“…Ir, Pt, Au, etc (Armaroli et al, 2007;Liu et al, 2018;Chai et al, 2015). Moreover, recent extensive research of luminescent cuprous complexes have resulted in some new interesting discoveries (Kobayashi et al, 2018;Conesa-Egea et al, 2018;Zink et al, 2013). For example, thermally activated delayed fluorescence (TADF) has been observed in many cuprous complexes.…”

A new heteroleptic phosphorescent cuprous complex supported by a BINAP ligand: synthesis, structure, luminescence properties and theoretical analyses Luminescent cuprous complexes are an important class of coordination compounds due to their relative abundance, low cost and ability to display excellent luminescence. The heteroleptic cuprous complex solvate rac-(acetonitrile-N)(3-aminopyridine-N)[2,2 0 -bis(diphenylphosphanyl)-1,1 0 -binaphthyl-2 P,P 0 ]copper(I) hexafluoridophosphate dichloromethane monosolvate, [Cu(C 5 H 6 N 2 )-(C 2 H 3 N)(C 44 H 32 P 2 )]PF 6 ÁCH 2 Cl 2 , conventionally abbreviated as [Cu(3-PyNH 2 )-(CH 3 CN)(BINAP)]PF 6 ÁCH 2 Cl 2 , (I), where BINAP and 3-PyNH 2 represent 2,2 0bis(diphenylphosphanyl)-1,1 0 -binaphthyl and 3-aminopyridine, respectively, is described. In this complex solvate, the asymmetric unit consists of a cocrystallized dichloromethane molecule, a hexafluoridophosphate anion and a complete racemic heteroleptic cuprous complex cation in which the cuprous centre, in a tetrahedral CuP 2 N 2 coordination, is coordinated by two P atoms from the BINAP ligand, one N atom from the 3-PyNH 2 ligand and another N atom from a coordinated acetonitrile molecule. The UV-Vis absorption and photoluminescence properties of this heteroleptic cuprous complex have been studied on polycrystalline powder samples, which had been verified by powder X-ray diffraction before recording the spectra. Time-dependent density functional theory (TD-DFT) calculations and a wavefunction analysis reveal that the orange-yellow phosphorescence emission should originate from intraligand (BINAP) charge transfer mixed with a little of the metal-to-ligand charge transfer 3 (IL+ML)CT excited state. research papers Acta Cryst.

Metal ions often influence the photoswitching efficiency of ap hotochromic system.T his article reports ao nedimensional polymer having cyclic azobenzenes coordinated to silver ions that are bridged by nitrates. The coordination polymer (CP-2)d isplays ap hotoresponsive behavior.T he switching ability in the polymer form was faster compared to the parenta zobenzene ligand withoutt he metal ions. Azobenzenes are reported to be poorlyc onducting. Here, although the azobenzene ligand does not show significant electronic mobility,t he coordination polymer (CP-2)d isplays am odest conductivity.T he conductance in the cis form of the polymer is significantly higher compared to the trans form. Upon exposure to visible light, the cis form undergoes photoisomerization to the trans form with ad rastic drop in the electronic mobility.T he trans form can be reverted to the cis form thermally or by using UV light.Thus,t his system offers ar eversible control of the conductivity using light.
