WebMay 5, 2024 · The spin-selectivity by chiral molecules causes the spins of two unpaired electrons in OH· to align parallel to produce a triplet O 2, while prohibiting the generation of the singlet H 2 O 2 (Figure 7b ). This results in more efficient O 2 production and longer electrode durability. WebThe Chirality-Induced Spin Selectivity (CISS) effect, a unique ‘spin filtering’ effect arising from the structural handedness of organic compounds (i.e., chirality) and their assemblies that lack inversion symmetry [1]. It utilizes chirality to generate robust spin information from chiral (left- (S) or right-handed (R)) molecules without ...
