Synthesis and Properties of Alternating Vinylene- Benzothiadiazole-Based Copolymers with Carbazole and Fluorene Derivatives for Photovoltaic Applications

International Journal of Electrochemical Science, 2014
Three vinylene-benzothiadiazole based alternating copolymers with carbazole, 3,6-difluoro carbazole and fluorene were prepared via Suzuki coupling polymerisation in the presence of catalytic amounts of palladium (II) acetate Pd(OAc)2 and tri-ortho ...

Low-dimensional hybrid perovskites containing an organic cation with an extended conjugated system : tuning the excitonic absorption features

, 2019
Low-dimensional hybrid perovskites are receiving increased attention. One of the advantages of the low-dimensional hybrids over their 3D counterparts is their greater structural flexibility towards the incorporation of bigger, more complex, organic ...

Carbazole derivatives as kinase-targeting inhibitors for cancer treatment.

Mini-Reviews in Medical Chemistry, 2020
Protein Kinases (PKs) are a heterogeneous family of enzymes that modulate several biological pathways, including cell division, cytoskeletal rearrangement, differentiation and apoptosis. In particular, due to their crucial role during human tumorigenesis

Photophysical and electrochemical properties of 9-naphthyl-3,6-diaminocarbazole derivatives and their application as photosensitizers

Journal of Photochemistry and Photobiology, 2023
A series of 3,6-diamino-9-naphthylcarbazole derivatives were synthesized and characterized experimentally and computationally. As the lowest unoccupied molecular orbital of the naphthyl group has lower energy than that of the phenyl group, a charge ...

Excitation Dynamics in Low Band Gap Donor-Acceptor Copolymers and Blends

, 2012
Donor-acceptor (D-A) type copolymers show great potential for the application in the active layer of organic solar cells. Nevertheless the nature of the excited states, the coupling mechanism and the relaxation pathways following photoexcitation are yet ...

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.
