Interface engineering has been proven a powerful tool to improve performances of the perovskite solar cells (PSCs). Herein, highly π-conjugated graphdiyne (GDY) is employed as an interface linker between film and hole transport layer (HTL). It found that GDY can significantly suppress formation metallic Pb (a detrimental defect), reduces carrier recombination. The also form π-π stacking interac...

We have synthesized three new isoindigo-based small molecules by extending the conjugated length through the incorporation of octyl-thiophene units between the isoindigo core and benzothiophene terminal units. Both UV-vis and Grazing incidence X-ray diffraction experiments show that such extension of the π-conjugated backbone can induce H-aggregation, and enhance crystallinity and molecular ord...

Perovskites The π-conjugated ionic compound QAPyBF4 was used as a perovskite modulator in the Research Article by Juin-Jei Liou, Taiho Park, Zong-Xiang Xu, and co-workers (e202117303). Experimental investigations showed that p-type conjugated cations [QAPy]2+ adsorb on surface with under-coordinated Pb highly electronegative [BF4]− anions enriched at SnO2 interface. This spontaneous diffusion e...

Boron nitride nanotubes (BNNTs) are functionalized and solubilized in organic solvents such as chloroform, methylene chloride, and tetrahydrofuran by using conjugated poly(p-phenylene ethynylene)s (PPEs) (polymers A and B) and polythiophene (polymer C) via a noncovalent functionalization approach through strong π-π stacking interactions between the conjugated polymers and BNNTs. The functionali...

The light-harvesting properties of two fluorescent dynamic conjugated microporous organic polymers (Py-PP and Py-BPP) rendered with pyrene chromophores are described. The hydrophobic and dynamic nature of these porous frameworks allows the selective capture of various organic solvents by instantaneous swelling at room temperature. Moreover, the dynamic nature of these frameworks indicates the s...

Abstract Two novel nonlinear optical isomorphous crystals of proline derivatives with alkyne functionality have been obtained (Boc-L-ProNH(CH 2 ) CCH and Boc-cis-4-fluoro-L-ProNH(CH CCH). Both derivatives, which differ only by the substitution a H atom to F atom, adopt same polar columnar right-handed helix arrangement in crystalline state. In addition, adjacent helical columns all point direct...
