有机-无机杂化钙钛矿结合手性有机分子被证明是一类新的手性半导体。根据手性有机物的S-和R-构型，手性钙钛矿表现出相反符号的圆二色性（CD）。CD信号也可以通过改变手性钙钛矿膜的晶体取向和厚度来改变。
An organic-inorganic hybrid perovskite incorporating chiral organic molecules is demonstrated as a new class of chiral semiconductors. Chiral perovskites exhibit oppositely-signed circular dichroism (CD) according to the S- and R-configurations of chiral organics. The CD signals can be also varied by changing the crystalline orientation and thickness of the chiral perovskite films.
