Abstract Ultralong organic phosphorescence (UOP) crystals have attracted increased attention due to the distinct photophysical property of a long-lived lifetime. However, are generally brittle, leading serious problem for their application in flexible technology. Herein, we report three types elastic (EOCs) with ultralong via introducing halogen atoms (Cl, Br, I) into π-conjugated phosphorescen...

A series of 4,5-dibromo-2-(4-substituted phenyl)hexahydro-3a,6-epoxyisoindol-1(4H)-ones were synthesized by reaction the corresponding 2-(4-substituted phenyl)-2,3,7,7a-tetrahydro-3a,6-epoxyisoindol-1(6H)-ones with [(Me2NCOMe)2H]Br3 in dry chloroform under reflux for 3−5 h. In contrast to 4-F and 4-Cl substituents, one bromine atoms isoindole moiety behaves as a halogen bond donor formation int...

the effects of substituents on the symmetry and the nature of halogen bonds in [n∙∙∙x∙∙∙n]+-type systems are presented for the yc5h4n∙∙∙x∙∙∙nc5h5 (y = no2, cn, h, ch3, och3, oh, nh2, x = cl, br, i) complexes. some structural parameters, energy data and electronic properties were explored with the density functional theory (dft) calculations. in addition, electrostatic potentials were used in es...

in the crystal structure of the title polymeric compound, [c42h38n6o33sr5.2(h2o)]n, five independent metal atoms (sr1-sr5) have different coordination environments. the sr1 and sr5 atoms are nine coordinated and feature distorted tricapped trigonal-prismatic and capped square-antiprismatic geometries, respectively. the rest srii atoms have eight coordination numbers. these units are connected v...

In the crystal structure of the title compound, [ZnCl(2)(C(5)H(4)ClN)(2)], discrete complex mol-ecules are found in which the Zn(II) cations are coordinated by two chloride anions and the N atoms of the two 3-chloro-pyridine ligands within a slightly distorted tetra-hedron. Moreover, inter-molecular C-Cl⋯Cl-C halogen inter-actions (Cl⋯Cl = 3.442 Å) are found between the building blocks.

The title compound, C18H25BrO, crystallized as a racemate with four independent mol-ecules in the asymmetric unit. In the crystal, three of these four mol-ecules are linked via C-Br⋯Br-C halogen bonds [Br⋯Br = 3.662 (2) and 3.652 (2) Å], forming dimers.

stability of the π-π stacking interactions in the ben||substituted-coronene and hfben||substituted-coronene complexes was studied using the computational quantum chemistry methods (where ben and hfben are benzene and hexaflourobenzene, || denotes π-π stacking interaction, substituted-coronene is coronene molecule which substituted with four x groups, and x= nh2, ch3, oh, h, f, cf3, cn and no). ...
