A selenophene-containing conjugated organic ligand 2-(4'-methyl-5'-(5-(3-methylthiophen-2-yl)selenophen-2-yl)-[2,2'-bithiophen]-5-yl)ethan-1-aminium (STm) is synthesized and incorporated into Sn(II)-based two-dimensional perovskites, (STm)2SnI4. By introducing the STm ligand, the band offset between perovskite and ligand can be...
