A high performance three-dimensional (3D) thiophene-annulated perylene dye, namely tetra-PBI-S, was designed and synthesized. The appropriate LUMO level, balanced carrier mobilities and favourable phase separation make tetra-PBI-S based solar cells show a much higher power conversion efficiency (PCE) of 6.2% than tetra-PBI based solar cells with a PCE of 3.6%.

The title compound, (C(24)H(20)P)(2)[MnI(4)]·(CH(3))(2)CO, prepared from the reaction of manganese powder, iodine and tetra-phenyl-phospho-nium iodide in acetone shows a tetra-hedral complex anion [Mn-I = 2.6868 (5)-2.7281 (4) Å and I-Mn-I = 104.011 (13)-116.164 (15)°], two tetra-phenyl-phospho-nium cations and one mol-ecule of acetone.

We report a new transient spectral method utilizing triplet excited state as sensitive reporters to monitor and differentiate the multiplex G-quadruplex/ligand interactions in a single assay, which is a difficult task and usually requires a combination of several techniques. From a systematic study on the interactions of porphyrin (TMPyP4) with each telomeric G-quadruplex: AG3(T2AG3)3, G2T2G2TG...

The title manganese(II) substituted gallophosphate, K(0.5)Rb(0.5)[Ga(2)Mn(PO(4))(3)(H(2)O)(2)], features a three-dimensional network built of PO(4) tetra-hedra, GaO(5) trigonal bipyramids and MnO(6) octa-hedra. The Rb(I) and K(I) ions, which are disordered with respect to each other in a 1:1 ratio, occupy sites within the channels of the framework. The Rb(I)/K(I) and Mn(II) atoms occupy positio...

In the title compound, C(8)H(8)N(4), the dihedral angle between the tetra-zole and benzene rings is 21.6 (1)°. An inter-molecular C-H⋯π inter-action is observed.

The crystal structure of the title compound, (C(12)H(30)N(2))[CoCl(4)], is composed of discrete (C(12)H(30)N(2))(2+) cations and [CoCl(4)](2-) anions. The asymmetric unit contains a half-cation and a half-anion. The atoms of the cation occupy general positions about an inversion centre, which is located at the midpoint of the central C-C bond. The Co atoms lie on a twofold rotation axis. The sl...

The title compound, [Cu(C(16)H(32)N(4))](C(14)H(14)O(2)PS(2))(2) or [Cu(trans[14]dien)][S(2)P(OC(6)H(4)Me-4)(2)](2), where trans[14]dien is meso-5,7,7,12,14,14-hexa-methyl-1,4,8,11-tetra-azacyclo-tetra-deca-4,11-diene, was obtained by the reaction of [Cu(trans[14]dien)](ClO(4))(2) and [(C(2)H(5))(2)NH](2) [S(2)P(OC(6)H(4)Me-4)(2)](2). The Cu(II) atom lies on a centre of inversion and possesses ...

Colorless transparent single crystals of trilanthanum hexa-silicon undeca-nitro-gen, La3Si6N11, were prepared at 0.85 MPa of N2 and 2273 K. The title compound is isotypic with Sm3Si6N11. Silicon-centered nitro-gen tetra-hedra form a three-dimensional network structure by sharing their corners. Layers of one type of SiN4 tetra-hedra and slabs composed of the two different La(3+) cations and the ...
