Recent advances in organophosphorus–chalcogen and organophosphorus–pincer based macrocyclic compounds and their metal complexes

Abstract

The design and development of phosphorus based macrocycles containing one or more other hetero atoms is a crucial emphasis for the enhancement of modern synthetic chemistry. In recent years focus...

Synthesis and Photophysical Properties of Heavier Pnictogen Complexes

“…Naka and Imoto groups reported a series of dicopper complexes containing triphenylarsine (AsPh 3 ) and N-heteroaromatic co-ligands. [57] The reactions of CuI with an equimolar amount of AsPh 3 in the presence of large excess of N-donor ligands (L) such as pyridine (py), 2-picoline (pic), 2,6-lutidine (lut), and quinoline (qn), afforded dimeric complexes [Cu 2 (μ 2 -I) 2 (AsPh 3 ) 2 (L) 2 ] (L = py (11), pic (12), and qn (13)) and [Cu 2 (μ 2 -I) 2 (AsPh 3 ) 2 (lut)] ( 14). The steric hindrance around the nitrogen atom of lut causes the structural difference among these complexes as evinced by single crystal X-ray analysis.…”

“…[4][5][6] Phosphorus-based compounds have only recently drawn attention as optoelectronic materials, and as a result, significant progress has been achieved in the study of organophosphorus compounds over the past ten years. [7][8][9] Due to the diagonal relation of phosphorus with carbon, various families of phosphorus-based compounds, including phosphaalkenes, [10] iminophosphines, [11][12] diphosphenes, [10] phosphaalkynes, [13] phosphinines, [14] and phospholes, [15][16] have been developed. This has created new opportunities for the logical development of novel compounds made up of heavier main group elements.…”

Unraveling Ultralong Phosphorescence in Ar2PO(H): n(O) → σ*(P-C) Transitions in Ar2PO(H) Stabilize Triplet States Better than n(P) → σ*(P-C) in Ar3P

“…Recently, phosphorus-based organic luminophores have been widely explored for optoelectronic applications owing to their unique geometry and scope for chemical modification via oxidation of the phosphorus center. − In this context, triarylphosphine oxides have enormous applications in catalysis, materials, medicines, etc. − However, the luminescence properties of these molecules are seldom reported in the literature. According to El-Sayed’s rule, the spin-forbidden intersystem crossing from S 1 → T n can be facilitated via n → π* transition in the presence of heteroatoms containing at least a lone pair of electrons .…”

Mechanosynthesis of Higher‐Order Cocrystals: Tuning Order, Functionality and Size in Cocrystal Design**

“…Recently, cyclodiphosphazane species[ 30 , 31 ] have been demonstrated as robust [32] and versatile[ 33 , 34 , 35 ] supramolecular building blocks in binary cocrystal formation. [ 33 , 36 , 37 , 38 , 39 ] However their use for the synthesis of multicomponent crystals beyond binary systems, remains unexplored.…”
