“…This particular BE is commonly related to aromatic diphenylphosphane derivatives which are either unbound [60] or coordinatively bound to zero-valent transition metals in metal complexes. [61] In view of the relatively high film density and orientational order, it is very likely in our case that most of the diphenylphosphanyl headgroups are characterised by coordination-type attachment to the gold surface.…”

1,1'-Difunctionalised ferrocene derivatives have been studied, which contain groups suitable for chemisorption on gold substrates, namely -NC, -PR(2) as well as a range of sulfur-containing units like -NCS, -SR, and thienyl. Thin films on gold have been fabricated from solution with most of these adsorbate species. Film thickness, composition and structure were investigated primarily by X-ray photoelectron and near-edge X-ray absorption fine-structure spectroscopy. The quality of self-assembled monolayers fabricated from 1,1'-diisocyanoferrocene (1) and 1,1'-diisothiocyanatoferrocene (2) turned out to be superior to that of films based on the other adsorbate species investigated. In addition to the surface coordination behaviour of 1 towards gold substrates, relevant aspects of the molecular coordination chemistry of 1 have also been addressed, including the synthesis and characterisation of [(mu-1){Cr(CO)(5)}(2)], [Ag(2)(mu-1)(2)](NO(3))(2) x H(2)O and [(mu-1)(AuCl)(2)]. The crystal structure of the gold complex is governed by aurophilic interactions and can be taken as a model for the arrangement of 1 in self-assembled monolayers on gold.

“…As shown in Figure e and Table S1, the URTP CDs mainly contain C, N, O, and P elements with compositions to be 50.3 %, 6.78 %, 34.6 %, and 8.32 %, respectively, indicating relatively high doped N and P in the CDs. The HR XPS spectrum of C 1s indicates the presence of C−C/C=C (284.6 eV), C−N (285.2 eV) and C−O (286.2 eV) bonds in the CDs (Figure f) . The XPS N 1s spectrum contains three components that can be assigned to C−N=C (399.5 eV), N−(C) 3 (400.4 eV), and N−H (401.2 eV), respectively (Figure g) .…”

Facile, Quick, and Gram‐Scale Synthesis of Ultralong‐Lifetime Room‐Temperature‐Phosphorescent Carbon Dots by Microwave Irradiation

et al. 2018

Long-lifetime room-temperature phosphorescence (RTP) materials are important for many applications,but they are highly challenging materials owing to the spin-forbidden nature of triplet exciton transitions.Herein, afacile,quick and gram-scale method for the preparation of ultralong RTP (URTP) carbon dots (CDs) was developed via microwaveassisted heating of ethanolamine and phosphoric acid aqueous solution. The CDs exhibit the longest RTPl ifetime,1 .46 s (more than 10 stonaked eye) for CDs-based materials to date. The doping of Nand Pelements is critical for the URTP which is considered to be favored by an!p*t ransition facilitating intersystem crossing (ISC) for effectively populating triplet excitons.I na ddition, possibilities of formation of hydrogen bonds in the interior of the CDs may also play asignificant role in producing RTP.P otential applications of the URTP CDs in the fields of anti-counterfeiting and information protection are proposed and demonstrated.

“…Both spectra demonstrate a major contribution at lower binding energies, which most likely belong to sp 2 -hybridized aromatic carbon atoms and were referenced to 284.5 eV. [18,19] The Cu 2p photoelectron and Cu LMM X-ray Auger electron spectra (Figure 10, a and b, respectively) indicate that copper is present mostly in the 2+ oxidation state. The latter ratio considerably contradicts the theoretical value (1:6) and could be explained by the formation of extra carbon in the X-ray beam from pump oil and other organic contamination on the surface of the samples.…”

Copper(II) Complexes with Aromatic o‐Phosphorylated Phenols – Synthesis, Crystal Structures, and X‐ray Photoelectron Spectroscopy

The structural properties of copper complexes with (2-hydroxyphenyl)di-p-tolylphosphane oxide (CuL 1 2 ) and 3-(2-hy-2 ) are studied in detail. The o-phosphorylated phenols demonstrate both bridging and chelating behaviour, and the main reaction product is a coordination polymer containing dimeric Cu 2 O 8 fragments. The structural peculiarities of the o-phosphorylated phenols were revealed by single-crystal X-ray diffraction. The copper complexes are [a]
