Abstract Developing highly efficient photocatalysts for artificial photosynthesis is one of the grand challenges in solar energy conversion. Among advanced photoactive materials, conjugated porous polymers (CPPs) possess a powerful combination high surface areas, intrinsic porosity, cross‐linked nature, and fully π‐conjugated electronic systems. Here, based on these fascinating properties, organic–inorganic hybrid heterostructures composed CPPs TiO 2 photocatalytic CO reduction H evolution...
Abstract Here, the use of high‐performance microfluidic techniques (HPMT) is reportedto afford conjugated porous polymer (CPPs) with smaller particle size and narrower dispersion than obtained by miniemulsion methodology. Specifically, polymers based on BODIPY or BOPHY dyes are synthesized HPMT conditions conventional conditions. The textural properties from notably improved, giving rise to high‐quality thin films that photoelectrochemically characterized. Furthermore, hybrid materials CPPs...
Molecular shuttles are the basis of some most advanced synthetic molecular machines.

Abstract α‐Allenols were catalytically transformed into dihydrofurans in the presence of platinum dichloride. Notably, using dichloride along with silver triflate as catalytic system, α,β‐unsaturated ketones obtained. Therefore, role salt may not just consist activation precatalyst. magnified image
The divergent behavior of two homologue allenals, namely, 2-(buta-2,3-dienyloxy)- and 2-(propa-1,2-dienyloxy)benzaldehydes, as cyclization substrates is described. 2-(Buta-2,3-dienyloxy)benzaldehydes suffers a formal allenic carbocyclization reaction to afford chromenes, whereas 2-(propa-1,2-dienyloxy)benzaldehydes react yield chromones. formation chromenes strictly hydroarylation process divided into parts, Claisen-type rearrangement oxycyclization. An unknown N-heterocyclic carbene...
A new method to measure the mechanical strength of single hydrogen bonded host–guest systems under non-equilibrium conditions.
The divergent and selective syntheses of two types annelated β-lactams, namely, furan- tetrahydropyridine-fused 2-azetidinones, have been accomplished directly from 2-azetidinone-tethered oxazolidine-enynes through gold catalysis.
Abstract We show that H-bonded host–guest systems associate in ionic liquids (ILs), pure salts with melting point below room temperature, which dipole–dipole electrostatic interactions should be negligible comparison dipole-charge interactions. Binding constants ( K a ) obtained from titrations of four two organic solvents and yield smaller yet comparable values than solvents. also detect the association event using force spectroscopy, confirms binding is not solely due to (de)solvation...
The development of applicable functional materials currently stands as one the main challenges in field On-Surface Synthesis. In this direction, it is necessary to understand their stability real conditions, what known bridging pressure gap. Interestingly, although well-established that on-surface synthesis will be highly influenced by selected substrate, little about effect underlying substrate on air synthesized nanostructures. Applying an On-surface Synthesis approach, we report a similar...
