Exploring the Potential of Zero‐Dimensional Carbon Nanomaterials in Photoluminescent, Electrochemiluminescent and Electrochemical Sensors

Advanced Materials Interfaces, EarlyView.
Zero‐dimensional carbon nanomaterials are presented as multifunctional platforms linking structure, property, and sensing performance. Surface engineering and heteroatom doping modulate electron‐transfer and luminescent behavior, enabling electrochemical, photoluminescent, and electrochemiluminescent detection. Fundamental design principles, analytical

Phosphaalkenylidene bridged ferrocenes

Journal of Organometallic Chemistry, 2012
The lithiation of ferrocenylphosphane Fc-PH(2) (Fc = -C(5)H(4)FeC(5)H(5)) has been reinvestigated and both Fc-PHLi and Fc-PLi(2) have been identified by NMR-spectroscopy. The lithiated phosphanides have been converted to the corresponding mono and bis(silylated) species the latter of which gave synthetic access to an oligomer in which three ferrocene ...

(2-Bromoacetyl)ferrocene [PDF]

Acta Crystallographica Section E Structure Reports Online, 2011
Dans le titre mol-ecule, [Fe(C(5)H(5))(C(7)H(6)BrO)], les atomes de C du cycle substitué ont des longueurs de liaison Fe-C disparates par rapport au cycle non substitué. Dans le résidu bromo-acétyle, les atomes Br et O sont coplanaires [l'angle de torsion O-C-C-Br est de 5,7 (4)°] et sont synchrones entre eux.

Water‐Stable Paper‐Based Laser‐Induced Graphene With Asymmetric Water Adhesion and Wettability

Advanced Materials Interfaces, EarlyView.
Paper‐based electronics are attractive for sustainable and disposable devices, but often fail in wet environments. By introducing Parafilm into cellulose paper combined with laser conversion, two graphene surfaces with different water interactions are created.

Shaping Carbon Nitrides for Advanced Macrostructures

Advanced Materials Technologies, EarlyView.
This review examines how carbon nitride can be shaped through a range of printing and interfacial assembly methods. By bringing together additive manufacturing and liquid–liquid structuring concepts, carbon nitride is moving beyond its traditional powder‐based photocatalyst form toward digitally designed robust macroscale architectures with high design
