Nickel‐Free Perovskite Solar Cells Enabled by Self‐Assembled Monolayers: A Pathway to Efficient and Recyclable Devices

Advanced Energy Materials, EarlyView.
Replacing toxic NiOx with phenyl‐substituted phosphonic‐acid carbazole monolayers (Ph‐5PACz) yields inverted perovskite solar cells that are efficient and recyclable. The nickel‐free interface reaches 25.3% efficiency and enables closed‐loop ITO recovery with near‐98% performance retention, while life‐cycle and techno‐economic analyses confirm lower ...

Oxygen‐Tolerant, Controlled Synthesis of Degradable and Water‐Soluble Poly(Vinyl Amide)s via Radical Ring‐Opening Copolymerization of Cyclic Dithiothreitol

Angewandte Chemie, EarlyView.
Oxygen‐tolerant photoinduced electron/energy transfer reversible addition–fragmentation chain transfer (PET‐RAFT) polymerization enables the controlled radical ring‐opening (rROP) copolymerization of cyclic dithiothreitol (cDTT) with less‐activated vinyl monomers, affording degradable polymers with predictable molecular weights, low dispersities, and ...

Efficient OLEDs Fabricated by Solution Process Based on Carbazole and Thienopyrrolediones Derivatives

Molecules, 2018
Four low molecular weight compounds—three of them new, two of them with carbazole (Cz) as functional group and the other two with thienopyrroledione (TPD) group—were used as emitting materials in organic light emitting diodes (OLEDs).

Fluorene‐Framework Engineering Enables Narrowband Red Multi‐Resonance Emitters for High‐Efficiency With Negligible Roll‐Off Toward BT.2020

Angewandte Chemie, EarlyView.
σ‐Decoupled C9 fluorene‐framework topology control enables narrowband red MR emitters. SF‐BNO and PF‐BNO share the same BNO core, but differ in closed/open fluorene ring closure. SF‐BNO improves steric shielding and stability, while PF‐BNO enhances PLQY, orientation, and efficiency. Ex‐PSF and TE‐OLED architectures deliver ultra‐low efficiency roll‐off

Isolation and description of a stable carbazole-degrading microbial consortium consisting of Chryseobacterium sp NCY and Achromobacter sp. NCW

, 2008
A stable microbial consortium, separated from a refinery wastewater sample, was able to utilize carbazole as the sole source of carbon, nitrogen, and energy, and liberated ammonia from excess nitrogen.

Carbazole-corrole and carbazole-prophyrin dyads: Synthesis, fluorescence and electrochemical studies

, 2015
Donor-acceptor type carbazole-corrole and carbazole-porphyrin dyads 4-9 were synthesized and characterized. Corrole and porphyrin containing one meso-p-iodophenyl group were coupled to N-butyl-3-ethynyl-carbazole by a modified Sonogashira reaction.

1,3,6-Tribromo-9-ethyl-9H-carbazole

IUCrData, 2016
In the title compound, C14H10Br3N, the carbazole ring system is almost planar, with an r.m.s. deviation of 0.023 Å from the best fit mean plane of the 13 non-H atoms of the three rings. The methyl C atom lies 1.232 (3) Å out of this plane.
