Carbon nitride with electron storage property: Enhanced exciton dissociation for high-efficient photocatalysis

Ionic Carbon Nitrides in Solar Hydrogen Production and Organic Synthesis: Exciting Chemistry and Economic Advantages

“…Using this concept, Lotsch and Reisner proposed a combination of light harvesting cycle, leading to the formation of the long‐lived radical, and the dark cycle accompanied by H 2 release upon proton reduction . Zheng and Quan generated a long‐lived radical of g‐C 3 N 4 modified with cyano‐groups (CCN) and followed by the addition of O 2 producing H 2 O 2 in the dark . Ou and Wang applied this feature of carbon nitrides for simultaneous alcohols dehydrogenation and H 2 O 2 production .…”

Unconventional Photocatalysis in Conductive Polymers: Reversible Modulation of PEDOT:PSS Conductivity by Long‐Lived Poly(Heptazine Imide) Radicals

“…Related to photocatalytic applications, electrons stored in the semiconductor reduce O 2 , [19, 20] Cr IV , [10] methylviologen, [12, 21] octaatomic sulfur, [15] phenoxyl and nitroxyl radicals [18] . Long‐lived radicals of K‐PHI (hereafter referred to as (K‐PHI) .− ) are formed upon reductive quenching of K‐PHI excited state and are key intermediates driving the synthesis of cyclopentanoles by dimerization of enones, [22] dichloromethylation of enones, [23] N ‐fused pyrroles, [24] or the reductive formylation of nitroarenes via multielectron transfer [25] …”

“…[15,16] Semiconductor particles, in which electrons are accumulated near the conduction band, appear as fairly air sensitive green/blue solids and give rise to ad istinct signal in the electron paramagnetic resonance (EPR) spectra. [17,18] Related to photocatalytic applications,electrons stored in the semiconductor reduce O 2 , [19,20] Cr IV , [10] methylviologen, [12,21] octaatomic sulfur, [15] phenoxyl and nitroxyl radicals. [18] Long-lived radicals of K-PHI (hereafter referred to as (K-PHI)C À )a re formed upon reductive quenching of K-PHI excited state and are key intermediates driving the synthesis of cyclopentanoles by dimerization of enones, [22] dichloromethylation of enones, [23] N-fused pyrroles, [24] or the reductive formylation of nitroarenes via multielectron transfer.…”

Unkonventionelle Photokatalyse in leitfähigen Polymeren: Reversible Modulation der Leitfähigkeit von PEDOT:PSS durch langlebige Polyheptazinimid‐Radikale

“…Bezogen auf photokatalytische Anwendungen reduzieren die im Halbleiter gespeicherten Elektronen beispielsweise O 2 , [19, 20] Cr IV , [10] Methylviologen, [21, 12] cyclo‐Octaschwefel, [15] Phenoxyl and Nitroxylradikale [18] . Langlebige Radikale von K‐PHI (im Folgenden als (K‐PHI) .− bezeichnet) werden beim reduktiven Quenchen des angeregten K‐PHI‐Zustands gebildet und sind Schlüsselintermediate für die Synthese von Cyclopentanolen durch Dimerisierung von Enonen, [22] Dichlormethylierung von Enonen, [23] N‐anellierten Pyrrolen, [24] oder für reduktive Formylierung von Nitroarenen durch Multielektronentransfer [25] …”
