Molecules capable of producing zero-field circularly polarized phosphorescence (CPP) are highly valuable for chiroptoelectronic applications that rely on triplet exciton. However, the paucity tractable molecular design rules obtaining CPP emission has inhibited full utilization. We report amplification by formation helical co-assemblies consisting achiral square planar cycloplatinated complexes and small fractions homochiral complexes. The latter a unique Pfeiffer effect during superhelical...
Abstract While cracks are usually considered detrimental, crack generation can be harnessed for various applications, example in ceramic materials, via directing propagation and opening. Here, we find that electron beam irradiation prompts a suppression phenomenon copper (Cu) thin film on polyimide substrate, allowing the control of formation terms both location shape. Under tensile strain, form unirradiated region Cu whereas prevented irradiated region. We attribute this to enhancement...
Chiral photodetectors, optoelectronic devices that can detect circularly polarized light (CPL), have attracted much attention as building blocks of next-generation information technology. However, their performance has been severely limited by the tradeoff between external quantum efficiency (ηE) and dissymmetry factor photocurrent, latter typically being small absorption (gA). This work numerically demonstrates a circular polarization-sensitive organic photodetector (CP-OPD) based on chiral...
For organic solar cells (OSCs) based on nonplanar phthalocyanines, it has previously been reported that a thin film composed of triclinic crystals with face-on (or flat-lying)-oriented molecules, typically obtained CuI template layer, is desired for optical absorption in the near-infrared (NIR) spectral region. However, this work demonstrates PbPc−C60 donor–acceptor pair, less orientation broader distribution new layer consisting ZnPc/CuI bilayer more desirable terms cell efficiency than...
