Abstract: Abstract Two cyanyl-carboxylic derivatives (PYCZA and TPYCZA) have been designed and synthesized with flexible or rigid substituents, respectively. The persistent phosphorescence mechanism was studied through temperature-dependent Raman spectroscopy, and single/powder X-ray diffraction. The low temperature… read more here.

Abstract: Due to the wide spectral absorption and ultrafast electron dynamical response under optical excitation, topological insulator (TI) was proposed to have appealing application in next-generation photonic and optoelectronic devices. Whereas, the bandgap-free speciality of Dirac… read more here.
