英文摘要: Abstract(#br)Ruddlesden-Popper two-dimensional (2D) organic-inorganic hybrid perovskites have been explored for multiple applications, benefitting from their structural tunability, superior stability and congenital quantum-well effects. Herein, two bilayer hybrid perovskite-type compounds with the general formula [A 2 B n-1 Pb n I 3n+1 ] ( n is the number of layer) [(C 5 H 8 NS) 2 (MA)Pb 2 I 7 ] ( 1 ) and [(C 5 H 8 NS) 2 (FA)Pb 2 I 7 ] ( 2 ) (C 5 H 8 NS: 2-thiophenemethylamine, MA: methylamine, FA: formamidine) are reported. The differential scanning calorimetry (DSC) measurements revealed both compounds 1 and 2 exhibit reversible phase transitions above the room temperature, accompanied by dielectric anomalies near the Curie temperature (T c ). The variable-temperature X-ray...
