High-Performance Synthesis of Phosphorus-Doped Graphene Materials and Stabilization of Phosphoric Micro- and Nanodroplets

A thermally induced cascade process leading to the formation of stable micro- and nanometer-size phosphoric droplets was developed starting from a molecular precursor. Microwave-induced pyrolysis of 1,2,3,4,5-pentaphenylphosphole oxide proceeded through a

Structural and theoretical insights into the AIE attributes of phosphindole oxide: The balance between rigidity and flexibility

Multiple intramolecular motions consume the excited-state energy of luminogenic molecules upon photoexcitation and lower the emission efficiency. The low frequency rotational motion of aromatic rings can be facilely restricted by steric constraint in the

Intense fluorescence of 1-aryl-2,3,4,5-tetraphenylphosphole oxides in the crystalline state

A series of 2,3,4,5-tetraphenylphosphole oxides with various aryl groups on the phosphorus atoms were synthesized and their fluorescence properties in the crystalline state were investigated. Some of these compounds showed an intense fluorescence with the

Cobalt Metallacycles. 8. Preparative and Kinetic Studies on the Reactivity of Cobaltacyclopentadienes with Phosphites

(η5-Cyclopentadienyl)(triphenylphosphine)cobaltacyclopentadiene complexes, (CoCR1=CR2CR3=CR4)(η5-C5H5)(PPh3) (1), react with phosphites, P(OR5)3 (2), yielding in successive steps (η5-cyclopentadienyl)(phosphite)cobaltacyclopentadiene complexes, (CoCR1=CR2CR3=CR4)(η5-C5H5)5)3> (3) and isomeric 1-alkoxyphosphole oxide complexes (4).The structure of one isomer of the 1-methoxyphosphole oxide complex, 4ca-2, was determined by an X-ray crystallographic structural analysis.The complexes 4, when oxidized by Ce4+ ions, give 1-alkoxyphosphole oxides.Kinetic studies on the formation of 3 and the conversion of 3 to 4 have been carried out and a first-order reaction has been verified in the complex concentration for both steps.Activation parameters for the reaction of 1c (R1, R2, R3, R4 = Ph) with 2a (OR5 = OCH3) are determined as ΔH(excit.) = 31 kcal mol-1 and ΔS(excit.) = 4 eu for the substitution, and as ΔH(excit.) = 22 kcal mol-1 and ΔS(excit.) = -4 eu for the conversion step, respectively.The preparative and kinetic investigations show that (1) both steric and electronic factors of the substituents of the cobalt metallacycles govern the substitution step, and (2) the electronic factor chiefly governs the conversion step.The steric effect of the alkyl groups of 2 is very distinctive in the conversion step.
