Transcription of Chirality from Metal-Organic Framework to Polythiophene.

Here, we report an unprecedented chirality transfer from a metal-organic framework (MOF) to a polymer. In this work, unsubstituted polythiophene (PTh) was prepared in the nanochannels of a chiral MOF. Circular dichroism spectroscopy revealed that nanoconfinement of the polymer chains could endow optically inactive PTh with a chiral nature.

Spiral Eu(iii) coordination polymers with circularly polarized luminescence.

A spiral-type chiral Eu(iii) coordination polymer showed strong luminescence (emission quantum yield Φf-f = 57% and photosensitized energy transfer efficiency ηsens = 53%) and effective CD and CPL properties (gCPL = 0.17) when compared with a mono-nuclear chiral Eu(iii) complex in the solid state (Φf-f = 36%, ηsens = 14%, and gCPL = 0.09).

Pulsed laser induced heat transfer from a phthalocyanine-based thin film to a Bi, Al-substituted DyIG substrate: photothermal demagnetization observed by magnetic circular dichroism and numerical analysis.

We have investigated the demagnetization of a ferrimagnetic substrate, Bi, Al-substituted dysprosium iron garnet (Bi0.8Dy2.2Fe4.
