“…Recently, Demyanov et al reported 1D-coordination polymers based on AsPh 3 ([Cu 2 I 2 (AsPh 3 ) 2 ( L )] n : L = pyrazine, 4,4′-bipyridine) during the preparation of this manuscript. 12 In the previous paper, the halogen species of the polymers were limited to iodine, and the effects of the N-heteroaromatic co-ligands or external stimuli were not studied. In this work, AsPh 3 and six types of bidentate N-heteroaromatic co-ligands were used for CuX (X = Br, I) 1D-coordination polymers (Fig.…”

“…Indeed, several rhomboid-containing complexes (Cu 2 I 2 P 4 ) have been reported to exhibit TADF [22][23][24]. This is true for other soft ligand complexes involving the rhomboid motif Cu 2 I 2 L 4 (L = N-, As-, or P-ligand) [24][25][26][27]. Conversely, to the best of our knowledge for Cu 4 I 4 L 4 -cubane-containing materials (L = N-, P-, S-ligand), the literature exhibits no evidence for TADF.…”

The prediction of the metal cluster within a coordination polymer or complex, as well as the dimensionality of the resulting polymer or complex (i.e., 0D, 1D, 2D, or 3D), is often challenging. This is the case for Ph2P(CH2)mPPh2 ligands (1 ≤ m ≤ 8) and CuX salts, particularly for X = I. This work endeavors a systematic statistical analysis combining studies in the literature and new data, mapping the nature of the resulting CuI aggregates with eight different diphoshphines in 2:1, 3:2, 1:1, 2:3, and 1:2 CuI:Ph2P(CH2)mPPh2 molar ratios as a function of m, which lead to either pure products or mixtures. Several trends are made relating stoichiometry and chain length to the CuI cluster formed (i.e., globular vs. quasi-planar). Four new X-ray structures were determined: [Cu3I2(L1)3]I, Cu3I3(L2)2, Cu2I2(L6)2, and Cu4I4(L8)2, where m is, respectively, 1, 2, 6, and 8, in which the CuxIy central aggregates adopt triangular bipyramid, diamond, rhomboid, and cubane shaped motifs, respectively. Photophysical measurements assisted the establishment of trends considering the paucity of the crystallographic structures. During this study, it was also found that the 0D-complex Cu2I2(Ph2P(CH2)5PPh2)2 exhibits thermally activated delayed fluorescence.

“…Potentially, arsine/stibine ligands can also improve X-ray scintillation efficiency of the Cu 4 I 4 clusters through higher X-ray absorption ability of As/Sb nuclei compared to N, P, or S nuclei. However, despite the recent progress in studying Cu(I)-arsine emitters by Naka, [47][48][49] Karasik, [50,51] and our groups, [46,[52][53][54] these compounds still remain poorly explored. In particular, they have never been demonstrated in X-ray scintillation or white light LED (WLED) applications.…”

Rare‐earth element‐free materials that exhibit strong room temperature phosphorescence (RTP) and X‐ray scintillation properties are gaining global interest incessantly in the recent years. This work reports a series of easily synthesizable cubane Cu4I4‐triarsenic clusters [Cu4I4(R3As)3L] (L = none or nitrile), that exhibit a strong yellow‐green RTP with quantum efficiencies up to 100% and short decay times (4.4–4.9 µs). The title cluster complexes display X‐ray scintillation properties with a record ultralow detection limit (18.1 nGy s−1) and a perfectly linear dose rate response within a remarkably wide dose rate window (0–640 µGyair s−1). The cluster [Cu4I4(Ph3As)3] is highlighted as an efficient phosphor for UV‐pumped white and yellow LED devices, demonstrating an excellent white spectrum with a CIE index of (0.32,0.33) and bright yellow emission, respectively. These results may stimulate the future efforts in designing highly efficient arsenic‐based RTP materials and enriching the Cu4I4 cluster family.
