Water-Promoted Generation of a Diazairida Homobarrelene by C—C Coupling Between an Iridacyclic Alkylidene and Acetonitrile
The stable cationic iridacyclopentenylidene [TpMe2Ir(=CHC(Me)=C(Me)CH2(NCMe)]PF6(A;TpMe2=hydrotris (3,5dimethylpyrazolyl)borate) has been obtained by α-hydride abstraction from the iridacyclopent-2-ene [TpMe2Ir(CH2C(Me)=C(Me)CH2)(NCMe)]. Complex A exhibits...
Design and realization of transparent solar modules based on luminescent solar concentrators integrating nanostructured photonic crystals
Herein, we present a prototype of a photovoltaic module that combines a luminescent solar concentrator integrating one-dimensional photonic crystals and in-plane CuInGaSe2 (CIGS) solar cells. Highly uniform and wide-area nanostructured multilayers with photonic...![A Diels–Alder Reaction Triggered by a [4 + 3] Metallacycloaddition](https://www.ciccartuja.es/wp-content/uploads/sites/4/2024/11/15_06.jpg)
A Diels–Alder Reaction Triggered by a [4 + 3] Metallacycloaddition
The TpMe2Ir(III) complex 1-OH2 (TpMe2 = hydrotris(3,5-dimethylpyrazolyl)borate), which contains a labile molecule of water and an iridium-bonded alkenyl moiety (−C(R)═C(R)–(R=CO2Me)) as part of a benzo-annulated five-membered iridacycle, reacts readily with the...
Spatial Fluctuations in Expression of the Heterocyst Differentiation Regulatory Gene hetR in Anabaena Filaments
Under nitrogen deprivation, filaments of the cyanobacterium Anabaena undergo a process of development, resulting in a one-dimensional pattern of nitrogen-fixing heterocysts separated by about ten photosynthetic vegetative cells. Many aspects of gene expression before...
