Advanced Science, EarlyView.This work presents novel enamine‐based self‐assembling monolayers with engineered anchoring groups as hole‐selective contacts for inverted perovskite solar cells. The conjugated molecular design suppresses interfacial defects, optimizes charge extraction, and prevents aggregation.

Alternative products to carbazoles in the oxidation of diphenylamines with palladium (II) acetate [PDF]
, 1997 Although simple diphenylamines are conveniently oxidised with Palladium (II) acetate to give carbazoles, for more complex examples, carbazoles are minor products amongst many.CRUP (Portugal). British Council - Treaty of Windsor Programme.

Aggregation‐Controlled Triplet Exciton Regulation Enables Single‐Emitter Color‐Evolving Afterglow
Advanced Science, EarlyView.A single‐emitter system based on DTP‐R luminophores enables time‐evolving afterglow through aggregation‐regulated excited‐state dynamics. The coexistence and suppression of delayed fluorescence and phosphorescence are controlled via concentration tuning and host‐guest engineering, revealing the RISC origin of delayed fluorescence and enabling ...

Synthesis of Carbazoles by Intramolecular Arylation of Diarylamide Anions
, 2016 The synthesis of a series of substituted 9H-carbazoles by the photostimulated SRN1 substitution reaction with diarylamines as starting substrate was performed. The diarylamines were obtained by two approaches, the Pd-catalyzed reactions (Buchwald−Hartwig)

Oxidative Coupling of Carbazoles: A Substituent-Governed Regioselectivity Profile
, 2018 Oxidative C–C coupling of carbazoles possessing various substituents is demonstrated in the presence of organic (metal-free) recyclable oxidants, such as DDQ or CA/H+, for accessing bicarbazole regioisomers.

Quantum‐Trained AI Enables Inverse Design of Organic Frontier Orbitals at Billion‐Scale
Advanced Science, EarlyView.Quantum‐trained AI links molecular substructures to frontier‐orbital energetics and enables interpretable screening across nearly one billion GDB‐13 molecules. By combining fragment‐ and ring‐level insights with donor–acceptor energy alignment against ITIC, the framework narrows an immense chemical space to a small set of promising candidates and ...
