated efficacy catalyzing visible light‐driven C−N bond formation reactions, including cross‐couplings between aryl bromides amines amination reactions from sodium azides. Among the three, only combined NiCl 2 or Ni(dtbbpy)Cl effectively facilitated these transformations. Notably, exhibited photocatalytic activities approximately six times higher than its small molecular counterpart C1 both reactions. The CPOP catalyst was easily recovered through centrifugal separation reused for five catalytic cycles minimal loss activity. Theoretical calculations revealed that deliberate structural design moieties could tune energy gap, which is crucial activity This therefore, demonstrates a novel application TzTz‐linked heterogeneous
