The introduction of chirality into organic-inorganic hybrid perovskites (OIHPs) is expected to achieve excellent photoelectric and nonlinear materials related to circular dichroism. Owing to the existence of asymmetric center and intrinsic chirality in the chiral OIHPs,the different efficiencies of second harmonic generation (SHG) signal occurs when the circularly polarized light (CPL) with different phases passes through the chiral crystal, whichisdefined as second harmonic generation circular dichroism (SHG-CD). Here,the SHG-CD effect is developed in bulk single crystals of chiral onedimensional (1D) [(R/S)-3-aminopiperidine]PbI 4 .Itisthe first time that CPL is distinguished using chirality-dependent SHG-CD effect in OIHPs bulk single crystals.S uchS HG-CD technology extends the detection range to near infrared region (NIR). In this way,t he anisotropyf actor (g SHG-CD )t hrough SHG-CD signal is as high as 0.21.
